Introduction of common types of air filter elements


Air filter

The air filter element is also called air filter cartridge, air filter, style, etc.. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, aseptic operating rooms and various precision operating rooms.

PP filter

PP filter is also called the PP meltblown filter, meltblown filter made of polypropylene superfine fiber tangles made of hot-melt, fiber randomly in space to form a three-dimensional porous structure, pore dimension filtrate flows along the gradient distribution in surface, deep and fine filter in one, can retain different size impurities. The precision range of the filter element is 0.5 - 100 m, and the flux is 1.5 times higher than that of the peak room filter with the same accuracy. The different types of end cap joints can be configured to meet the needs of various engineering installations.

Wirewound filter element

The textile fiber yarns with good filtration performance are carefully twisted on the porous skeleton. The yarn materials polypropylene fiber, acrylic fiber, cotton fiber. When winding the yarn by controlling the tightness of winding and dilute the density can be made over different precision filter, can effectively remove all kinds of suspended solids, liquid particles and other impurities, for a variety of liquids have a high purification effect.

Folding microporous filter element

Folding microporous filter with polypropylene (Polypropylene) thermal spraying fiber membrane, Niron (Nylonb) of polytetrafluoroethylene (PTEE) membrane precision filtering device such as a filter medium is made, with small size, large filter area and high accuracy. The range of filtration accuracy can range from 0.1 M to 60 M. Hot melt adhesive is used for the sealing of the filter head cover and the whole structure connection. Filter element joint is three kinds of international common type: 222 joint, 226 joint, flat mouth. All the products have been tested strictly before leaving the factory to ensure the stable performance of the products.

Activated carbon filter

There are two kinds of activated carbon filter products: compression type activated carbon filter, bulk activated carbon filter.

1. The compression type activated carbon filter adopts high adsorption value of coal activated carbon and coconut shell activated carbon as filter material, and the food grade binder is sintered and compressed. Compressed activated carbon filter both inside and outside are wrapped with a layer of non-woven fabric having filtering function, ensure the carbon core itself will not drop carbon powder, carbon core are arranged on both ends of the soft NBR rubber gasket, the carbon core is arranged in the filter cartridge has good sealing.

Plastic shell activated carbon particles in 2, bulk type activated carbon filter will need special, the end cover is welded on the end surface of the shell with two welding equipment, both ends of the casing are respectively put into play non-woven filter filtering effect, to ensure that the carbon core in use will not drop when carbon powder and black. According to the needs of customers, the end cover can be made of shell connection of different types. Interface methods are: flat pressure, pipe type (type: 4042, 4044, 4046, etc.).
