Synthetic Pocket air filters for AHU


Introduction:

The glass fiber pre filter consist of frame and filter media, frame can be galvanized steel, aluminum alloy, or stainless steel, and corrugated paper and so on. Stainless steel frame can be used in high acid and high alkali environment, also high temperature. The corrugated frame is a economic choice because consider the pre filters change frequently, stainless steel frame is not compulsive for every occasion, the cheaper corrugated frame is a better choice.

The glass fiber pre filters are mainly used in high temperature ovens, or painting room. Normally, the pre filters media is synthetic with cotton, those media cannot stand high temperature, but long glass fiber can bear high temperature, so this media is used in high temp situations. For painting room, the long glass fiber can absorb painting particles, the fluffy construction can make more painting particles enter the filter space, to absorb more particles and the same time let air pass through the filter.

Galvanized steel frame is the most common construction for second pocket filters, at the first, galvanized steel frame is cheaper than aluminum alloy frame, pocket filters should be replaced frequently, so choose economic product is necessary; also the galvanized steel frame is very strong so it won`t shake and broken when installing and applying. Our pocket filters use the new art craft, each part of the frame is connected by dieless clinching; 16 gauge galvanized steel frame is anti-rust, can be used in moist environment.
The thickness of galvanized steel frame is 21mm, max length can be 1.2m;
