Speciality:
SP-20/G2;SP-30/G3,SP-40/G4
The series of filters are designed for seriously polluted general ventilation and the entrance of air control series as pre-filtration or coarse filtration.
It's processed by high-performance synthetic fiber in gradual technology.
Large dust holding capacity and low initial resistance,economical and practical and inlet side and outlet side are different.
Conforming to European DIN53438-F1 and American UL-class2
Be workable many times after washing the dust collected
Temperature resistance:100°C Instantaneous temperature:120°C
Be widely used in pleated and pocket filters.
