Air Filter Holding Frame
Product Overview
A Holding Frame is the structural mounting component for installing HEPA / ULPA filters in HVAC ducts, cleanroom ceilings, or air handling units. It provides precise filter positioning, airtight sealing, and ease of future replacement. Compatible with three sealing mechanisms — gel seal, gasket, or knife-edge — and available in aluminum alloy, stainless steel SUS304/316, or galvanized steel. Fully customizable to match on-site duct dimensions, efficiency grade, temperature / humidity conditions, and chemical exposure.
