1) Needle punched materials for air filtration
2) 20 years reputation
3) good quality
4) 80-500 gsm/sqm

For different filtering objects and applicatapplication, these materials have three types:

1. Primary efficiency type for dust particles > 1-5μm

     Mainly used for regular dust-collection protection of big oxy generator and air
     compressor as well as primary filtration of air-conditioning systems of the industrial
     sectors like the electronics, chemicals, pharmaceuticals and automobiles.

2. Medium efficiency type for 1-5μm dust praricles
     Mainly used in ordinary industries and pubic areas

3. High efficiency type for dust particles <1-5μm
     Mainly used in dust-free , purifying shops in the optoelectronics, LCD manufacturing ,
    biomedicine , precision instrument, foodstuff & beverage and PCB industries.
