What is a clean room?

What is a clean room?

Control the wind shape and airflow distribution within a certain range! Trivia about painting booths and clean rooms.

A clean room refers to a space where airborne microscopic particles and microorganisms are managed to be below a specified cleanliness level. It is designed to remove materials, chemicals, water, and other impurities, as well as to prevent the introduction of waste. Microparticles cannot be completely removed by standard air conditioning air filters. Therefore, during the design phase of a clean room, various measures are taken to prevent the intrusion of microparticles and bacteria from the outside and to avoid their generation within the clean room. Our company proposes the design and construction of clean rooms with specified cleanliness levels tailored to the purpose and application.

How clean does a clean room get?

How clean does a clean room get?

Particles of 0.1μm or larger in the air per cubic meter are the standard! Our company conducts cleanliness measurements after construction.

The level of clean air is referred to as cleanliness (class), and it is commonly expressed as the number of particles contained in a unit volume. The standards for air cleanliness in clean rooms have transitioned to the internationally unified ISO standards. According to ISO standards, the reference is based on particles of 0.1μm or larger per cubic meter of air, and classes are categorized from ISO Class 1 to 9. The class that we particularly receive requests for is Class 10,000, which is the standard required for general factories and inspection processes in clean rooms. Additionally, we can accommodate requests for Class 100,000 to 10,000, or, depending on the conditions, even Class 1,000. *For more details, please refer to the PDF document or feel free to contact us.*

[Clean Room Case] Mobile Clean Room

Cleaning only the main parts! Introducing a case study where significant cost reductions were achieved.

We received a request to clean the plastic molding machine. While it is possible to place the entire molding machine inside a clean room, we proposed a "clean booth" since it would be sufficient to clean only the main parts of the machine. By targeting a single machine rather than the entire factory and further converting part of it into a clean booth, we were able to significantly reduce costs. The results met the specified requirements, so we can confidently present this to the client's clients. We also have specifications for similar equipment that can achieve Class 10000 with temperature and humidity control. Please feel free to consult us at any time. *For more details, please refer to the PDF materials or feel free to contact us.*

[Construction Example] Installation of a Simple Clean Room for Company N in the Large Parts Manufacturing Industry

[Construction Example] Installation of a Simple Clean Room for Company N in the Large Parts Manufacturing Industry

Construction period is 2 to 3 days! Cleanroom level, shape, etc. are custom-designed and constructed.

At Company N, a large parts manufacturing company, there were multiple processing machines at the time, and the factory was constantly filled with invisible polishing powder, mist, and dust. As a result, during critical finishing processes (such as mirror finishing and glass material processing), these particles became the cause of fine scratches, leading to significant complaint costs. To address this, a simple cleanroom was installed. It was much more cost-effective compared to an actual cleanroom, and the installation took only 2 to 3 days, which did not affect the factory's operations. Consequently, the issue of finishing surface complaints was resolved, and we received very positive feedback from the site. [Case Summary] ■ Challenges - The factory was constantly filled with invisible polishing powder, mist, and dust. - These particles caused fine scratches during processing, resulting in significant complaint costs. - There were no funds for construction costs, and there was no downtime for the machines. ■ Results - The installation took only 2 to 3 days, so there was no impact on factory operations. - The issue of finishing surface complaints was resolved. *For more details, please refer to the PDF document or feel free to contact us.
