Aluminum Alloy Frame G3-G5 Pre-Filtration Air Filter

The primary filter is a primary filtration of the air conditioning system and is used to filter dust particles above 5 microns. Polyester fibers or nylon nets are used as filter media and are folded into high-strength die-cut cardboard. Dust particles in the air are caught between the pleats and pleats by the filter material, and clean air flows out from the other side.
The primary filter is mainly used for pre-filtering of central air conditioning and centralized ventilation systems, pre-filtering of large air compressors, clean air return systems, pre-filtering of local high-efficiency filtration devices, home central air conditioning, nuclear industry and defense industries for special purposes.

Main Features

1) Corrosion resistance, high temperature resistance;

2) Low resistance, large wind power, long service life;

3) The folding design increases the filter area of the filter and the dust holding capacity increases;

4) The filter medium is made of high quality polyester synthetic fiber, which can be used repeatedly for cleaning, long service life and cost saving.

Optional specifications

Note: The following is the common size of the primary air filter. Youjie can also provide customized size air filters according to your requirements.

Structure: The two-layer die cut cardboard or aluminum alloy frame

combines with the filter media to form the simple and strong structure. Meanwhile, the filter adopts a V-shape pleated structure, the material usage is three times greater than common air filter, so the dust holding capacity is greater.

Filter paper: Special blended by non-woven fabrics and synthetic fibers with a fluffy structure, large dust holding capacity and low initial resistance

Filter media: The filter media is closely combined with the protection grid and processed into a contour, equal spacing filter pleat layer by special process, allowing the air to pass freely and evenly, so that the dust can be uniformly adsorbed on the entire media, thereby achieving high dust holding capacity.

Protection grid: The grid is a galvanized grid or wire grid to increase the strength of the filter pleats, effectively weakens the pleat jitter during use, thereby reducing secondary pollution.

Cardboard frame: High-strength waterproof cardboard, each intersection and the filter media are closely connected, which enhances the filter's robustness and helps to maintain the flatness of the pleated filter media and the balance of the pleat spacing.

Aluminum alloy frame: 1.00mm thick aluminum profile enhanced by double-sided or single-sided galvanized protection grid support, can be repeatedly cleaned.
