Flame Retardant Ceiling Filter

Features
  • 100% capture rate of dust particles larger than 10μm by glue treatment;
  • Step by step encryption of filter fibers and stratified filtration;
  • High dust holding capacity and long service life;
  • Stable structure, uniform air permeability, enabling uniform diffusion of airflow;
  • Low initial resistance, strong elasticity and wrinkle resistance;
  • Fire resistance treatment, flame retardant level up to S2 level;
  • Silicone free.
Applications
It is mainly used for spray system and paint booth with strict fire protection requirements.
