Description

Our filter media rolls are offered in different sizes, thicknesses, and filtration grades to suit various air filtration systems. They can be tailored to fit specific needs and applications. The rolls and pads are specially designed to efficiently trap dust particles and have a large capacity to retain them, without releasing any fibers into the airflow.

Adopting high-performance, high-strength anti-breakage polyester fiber, step by step encryption, carding mesh hot air production; has a high dust capacity, low resistance, flame retardant characteristics; does not contain silicone, able to resist such as chemical solvents, acidic fumes and other chemical substances; sustained resistance to temperature of 100 ℃, instantaneous resistance to temperature of 120 ℃; filtration object ≥ 5 μm particles of dust and all kinds of suspended matter; coil or sheet, according to customer requirements Stamped into round, oval and other specifications.

  • Large Filtration area
  • Grade: G1-G4
  • Content static electricity fiber
  • Resistant to fractures and highly elastic
  • The filter material fibers are progressively denser from blue (air inlet side) to white (air outlet side), enabling layered filtration
