HEPA Filters

The Aerostar® HEPA filter is constructed with an 18 gauge galvanized steel frame with a continuous band of media pleated back and forth over corrugated aluminum separators. The HEPA filter is UL Classified to meet strict fire codes, and removes a broad range of airborne contaminants, including fine dust, smoke, soot, pollen and radioactive particles. This filter contains a two-part polyurethane, which assures a positive seal of the media pack and frame. The interlocking frame design with sealant placed behind the top and bottom flange allows unobstructed air flow and ease of filter handling. The HEPA has corrugated aluminum separators that assure even pleat spacing. The hemmed edges on the aluminum separators reduce possible pleat damage. In addition, filters, 99.97% DOP and higher, are tested on our CIPAT (Computer Integrated Particulate Air Test) duct to assure compliance with overall efficiency specifications. The 99.99% HEPA’s are scan tested for leaks. HEPA filters are used in final filter applications including hospitals, electronics, nuclear, pharmaceuticals, laboratories, aerospace, food processing and optics. They can also be used as pre-filters in cleanroom environments and other critical applications for final HEPA/ULPA/SULPA filters.
