HEPA Box

Safeguarding Pharmaceutical Processes and Products

HEPA (High-Efficiency Particulate Air) boxes are indispensable components in cleanroom environments, playing a crucial role in maintaining air purity and preventing contamination. They serve as housings for HEPA filters, providing an effective means of removing airborne particulates from the air circulated within the cleanroom.

Cleanroom Air Filtration

HEPA boxes are primarily employed for cleanroom air filtration. They house HEPA filters, which capture and remove airborne particles as small as 0.3 microns with an efficiency of 99.97%. This ensures that the air circulating within the cleanroom meets stringent cleanliness standards.

Localized Filtration

HEPA boxes can be used for localized filtration in specific areas within the cleanroom that require a higher level of cleanliness. For instance, they can be placed over workstations or equipment that generate particulate matter.

Recirculation Systems

In recirculation systems, HEPA boxes continuously filter cleanroom air, capturing particles and recirculating clean air back into the environment.

Exhaust Air Treatment

HEPA boxes can also be used to treat exhaust air from cleanrooms. This is particularly important in applications where hazardous or sensitive materials are handled. HEPA filters in these boxes remove airborne contaminants from the exhaust air, preventing their release into the surrounding environment.
