Polyester needle felt is the most widely used filter fabrics for normal temperature dust removal, thanks to its versatile property and high cost-effectiveness. Bonfilt’s Polyester needle felt filter fabrics is made out by long fiber scrim, and fine fiber punching on the surface, in suitable density and thickness to ensure the optimal filtration efficiency and tensile strength.

Various after treatment include water and oil resistance, anti-static, PTFE membrane, etc to meet your different working conditions.

Polyester Needle Felt Industrial Dust Pulse Filter Bag Advantages:

• Good tensile strength
• Excellent resistance to acid
• Excellent resistance to solvent
• Economical
• Continuous working temperature <135℃, surge 150℃

Disadvantage of Polyester needle felt filter fabrics:

• Polyester is easy to hydrolysis in high temperature and high humidity working conditions, there is ester group on the polyester macromolecular chain, which is easy to rift in the tough high-temperature and high-humidity conditions, this causes the degradation of the filter material and reduces the service life.
