Cleanroom HEPA FILTER:

A HEPA filter is a type of air filter that is designed to capture particles as small as 0.3 microns in size with a minimum efficiency of 99.97%. HEPA filters are used in a variety of applications where clean air is essential, including in cleanrooms, hospitals, laboratories, and homes.

HEPA filters work by using a combination of three mechanisms: interception, impaction, and diffusion. Interception occurs when particles in the air stream collide with filter fibers and are trapped. Impaction occurs when larger particles are unable to avoid the fibers and are trapped due to their inertia. Diffusion occurs when small particles move erratically and are trapped by the filter fibers as they pass by.

HEPA filters are commonly made from a combination of glass fibers and other materials, which are arranged in a mat or pleated configuration to increase the filter’s surface area. The filters are typically encased in a frame or housing to facilitate installation and replacement.

In addition to their high efficiency, HEPA filters are also known for their low air flow resistance, which allows them to filter air at a high rate without restricting air flow. This makes them ideal for use in applications where a high volume of air must be filtered, such as in cleanrooms or HVAC systems.
