AstroCel I HEPA filters are used primarily in “cleanrooms” and “clean benches,” areas which require the very highest levels of contamination control. The filter consists of water-proofed, fire-retardant fiberglass media formed into a series of pleats. Corrugated sheets of aluminum separate the pleats to permit maximum usage at minimum resistance. The media is enclosed in and foam bonded to a filter frame made of aluminum or galvanized steel. Gasketing is available on the upstream, downstream or both faces.

Optional antimicrobial traps and concentrates particulate air contaminants to improve Indoor Air Quality (IAQ) while preserving the integrity of the media.
