High Efficiency Air Filter
Air filter, a device to remove solid particulates including dust, pollen, and bacteria from the air. High efficiency air filters are widely used in a variety of fields and applications to improve the quality of air. For instance, the high efficiency air filters have found applications in building ventilation systems, engines of aircrafts and some factories etc.
Basically, the high efficiency air filters are provided with precise filter elements which can purify the air as required. Some special-use high efficiency air filters are designed with special filter elements which are made with different materials. For example, high efficiency air filters for buildings and aircrafts, etc, are usually equipped with foam, pleated paper or spun fiberglass filter elements. With regard to air filters for internal combustion engines and compressors, we usually use either paper, foam, or cotton filter elements, etc.
- Piston-type filter element is sealed with shell to prevent unfiltered air from bypassing filters.
- Anti-corrosion filter-element.
a) Stainless element has good structural performance and low air-flow resistance.
b) Seam welding technology is applied to improve its strength. - New matrix mixed fiber media
a) Enlarged effective area helps improve filtering efficiency, thus improving the working efficiency of our air filters.
b) Big open area can reduce drop of pressure. - Filmed and closed foam sleeve.
a) Anti chemical corrosion and anti-oil corrosion types can be available.
b) Coalesced liquid can be prevented from inflowing to ensure high filtering efficiency.
The chemical resistant end cover is bonded to media by special glue. Our high efficiency air filters are silicon-resin free and can work properly under 66℃.
Note: The air filter efficiency is based on ADF400 of CAGI standard, at a 38℃ inlet flow temperature.

Select Capacity
How to achieve the maximum capacity when the working pressure isn't 0.7Mpa? Firstly, find out the capacity from the above form, and then multiply the number by the corresponding modified coefficient of minimum inlet pressure.
Never choose air filters in accordance with pipe size. We should choose filters in line with capacity and running pressure.
