The air filter produced by our company is divided into six categories according to the characteristics of purification efficiency:（Level of efficiency of air filters in accordance with national standards under rated air volume）

1、Primary filter: for ≥5 micron particles, filtration efficiency 80>E≥20, initial resistance ≤50 Pa

2、Medium effect filter: for ≥1 micron particles, filtration efficiency 70>E≥20, initial resistance ≤80 Pa

3、High efficiency filter: for ≥1 micron particles, filtration efficiency 99>E≥70, initial resistance ≤100 Pa

4、Subfilter: for ≥0.5 micron particles, filtration efficiency E≥95, initial resistance ≤120 Pa

5、Filter: for ≥0.5 micron particles, filtration efficiency E≥99.99, initial resistance ≤220 Pa

6、Over filter: for ≥0.1 micron particles, filtration efficiency E≥99.999, initial resistance ≤280 Pa

Widely used in general ventilation general ventilation system, central air conditioning unit, clean workshop, clean workshop, laboratory and clean room, or dustproof for electronic and mechanical communication equipment.

? the filter cartridge produced by our company is divided into three categories according to the characteristics of filter selection:

I. Wood pulp fiber paper filter cartridge:

High-quality and high-efficiency wood pulp fiber materials from the United States and Western Europe are 1. selected, which not only have small pore size, large air permeability, low resistance and high efficiency, but also have large filtration area.

2. adopt advanced folding new technology, the interval is uniform.

Both the end cover of the 3. filter tube and the inner and outer protective net adopt high quality electrochemical plate, which not only has good strength, but also has better anti-rust and anticorrosion performance.

4. low hardness and high strength closed hole foaming rubber sealing ring is different.

5. adhesive from Henkel, will not produce degumming and cracking phenomenon. 

Scope of application: gas turbine, centrifugal air compressor and other large units of the inlet filtration and powder coating line powder recovery system.

II. Long fiber polyester filter cartridge:

The 1. uses the synthetic high strength polyester long fiber nonwovens materials from the United States HV、 Japan Toray and other countries. The fibers are smooth and tubular, the fibers cross each other, the holes are smaller, the distribution is more uniform, and the fibers have good filtration performance.

2. the application of polyester long fiber filter material, the filter tube not only has better acid and alkali resistance, higher filtration efficiency and less running resistance. Compared with the traditional filter material, it has incomparable wear resistance, high strength and breaking resistance, pulse backblowing and other methods are easier to clear ash, and can be cleaned repeatedly by water without damaging the filter material and prolonging its service life.

3. the combination of tough and durable polyester filter material and anticorrosive steel plate mesh support structure, the new open folding design increases the effective filtration area and can make the air flow through the surface continuously and without hindrance.

4. compared with the traditional filter bag, the filter area is increased by two to three times, which reduces the pressure drop, improves the filtration efficiency and prolongs the service life.

Scope of application: steel, cement, chemical, machinery, cigarettes, pharmaceutical, nuclear power, thermal power, environmental protection and other production lines to recover raw materials, purification and dust removal.III. Membrane coated polyester filter cartridge:

PTFE resin is used as raw material in the 1.. The microporous membrane with stereoscopic network structure is made by special technology. It has small pore size, high porosity, smooth surface, waterproof, good oil resistance, very low friction coefficient and good non-viscosity. Chemical corrosion resistance, high temperature.

2. film coated filter tube has a strong and smooth surface, the surface filtration is not torn by powder particles, the possibility of wear and scratch, dust can slide regularly.

3. constant cladding filtration effect makes the air flow of the dust collector more stable, improves the utilization ratio of the powder and the purification function of the recovery effect. The surface filtration is easier to complete in an instant and improves the filtration efficiency.

4. domestic leading film-covered technology and TEX high-quality raw materials, Tongji University advanced testing to ensure product reliability.

Scope of application: carbon powder, metal powder, polymer powder, cement, metallurgy, food, coating, petrochemical plastics and other industrial areas of flue gas and dust particles treatment and recovery.
