We would like to introduce a case where the movable industrial air purifier 'QleanAir FS 70' was used as a measure against nasal congestion and dryness of the eyes and mouth for employees in a food factory. In food factories, employees may experience nasal congestion and dryness of the eyes and mouth due to powdered raw materials. By capturing airborne dust derived from these raw materials with our product, we create a space with higher air cleanliness. At a cheese factory, one of our clients reported that employees were experiencing nasal congestion and dryness of the eyes and mouth due to powdered potato additives. After installing the movable industrial air purifier 'QleanAir FS 70', it was found that the dust concentration in the air decreased by approximately 75%. Symptoms of nasal congestion and dryness of the eyes and mouth among employees also improved, leading to better hygiene conditions in the work environment. *Clean Air Scandinavia has various case studies available. We encourage you to consider introducing our products to food factories as well.

When air blowing is performed for the purpose of reducing cleaning time in equipment, although the objects may become clean, the dust and particles blown away by the air will disperse in that area. As a result, they may adhere to other equipment or processing machines, potentially causing malfunctions or affecting product yield rates. Many customers may face the challenge of insufficient cleaning due to reasons such as staff shortages. By installing Clean Air Scandinavia's "FS 70 Standard," airborne dust throughout the factory can be captured by filters. This helps to reduce the adhesion of airborne dust blown away by air to other equipment and processing machines, and decreases the accumulation of dust and dirt in hard-to-reach high areas, ultimately reducing the frequency of cleaning. Depending on the size of the target area, measurements taken at actual customer sites have shown that the amount of airborne dust in the range of 0.3 to 1.0 µm has decreased by approximately 75% compared to operational conditions. Additionally, we will propose appropriate airflow and types of filters based on the specific conditions of the site.

Forklifts, which are active in factories and warehouses, generate airborne dust and particles as their hard tires wear down. Additionally, dust can accumulate on forklifts in manufacturing and logistics sites, as well as at charging stations. As a result, even in spaces where maintaining air cleanliness is desired, airborne dust and particles may be transported along with the movement of forklifts. The FS 70 Standard captures fine dust particles in factories and warehouses that cannot be collected by dust collectors. By capturing airborne dust, it contributes to creating a cleaner air environment. Furthermore, depending on the conditions at the site, we will propose the appropriate processing airflow and type of filter.

In the process of removing the black scale (black rust) from the surface of carbon steel (general steel) after heat treatment (tempering), "shot blasting" is performed. Although the main body of the equipment is equipped with a dust collection system, it cannot completely eliminate the invisible dust, and within a day, the workers' masks become completely black. The size of this workspace is 120 square meters with a height of 5 meters, resulting in a volume of 600 cubic meters. The QleanAir FS 70 Standard (suspended dust cleaner) has an air processing capacity of 3000 cubic meters per hour, capturing suspended dust and supplying air that has been filtered. With the introduction of one unit, the air is replaced every 12 minutes. As a result, after the operation of the QleanAir FS 70 Standard, it was confirmed that the amount of suspended dust was reduced by approximately 50% compared to before operation. Additionally, by equipping the large intake port at the front of the suspended dust collector with an optional pad filter, it is possible to reduce the deterioration of the main filter. Clean Air Scandinavia's suspended dust cleaners offer options tailored to customer needs even in harsh environments, effectively solving issues related to suspended dust.

We would like to introduce a case where the "QleanAir FS70 Standard" floating dust cleaning machine was used to capture fine dust that could not be removed by dust collectors in a woodworking workshop as a measure against airborne dust. Even in woodworking workshops where local exhaust systems, overall ventilation, and dust collectors are used, there may still be issues with airborne dust. By capturing airborne dust with this product and improving the air environment, a safer workplace can be achieved. Additionally, it helps prevent dust accumulation on production equipment, leading to reduced maintenance and the prevention of malfunctions. Similar challenges may also be encountered in factories producing paper products (such as paper and cardboard), where paper dust is generated. Depending on the conditions of the site, we will propose appropriate processing airflow and types of filters.

We would like to introduce a case where the use of the airborne dust cleaning machine "QleanAir FS70 Standard" prevented malfunctions caused by dust accumulation in automated racks. When dust accumulates on automated racks used in logistics facilities and warehouses, it can lead to malfunctions or stoppages of the racks. This product captures fine dust particles in factories and warehouses that cannot be removed by conventional dust collectors. By collecting airborne dust, it helps prevent malfunctions and stoppages of automated racks. Additionally, it reduces the accumulation of dust on stored items, thereby minimizing the need for cleaning. We will propose an appropriate airflow rate based on the conditions at the site.

Residual particles (dust, debris, powder, metal fragments, etc.) floating in the production line can cause product defects, leading to reduced yield, equipment interruptions, and delays in delivery. Improvements can be made regarding the following main phenomena: - Defective products / test failures - Corrections / reprocessing - Customer complaints / recalls The QleanAir FS70 Standard supplies purified air with a processing airflow of 3,000 cubic meters per hour. As a guideline, at a ceiling height of 5 meters, it is effective over an area of 300 square meters. (Further improvements can be expected in narrower spaces.) By installing the QleanAir FS70 Standard, it equates to two air changes per hour. The concentration of floating particles is significantly reduced, leading to an improved environment in a cleaner production line.

You must create a clean indoor environment, but are you giving up because the construction costs are too high? By using the industrial air purifier 'FS70', which requires no construction, approximately 95% of the dust particles floating in the work environment are captured by the filter, and clean air is discharged. In other words, the 'FS70' can create a pseudo "clean room"! The 'FS70' is a product that excels at collecting airborne dust particles smaller than 25 micrometers, which have a longer suspension time before falling, and cannot be captured by dust collection devices. We can select filters tailored to your concerns, and it can also be used in conjunction with other dust control measures.

When prototyping with a plastic injection molding machine, there may be a lot of static electricity generated indoors during the prototype stage of product development. When static electricity occurs, it can charge fibers and cause them to adhere to the product, often resulting in an increased rate of defects in subsequent processes. In printing factories where temperature and humidity management must be kept constant, Japan's climate faces various issues depending on the region. The 'FS70', which can be used without construction, maintains consistent performance regardless of temperature and humidity. Filters can be selected to address the concerns of customers working on-site, and it can also be used in conjunction with other dust control measures.

In small to medium-sized factories located within residential and commercial facilities, consideration for the surrounding community is necessary. When working with windows open, are you troubled by complaints from nearby residents about "laundry getting dirty," "odors," or "noise"? With the 'FS70,' installation work is not required, it is portable, and it commits to a processing air volume of 3,000 cubic meters per hour. This means that with just one unit, it can replace the air in an indoor environment of about 500 cubic meters approximately every 10 minutes. Even when exhausting air outside, it effectively captures a large amount of dust, allowing you to use it with peace of mind.

In workplaces using organic solvents, a single misstep can lead to serious health hazards, making on-site measures crucial. At a packaging printing company, two units of the industrial air purifier 'FS70' from "Clean Air Scandinavia" were installed in an area of approximately 900 cubic meters. Measurements of air concentration before and after installation showed a reduction of about 60% in PPM values. As one of the measures to prevent health hazards for our important employees, we recommend the introduction of high-performance industrial air purifiers. *Note: The 'FS70' is not explosion-proof.*

During mass production of plastic parts, a large amount of static electricity is generated in injection molding. Dust and fine fibers in the air adhere to products and molds, leading to the occurrence of defective products and malfunctions or stoppages of machinery. This problem is particularly serious in winter when the air is dry. By extending the upper duct of the industrial air purifier 'FS70' from "Clean Air Scandinavia" and flexibly setting the injection area, it is possible to create a clean area that acts as a pseudo "wind barrier." It has also been verified within the company that it is effective not only in localized areas but also in relatively wide spaces. If you are struggling with yield rates in plastic molding or equipment cleaning, please consider implementing this solution.

Plastic tends to accumulate static electricity, which attracts dust and debris floating in the air in various situations such as manufacturing, assembly, and transportation. If dust adheres to plastic and enters the assembly process, it can lead to "foreign matter contamination," resulting in defective products. Additionally, inhalation exposure to plastic dust can cause significant health damage to the human body. The 'FS70' requires no installation work, is movable, and commits to a processing air volume of 3,000 cubic meters per hour. It powerfully sucks in air containing plastic dust and debris, filters it through a filter, and reliably delivers the purified air to the designated area. It contributes to reducing yield loss and preventing health damage to workers. It is expected to be even more effective in environments where adequate ventilation cannot be achieved. Please consider it.

Starting in the autumn of 2023, our company has taken on a new business that requires air blowing processes. We were troubled by the deterioration of the working environment and the impact on product quality due to dust dispersion. In April 2023, we encountered the movable and easily transportable Clean Air Scandinavia 'FS70' at the Nagoya Factory Equipment and Supplies Exhibition, and we decided to implement it. The 'FS70' efficiently captures dust generated by air blowing, improving the working environment. It also helps suppress dust adhesion to products, contributing to enhanced product quality. The key points of the implementation are as follows: - Movable and adaptable to layout changes - Decision to implement based on reference to other companies' dust control examples - Filter replacement conducted while observing the level of dirtiness In the future, we anticipate an increase in the frequency of filter replacements due to the increased air blowing from used shipping boxes; however, this will not be a problem as we can continue to manage it on-site. Additionally, establishing a pseudo-clean room may further enhance the collection and adsorption effects. For the improvement of the environment to deliver high-quality products to our customers, we encourage you to consider the introduction of Clean Air 'FS70'.

We would like to introduce a case where our air purifiers were installed, one each, in two restaurants within the Diamond Hotel Co., Ltd. The company has been taking various measures, including ventilation, to prepare for issues related to infectious diseases and hygiene, but felt the need to enhance their infection control measures further. The installation time was very short, which was great. It took about 10 minutes from bringing in the air purifiers to installation and operational checks, so there was almost no impact on business. Regarding maintenance after installation, users tend to forget or find it cumbersome, but we have been well acquainted with Clean Air since the days of the smoking cabins, and I feel confident leaving it to the manufacturer. *For more details, please refer to the PDF materials or feel free to contact us.*

At a food manufacturing factory in Nara Prefecture, it was a challenge that dust was generated during the process of employees bundling and inspecting products. The industrial air purifier FS70 that was introduced showed a certain level of effectiveness in suppressing dust, and after verification in a high-performing site, the number of units increased from one to two. This is an example of contributing to the improvement of the working environment and enhancing hygiene management.

In the food manufacturing industry, hygiene management based on HACCP (Hazard Analysis and Critical Control Points) has become mandatory, and measures to prevent foreign matter contamination have become a critical issue. In particular, the contamination of dust and foreign substances in the air during the manufacturing process not only compromises product quality but also poses a risk of losing corporate trust. This handbook supports the reduction of foreign matter contamination risks in food manufacturing by introducing an overview of HACCP, its relevance to air quality, and the features and case studies of industrial air cleaners that help improve air quality. Let’s aim for a balance between HACCP compliance and improving the working environment with this material. 【Usage Scenarios】 - Food factories - Packaging processes - Weighing rooms - Pre-cleanroom areas 【Benefits of Implementation】 - Improvement in hygiene management quality - Reduction of foreign matter contamination risks - Enhancement of the working environment - Strengthening of HACCP compliance - No need for extensive facility construction

In the manufacturing industry, working in high-temperature environments and health risks from dust and odors are significant challenges. Heatstroke not only jeopardizes the health of workers but also leads to decreased productivity and increased risk of workplace accidents.

Our "Environmental Improvement × Employee Health Measures Implementation Case Handbook" highlights the importance of improving air quality and provides specific case studies, which can also aid in heatstroke prevention. 【Usage Scenarios】 - Factories with a lot of work in high-temperature environments - Manufacturing sites where dust and odors are likely to occur - Companies looking to strengthen employee health management 【Benefits of Implementation】 - Reduction of heatstroke risk - Improvement in work efficiency - Maintenance of employee health - Enhancement of the company's image

In the construction industry, dust generated during work can negatively impact the health of workers. Particularly during cutting, grinding, and demolition tasks, large amounts of dust are likely to be produced, increasing the risk of respiratory diseases and health issues. To protect the health of employees and ensure a safe working environment, dust control measures are essential. Our free handbook explains the importance of improving air quality, specific case studies of measures taken, and the clean solution FS70. 【Usage Scenarios】 - Office at construction sites - Break areas for workers - Work areas prone to dust generation 【Benefits of Implementation】 - Reduces health risks for workers - Improves work efficiency - Enhances the company's image

Dust in manufacturing sites causes many problems, including reduced yield, health issues for workers, and the occurrence of mold and unpleasant odors. In particular, closing off the site for heatstroke prevention further deteriorates the air environment, making countermeasures essential. 【Do you have any of these concerns?】 ◆ Operating air conditioning for heatstroke prevention has made ventilation difficult on-site ◆ Want to improve product yield affected by dust generated from polishing and blasting ◆ Want to improve the environment of workstations and site offices near areas prone to dust inflow ◆ Considering an environment close to a clean room but want to keep costs to a minimum Our 'FS70' is an air purifier designed for manufacturing sites that can capture dust particles smaller than 25μm, effectively collecting even invisible airborne dust with long residence times through internal air circulation. No installation work is required, and it can be used immediately. It maintains an airflow capacity of 3,000m³ per hour, covering an area the size of a tennis court with just one 'FS70' unit! Maintenance, including filter replacement, is responsibly handled by the manufacturer. *In our case studies, we widely introduce benefits such as improvements in yield rates, work environments, and mold occurrence suppression. Please take a look at the <Download Catalog>.

We are currently offering a free gift of the "Environmental Improvement × Employee Health Measures Implementation Case Handbook," which summarizes the benefits of purifying the air in work environments and provides case studies of its implementation. In cases where management categories for work environment measurements indicate that improvements are needed, there are instances where the introduction of air purifiers for factories has led to improvements. For environments where it is not possible to enhance ventilation systems or where further expansion cannot be done due to building aging, there are air purifiers that can be used without construction. One unit can cover an area equivalent to a tennis court (approximately 200 square meters). 【For those with the following concerns】 ◆ I want to improve the air environment and protect employee health. ◆ I want to capture dust and mold generated during the disassembly and cleaning of machines and air conditioners. ◆ I want to enhance the ventilation capacity of existing buildings. ◆ I want to eliminate dust and odors that flow into the office adjacent to the factory. *The handbook is currently available for free! For more details, please check by downloading the catalog.

We have decided to take on a new business that requires air blowing processes, and we have been troubled by the challenge of dust adhesion. We were introduced to the movable and easily transportable "FS 70." Although the work is basically done in fixed locations, we decided to implement it because it can accommodate future layout changes and we heard about dust control examples from other companies. Currently, we are air blowing new delivery boxes, and black plastic shavings are being collected by the air purifier. Since these delivery boxes are primarily used in clean areas, they are not expected to get very dirty, but in the future, there is a possibility that the frequency of use will increase during the collection and air blowing of used delivery boxes.

In the process of relocating the office, we prioritized "measures against passive smoking" and "improvement of the office environment." In recent years, due to the decrease in smoking areas and the strengthening of regulations, securing indoor smoking spaces has become difficult, and we have been exploring methods with minimal construction burden. At the same time that we achieved a reduction in commuting time and an increase in productivity, the smell after smoking has almost disappeared, alleviating discomfort for non-smokers. Additionally, the open structure with transparent glass and no doors has made communication possible through the smoking cabin (smoking booth). As a result, a comfortable and balanced environment has been established for both smokers and non-smokers. "By providing a smoking space within the office, it has become easier for both smokers and non-smokers to work. The issue of odor has been resolved, and productivity has improved. Satisfaction is above 10 out of 10, truly a product worth 12 or 15 points." *For more details, please download the PDF or feel free to contact us.*

With the office relocation accompanying the business expansion, the balance between a vibrant employee "smoking environment" and "productivity" has become an urgent issue. The "loss of time due to movement" and "limitations on usage time" from using the shared smoking area in the building have become factors hindering the company's speedy operations, leading to the introduction of clean air Scandinavian smoking cabins (smoking booths) that can be installed within the office. A very positive aspect is that the smell does not leak outside. Non-smoking members have also praised that they no longer smell tobacco from smokers, and having a smoking booth in the office does not have any negative impact. The most significant benefit of the introduction has been the revitalization of communication, transcending departmental boundaries and reducing the risk of information leakage. The maintenance response is quick, and the support system is solid, which is a great help. If asked whether I would recommend this product to friends or business partners, I would undoubtedly give it a perfect score of 10 out of 10. It allows us to not worry about time or smell while also enhancing communication within the company. We truly believe that it was a great decision to implement this product.

In manufacturing sites, airborne dust not only poses health risks to employees but also causes equipment failures, such as with air conditioning systems, and leads to product defects, necessitating permanent measures. The "FS70" offers a factory air purifier that can be installed without construction and captures 99% of airborne dust that cannot be removed by dust collectors. When aiming to improve air quality, are you troubled by the burdens of construction, noise, and processing capacity? The "FS70" introduced in this document operates at approximately 58dB of noise.

- It can be used immediately without the need for construction. - It comes with casters, allowing for flexible layout changes in the future. As the aging of the dust collector progresses, I was thinking, "Is there a way to change our approach and clean the air throughout the factory?" Changes after installation The first thing I noticed after installation was that the air was different the moment I entered the factory the morning after it was set up. It may be subjective, but the air felt lighter and clearer. The FS70 has been running continuously for 24 hours since the day it was delivered, and I felt the same change when I entered the factory after the holiday. "I felt a difference not only in the grinding dust and metal powder but also in the dust and odors. I think this change is something only those who enter and exit the factory every day can truly understand."

At MONday Apart Premium Kyoto Station Kamogawa and Premium Apart MONday Kyoto Gojō, we have introduced a smoking booth for two people, the "QleanAir SF 2000X," which has successfully mitigated the risks of smoking in guest rooms and improved customer satisfaction. There are losses incurred when smoking occurs in non-smoking rooms. If the smell of cigarettes lingers, it can take time to deodorize, and there are cases where the room must be taken off the market for several days. This resulted in significant opportunity loss directly affecting room occupancy rates. By sharing product sizes and requirements from the architectural design stage, we were able to secure installation space without difficulty and implement it smoothly without disrupting the flow of the area. Additionally, the established regular maintenance system provided reassurance. Since the work is carried out with prior notice, it has been completed each time without impacting our guests and has not hindered daily operations. Despite having smoking booths installed in the facility, we have received no complaints from non-smoking guests regarding "concerns about the smell" or "concerns about smoke." This has contributed to creating a comfortable space for both smokers and non-smokers.

In the case study, we are advancing the development of high-insulation structure jacket heaters. The special insulation material used has excellent thermal insulation performance, but it also has the characteristic of generating very fine dust during cutting. Workers have reported serious health issues such as "itchy eyes," "scratchy throat," and "tingling in the arms," making it urgent to create an environment where employees can work safely and comfortably. It has been demonstrated that the fine dust specific to the new material can sufficiently meet the performance standards required by our company.

Background and Issues: Measures Against Dust Generated in the Shot Blast Process "Shot blasting," one of our main processes, involves spraying abrasive materials like iron powder at high speeds onto metal surfaces to roughen them. This process constantly generates fine metal dust. In a workspace of approximately 700 square meters, 14 to 15 employees are engaged in work, but the impact of dust has been a long-standing concern. The situation was particularly severe during the summer. When workers sweat, the dispersed fine iron dust can adhere to their skin, leading to rusting and yellowing. Even with thick masks, the dust is capable of penetrating shirts and reaching the skin, raising concerns that it might be unknowingly inhaled. Ensuring the health of employees and a safe working environment is a challenge that, as a business owner, cannot be overlooked.

The customers of this store are primarily in their 30s to 40s, especially women, creating a space where diverse usage scenarios intersect. On weekdays, the main clientele consists of working individuals, but on weekends, students visit with reference books in hand to study, and groups of women gather to enjoy conversations, resulting in a coexistence of customers with various needs. Additionally, there is an event space on the second floor that can host seminars and workshops for up to 30 to 40 people, and a wide range of food and drinks, from light snacks like bread to various beverages and alcohol, is offered. Because of this diverse usage environment, it was essential to balance the convenience of smokers with the comfort of non-smokers. In the expansive space of 150 seats, with 50 seats on the basement level and 100 seats on the second floor, each having distinct characteristics, this "perfect separation of smoking" was a prerequisite for maintaining the brand experience. In this project, Clean Air Scandinavia has been involved since the early stages of store planning, allowing for discussions that consider both spatial design and the smoking separation environment. This has enabled the optimal implementation of solutions that align with the overall concept of the facility, rather than being an afterthought.

This is a case study on the introduction of the industrial air purifier "QleanAir FS70" at Tochigi Seiko Co., Ltd. At the company's Oyama factory, fine powder dust generated during the annealing process of stainless steel pipes had been a long-standing issue. To address airborne dust that traditional local dust collection could not resolve, three units of "QleanAir FS70" were introduced after preliminary measurements with a demonstration unit. After the introduction, the previously hazy white environment on the shop floor was significantly improved, creating a clean space that workers were hardly aware of. Additionally, the robust regular maintenance support system, conducted every six months, has eliminated operational burdens and dissatisfaction on-site, earning high trust and satisfaction. **Main Benefits of Introduction** - Efficient collection and removal of fine powder dust in the annealing process - Improvement of visibility within the factory and ensuring the health and safety of employees - Verification of effectiveness based on data and secure operation through comprehensive regular maintenance Businesses considering dust and work environment improvements in metal processing and heat treatment sites are encouraged to review the details.
