流機エンジニアリング List of Products and Services

A dust collector is a device that removes dust and other particles floating in the air to create clean air. It prevents dust generated within factories from being released into the surrounding area and purifies the work environment at construction sites, thereby improving working conditions. It is used for a variety of purposes, including as part of the product manufacturing process. Before placing a formal order, it is possible to conduct a practical test using a rental machine. You can verify the performance and effectiveness of the dust collector prior to its introduction. *For details about the demo, please contact us.*

• Hydraulic Equipment

Dust generated during work will be collected underneath the workbench. By suctioning dust from the work surface, it prevents dust dispersion and keeps the work area clean. The large table surface is powerfully suctioned with a downward flow of about 1m/s. The dust collection unit is placed separately, allowing for flexible layout and maintenance-free operation. As an option, installing dust-proof sheets at the work openings can generate even stronger suction power. The dust-proof sheets can also be made movable, allowing for flexible use of the workspace.

We would like to introduce a case study from Ryuki Engineering, which proposes a reduction in the running costs of water treatment. We received a request from a precision parts/plating factory that wanted to reduce costs by purifying river water for use as cleaning water for precision electronic components. [Case Study] ■ Industry: Precision parts/plating factory ■ Challenge: The factory has been using tap water for cleaning precision electronic components, but the water bills are high. They want to reduce costs by purifying river water for use as cleaning water. Our company purified the turbidity of river water to the level of tap water using "ECO Clean." By enabling the use of river water, we provided water at one-tenth the price of tap water, achieving a 90% reduction in tap water costs through purification and utilization. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study from Ryuki Engineering, which proposes a reduction in the running costs of water treatment. We received a request from a metal processing factory to efficiently recover rare metals from high-concentration rare metal-containing water (valuable material) without lowering the concentration. [Case Study] ■Industry: Metal Processing Factory ■Challenges - Previously, recovery involved four processes (solid-liquid separation, concentration, dewatering, drying), which incurred significant time and costs. - There was a desire to efficiently recover only rare metals from high-concentration rare metal-containing water (valuable material) without lowering the concentration. Our company has consolidated the process into a single machine for de-drying. This one unit handles all roles, significantly reducing installation costs, installation space, and running costs (electricity and maintenance expenses). *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study from Ryuki Engineering, which proposes a reduction in the running costs of water treatment. We received a request from a hot spring facility to purify colored groundwater containing organic matter so that it can be used, in order to reduce water utility costs. [Case Study] ■ Industry: Hot Spring Facility ■ Challenge: Reduction of water utility costs Purification of colored groundwater containing organic matter for use Our company proposed a system that combines coagulation sedimentation tanks, ECO Clean, and ozone microbubbles to achieve purification, decolorization, deodorization, and sterilization, resulting in water utility costs being halved. This generated a cost benefit of approximately 50 million yen annually, equivalent to 150,000 liters per day, or 750 baths for household use. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study from Ryuki Engineering, which proposes a reduction in the running costs of water treatment. We received a request from a food processing factory to dry and reduce the weight of their residual materials in order to cut disposal costs. 【Case Study】 ■Industry: Food Processing Factory ■Challenges - When disposing of residual materials (press cake), the disposal fee is determined by weight, leading to high costs for disposing of moisture-laden residuals. - They wanted to dry and reduce the weight of the residual materials to cut disposal costs. To further enhance the efficiency of processing the juice generated during the drying process, we proposed a combination of dewatering and ECO Clean. This not only reduced industrial waste costs but also contributed to converting the dried residuals into animal feed, generating valuable by-products. *For more details, please refer to the PDF document or feel free to contact us.

Features of the Pleated Filter in Fluid Engineering 1. **Compact** We have developed and provided filters that boast approximately 20 times the filter cloth surface area compared to conventional bag filters. This is the source of our overwhelming suction power! The amount of air that can be processed is different from other companies! 2. **Maintenance-Free** Automatic regeneration through powerful supersonic impulses prevents clogging. When releasing compressed air, a supersonic impulse (shock wave) is applied to the filter to forcefully dislodge dust particles attached to it. This significantly reduces the effort and time required for replacing and maintaining conventional bag filters. With automatic filter cleaning, clogging is less likely, allowing for continuous operation without maintenance. 3. **High Purity** The outlet cleanliness of our standard filters is below 0.1 mg/m³, achieving a high level of cleanliness equivalent to atmospheric dust levels. Furthermore, our PTFE filters designed for fine particles achieve cleanliness below 0.01 mg/m³, comparable to clean room standards, and are used in nuclear, aerospace, bio, and precision electronics fields. A high level of cleanliness equivalent to atmospheric dust levels is achieved.
