Primary bag air filter, also called pocket air filter,is made of three parts: the filter frame, sewn-in pockets and pocket rings, and it is commonly used in the first or second stage of the filtration system.
Primary bag air filters can be designed in various sizes and also can be produced with various pockets or bags. Because of its special design, it can offer more than five times surface area than flat filter. A multilayered, melt-blown polypropylene medium is used to make the individual pockets. To ensure that the air flow is distributed evenly across the entire filter, pockets are made to inflate and stay apart from one another.
Primary filters are intended to catch floatable particles larger than 5 microns. While it is possible for the primary filter to capture what the pre-filter captures, doing so would significantly decrease the efficiency and efficacy in capturing the tiny airborne particles. This pocket type filter will not be distorted, or twisted when used normally, thereby extending the service life of the product. Every pocket is fully sealed, so it can avoid any dust or air leaks.
Advantages
Longer service life due to low initial pressure drop.
Widely available in a variety of sizes, pocket counts, and pocket materials.
For varied purposes, there are many different and broad filtering efficiencies available.
Simple to use, maintain, and take away.
Air filter paper
Air filter paper is applied to the air filter of automobile's engine. It will filtrate the dust and impurities when the air goes through media to enter in engine. Therefore, its filtration function keeps the engine full of clean air and protects it from the damage of impurities.
In order to get ideal filtration effect, the choosing of better performance filter media is significant. Our filter media possesses characteristics of higher filtration efficiency and longer using lifetime, cellulose and synthetic fiber can be added in the materials. Attitude determines altitude, to establish stable and longterm relationship with customers is our unchanged principle.

compressed air filter
1). Separator filter (HF9)
For bulk liquid removal plus a 3 micron coalescer (5ppm w/w maximum remaining oil content)
Two-stage filtration
* First stage: two stainless steel orifice tubes provide 10 micron mechanical separation
* Second stage: in-depth fiber media captures solid and liquid particles to 3 micron
2). Air line filter (HF7)
For removal of liquid water and oil; removes solid particles to 1 micron (1.0 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two-stage filtration
* Firt stage: captures larger particles with alternate layers of fiber media and media screen
* Second stage: coalesces aerosols and captures solid particles with multiple layers of epoxy bonded, blended fiber media
3). High efficiency oil removal filter (HF5)
For coalescing fine water and oil aerosols; removes solid particles to 0.01 micron (0.01 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two stage filtration
* First stage: multiple layers of bonded, blended fiber media for fine coalescence
* Second stage: multiple layers of bonded, blended fiber media for fine coalescence

For coalescing ultra-fine oil aerosols; removes solid particles to 0.01 micron (0.001 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two stage filtration
* First stage: coated, closed cell foam sleeve acts as pre-filter and flow disperser
* Second stage: multiple layers of matrix blended fiber media for ultra-fine coalescence
Outer coated, closed cell foam sleeve
5). Oil vapor removal filter (HF1)
For removal of oil and hydrocarbon vapors normally absorbable by activated carbon; removes solid particles to 0.01 micron (0.003 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two stage filtration
* first stage: stabilized bed of finely divided carbon particles removes the majority of the oil vapor
* Second stage: multiple layers of fiber media with bonded micro fine carbon particles remove the remaining oil vapor
Multiple layers of fine media prevent particle migration
Outer coated, closed cell foam sleeve prevents fiber migration
Designed life is 1000 hours under rated conditions.
A suitable solution for. Airborne substances, viruses and other fine particles in the nanoscale range are filtered out of the air with a separation efficiency of 99.995 % and the activated charcoal filter also removes odours. The integrated CO2 sensor alerts you should additional ventilation be required.
