THE WORLD LEADER IN CLEAN AIR SOLUTIONS HEPA FILTERS The AstroCel I High Efficiency Particulate Air (HEPA) filters are the most efficient air filters commercially available. They have broad application in cleanrooms and other areas requiring the very highest levels of contamination control. • Semiconductor manufacturing • Electronics • Pharmaceutical processing • Photo film manufacturing/ processing • Hospitals • Universities • Laboratories • Food processing • Asbestos abatement AstroCel I filters are available to meet all performance classes per the Institute of Environmental Sciences & Technology (IEST) Recommended Practice (RP) IEST-RP-1-CC001. AstroCel l filters are available in a variety of construction materials and cell side configurations to fit AAF and competitive framing systems or sealing designs. Refer to the section on selection data for a complete list of options. Manufactured to the Highest Quality Standards Standard Capacity 5⅞″ deep – 125 FPM @ 1.0 in. w.g. 11½″ deep – 250 FPM @ 1.0 in. w.g. Efficiencies: 99.97% and 99.99% minimum efficiency on 0.3 micrometer particles. For ULPA and MEGA efficiencies up to 99.999995% on 0.10 to 0.20 micrometer particles, use AstroCel II LPD Series mini-pleat filters. High Capacity 24″ x 24″ x 11″ deep - 2000 CFM @ 1.4 in. w.g. Efficiencies: 99.97% and 99.99% minimum efficiency on 0.3 micrometer particles. High Capacity AstroCel I HCX filters are designed to handle higher airflow than a standard HEPA filter. This offers greater operating flexibility and cost savings. • Double the airflow of a standard capacity with only a 40% increase in resistance. • Lower resistance, lower energy cost, and longer life at the same rate

Gasketed Wood Construction 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. Particle Board 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 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. Gasketed...

Special Construction AstroCel® I Filters AstroCel l Side Access Filters AstroCel l filters are constructed with a flange at the top and bottom for installation into earlier models of AstroSeal® side access housings. The filters are available with wood or metal cell sides. Military and Nuclear Designs AstroCel I filters are available to comply with military and nuclear specifications (ASME AG-1) requiring special cell side material, radiation resistant media, rabbeted joints, special testing, and special packaging and marking. Product Information Standard AstroCel I 24″ x 24″ x 11½″ Operating...

Scan Testing Media Testing to Meet Exacting Quality Standards Leak Testing Filters that pass the overall efficiency test may still have minute pinhole leaks. AstroCel I filters can be factory scanned to assure there are no pinhole leaks. Scanning detects these leaks which are repaired before the filter is released for shipment. Every roll of media is carefully checked for a specific set of physical and performance characteristics, including: • Efficiency • Thickness Scan test showing leak indicated by a smoke trail. • Tensile Strength AAF uses a proprietary static scan test with a challenge aerosol...
