What is Industrial Clean Room (ICR) technology?

Low-Cost, Low-Energy component techniques or total engineering technologies that electronics industry requires; air cleanliness, high-precision temperature, humidity and airflow environments, and countermeasures against molecular contamination or microscopic vibration.

What is airflow control technology?

Technology to equalize cleanliness, temperature, and humidity levels in clean rooms by controlling inlet airflow with distinctive diffusing mechanisms.

Can provide solutions to these problems

  • Want to heighten equipment efficiency and paint quality


With the HEPA outlet located on a section of the ceiling, the cold air exits from the ceiling through the HEPA filter and is drawn down into under the floor, without dispersion. This causes the air in the cleanroom to partially stagnate, degrading the clean level and temperature distribution in the room.
Clean Diffuser creates optimal airflow with a minimized ventilation frequency by dispersing air exiting from the HEPA outlet, which has the effect of imitating airflow distributed from across the whole surface of the ceiling.


  • Improving the air flow distribution of cleanrooms

    By diffusing the airflow in the HEPA outlet, disparities in the airflow distribution between the lower part of the outlet and areas without the outlet can be eliminated, thereby improving the airflow and temperature distribution.

  • Energy-saving

    Diffusive-type HEPA unit extends covering area, achieving air circulation reduction and so as the fan power.
