Principle of Operation And Structure of HEPA Box

Importance of HEPA Box

HEPA Box is the terminal filtration device of cleanroom air supply system. It's main function is to transport the purified air to the Clean Room with uniform speed and good airflow organization, effectively filtering the dust particles in the air to ensure that the air quality in the clean room meets the corresponding cleanliness level requirements, such as in the pharmaceutical workshop, electronic chip manufacturing workshop and other places with very high requirements for environmental cleanliness, the HEPA Filter Box is able to provide clean air to meet the requirements of the production process. HEPA Box can provide clean air to satisfy the production process.

HEPA Box Working Principle

Outside air first passes through the primary and secondary filtration equipment of the air conditioning system to remove larger particles of dust and impurities. The pre-treated air then enters the static pressure box of the Box Fan and HEPA Filter. In the static pressure box, the air's velocity is adjusted for a more even pressure distribution. Next, the air passes through the high-efficiency filter, where tiny dust particles are adsorbed and filtered by the filter paper, and the clean air is then uniformly transported to the Clean Room through the diffuser plate, forming a stable and clean airflow environment.
