• ASME AG-1 Qualified • Listed on U.S. Army Qualified Products List (QPL) • UL 586 Qualified • NQA-1 Quality Assurance Program The AAF AstroCel I Nuclear Grade HEPA filter is designed to meet all the requirements of ASME AG-1 and ASME N509 and is available in Standard and High Capacity flow models. Qualified options and combinations of materials available include: AstroCel I Standard and High Capacity Nuclear Grade HEPA Filters operate on the interception-diffusion principle to remove ultra fine particles from ventilation and process air using a high media to face area ratio by limiting air velocity through the media to 5 feet per minute at rated airflow. The high density filtering media of sub-micron glass fibers is folded into a closely pleated pack with pleats evenly spaced by corrugated separators which support the media and allow minimum resistance to airflow. The media pack is sealed into the filter case sides with urethane adhesive. The case sides have rigid double box flanges (#14 Gauge Stainless Steel) or rabbited and double nailed corners (3/4" Fire-Retardant Plywood) for maximum resistance to rough handling and distortion. Neoprene gaskets with interlocking dovetailed corners or a channel containing silicone gel are provided on one or both (gasket only) faces for leak free sealing into housings or banks. Faceguards of 4x4 hardware cloth galvanized (standard) or Type 304 stainless steel (optional) on both faces for media protection and added protection from racking are provided. These filters are qualified under UL Standard 586 and are so labeled. Each filter is factory tested at 100% of rated airflow and at 20% of rated airflow (125 CFM and larger) and individually labeled and identified with a unique serial number and test results for penetration and resistance. The characteristics of the media and construction of the media pack allow the filter to be installed with airflow in either direction, regardless of the direction tested. #14 Ga.
