HEPA box, also called filter housing, is the ideal terminal filter device for air conditioning systems requiring purification to meet the cleanroom level. It can provide a desired static pressure before airing the HEPA, thus making the air outlet uniformity. With the DOP test detection system, the HEPA can provide leakage detection on site.

One-piece bending design combined with only one side welding line ensures excellent leak-proof performance.

Airflow pipe can be connected directly through top access or side access with either circular or rectangular inlet.
