Flame retardant filter media is imported flame retardant fiber, step by step encryption, increasing structure, carding network hot air fusion produced. It is mainly used for pre-filtration of air filter equipment in strict working environments and air ventilation equipment.

 Product Usage 
It is suitable for working environment and air ventilation equipment with strict fire protection requirements and is widely used in the filtration of ventilation and air conditioning systems of subways, high-speed trains, high-speed railways, etc.


· with high dust capacity, low resistance and stable performance;

· silicone-free and resistant to chemicals such as chemical solvents and acid smog;

· long service life, multiple-use after vacuuming or cleaning, economical and practical;

· fire protection in accordance with the European standard DIN53438; In accordance with the German standard for flame retardant din5510-2, up to S4 level.
· It is made of imported flame-retardant polyester fiber (PET) material with high performance, high strength, high elasticity and resistance to breakage, which is fused by hot air after combing;
· In an incremental structure, the density of the fiber layer in the direction of the pure air gradually increases, and it is filtered by stages, which greatly improves the filtration performance and dust holding capacity, and extends the service life;
