What is HEPA Filter Box?
A HEPA Filter Box, also called the HEPA filter terminal, or The HEPA Filter Terminal Housing, is a conventional method of integrating HEPA Filters into ductwork systems for high-quality clean air distribution. This terminal filtration device, featuring an inserted HEPA filter, is utilized in the construction and renovation of various class clean rooms.
HEPA, which stands for “high-efficiency particulate air [filter],” can potentially eliminate at least 99.97% of airborne particles sized 0.3 microns (µm), including dust, pollen, mold, and bacteria. A new HEPA filter typically has a pressure drop of 25 mm of water (about 0.24 kPa), and replacement is recommended when the pressure drop increases to 2–4 times this value.

Gel Seal HEPA Filter Terminal Box
Gel Seal HEPA FilteTerminal is based on the ordinary HEPA box, to increase its sealing and uniqueness. The special jelly glue is efficiently used as the sealing groove, which is nested with the knife edge around the box to form an airtight seal. It is equipped with a PAO detection port, which has the advantages of good sealing， beautiful shape， simple structure, and easy construction.

HEPA Filter Box with side flange air inlet
The “side flange air inlet” refers to the specific design feature where air enters the filter box from the side through a flange. This configuration allows for efficient and controlled air intake, ensuring that the air passing through the HEPA filter is effectively purified.

HEPA Filter Box with Air Damper
The “air damper” is a device used to control or regulate the flow of air within a ventilation or air conditioning system. In the context of a HEPA filter box, the air damper allows for the adjustment of airflow rates. It can be manually or automatically controlled to achieve the desired air circulation.
