HVAC Filter
HVAC Filter materials are combined from waterproof filter glass ,repeat filter paper and wave aluminum-frame materials, characterized in having a great tension and toughness, capable of resisting the passage of strong winds, and preventing the filter materials from being broken. Filtration efficiency can be 99.97% (DOP tested at 0.03 μm.) Frame materials are zinc-plated steel boards or aluminum alloys.
