ATI® Ultra II® Pocket Filters Are Used For HVAC Air Handling Systems And Paint Spray Booth Air Intakes & Exhaust.
Pocket filters are made with graduated denier polyester fibers. Upstream layer has large fibers with a more open structure followed by a denser layer of finer fibers for greater depth loading, excellent dust holding capacity and longer life. Downstream layer is a needled media forming a final barrier to catch dirt particles. Self-sealing media is sewn around an internal wire support frame to form a built-in gasket. Filters are sealed to prevent leaks. Self-supported pocket with high loft polyester media holds its shape at all times. Tapered pocket shape prevents adjacent pockets from touching. Pressure sensitive tack retains collected dirt particles.
