 This series of filters is 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 the nonflammability standard and classification of European DIN53438-F1 and the United States UL900-Class2

By adding glue to strengthen the hardness and ensure its dust holding capacity and structure, anti-extrusion

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
