If you’re looking for the standard filters for 2000 cfm air scrubbers but want a better option, the High Capacity AstroCel I is constructed in the same fashion as the standard AstroCel I. The filter is made of water resistant, fire retardant fiberglass material formed into a pleated pattern. The material is covered in foam bonding and placed into a filter frame made of 3/4" fire retardant particle board. What is unique to this High Capacity model is a special design shallow crimp separator that enabled the space for additional filter materials. Gasketing is available on the upstream, downstream or both faces.
AstroCel HEPA filters are used primarily in “cleanroom” and other areas which require the highest levels of contaminate control. High Capacity AstroCel I filters can be used as an alternative to the standard HEPA filters to obtain higher air flow at the same resistance or for lower resistance and longer life at the same air flow capacity.
“H”-level filters are scan tested at 99.99% efficiency to insure the filter is free from pin hole leaks. AAF uses a proprietary static scan test with a challenge aerosol of non-toxic, polyfunctional alcohol. For pharmaceutical and those applications requiring PAO, AAF offers scanning with this material using a light scattering photometer.
