The media pack is thoroughly sealed to the inside of the cell sides with a variety of adhesives that prevent bypass leakage around the pack. The sealant totally encapsulates the media edges, closing off all leak paths. Pleat spacing is precisely maintained by corrugated aluminum separators that permit maximum usage of the media at minimum resistance. For corrosive environments, vinyl coated separators are available. Close-up photo shows how the polyurethane bond, standard on most AstroCel I filters, encapsulates the pack, eliminating voids. Rolled edge separators are used to minimize the risk...

AstroCel ® I Selection AstroCel l filters are available in a wide variety of standard sizes and construction materials. Special sizes can be fabricated or special materials used for unique requirements. There are twelve criteria encompassing materials and performance that go into the makeup of an AstroCel I filter. Careful selection of the right combination will result in the filter that best meets the needs of your application. Size 40 standard sizes from 8" x 8" to 36" x 72". AstroCel I filter sizes are listed with the height dimension first, followed by the width, then depth. Minimum Efficiency...

Save on New AstroCel ® I HCX Filter Installations • Fewer filters required. • Less space required for filter bank. • No transitions. • Faster installation. High Capacity AstroCel I HCX 24" x 24" x 111/2" Rated Airflow Capacity @ 1.4 in. w.g. (350 Pa) initial resistance Rated Airflow Capacity @ 1.0 in. w.g. (250 Pa) initial resistance Service Life Ratio @ 1000 CFM (1700 m3/hr.) • When operated at 1000 CFM, the filters last approximately twice as long as standard HEPA filters. HCX Initial Resistance vs Airflow Capacity • Lower energy cost. Shallow Crimp Separators Permit More Media Increased airflow...

Extend AstroCel ® I Life with Prefilters No HEPA filter installation should ever be operated without prefilters. AAF has a broader selection of prefilters than any other manufacturer – from roughing filters, to automatic roll filters, to pleated filters, to extended surface filters. AAF strongly recommends two stages of prefilters in front of HEPA filter installations. AAF tests have shown that prefilters greatly extend the life of HEPA filters. The higher the efficiency of the prefilters, the longer the life of the AstroCel I filters. MERV 15 filters can extend HEPA filter life nearly nine times....
