Glass Fiber Pre Air filter


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 paper frame is a economic choice because consider the pre filters change frequently, stainless steel frame is not compulsive for every occasion, the cheaper corrugated paper frame is a better choice.

The glass fiber pre filters are mainly used in high temperature ovens, or painting spray 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.

The glass fiber filter are made of long glass fibers, the long glass fibers are non-woven constructed and the fiber density is different from one side to other side. The air inlet side is green and the fibers are sparse, the outlet side is white and fibers are comparatively denser. This design can let the filter media capture different size dust more successfully and make full use of the media, enlarge filter service life.

This long glass fiber filters are used for removing oil, paint, dust in automobile factory painting room.
