Product Introduction:
The HEPA air supply diffuser is a terminal filtration device installed on the ceiling of cleanrooms. It consists of a plenum box, HEPA filter, and diffuser plate. The plenum box is made of steel plate with a knife-edge sealing structure, achieving true zero leakage. Due to its strong versatility, aesthetic appearance, easy installation, and simple maintenance, it is suitable for all levels of cleanrooms and widely used in purification air conditioning systems in biological, pharmaceutical, microelectronics, and other industries.

Product Features:
The plenum box is made of low-carbon steel. The HEPA filter and the plenum box are integrated into one unit. A damper is installed at the air inlet of the plenum box to adjust the air supply uniformity and static pressure effect. It is lightweight and easier to install, making it particularly suitable for use in cleanrooms with aluminum alloy T-grid (or keel) ceiling systems.
