  • Minimum number of FLAMEFILTER discs due to the effective shock absorber
  • Quick removal and installation of the complete PROTEGO flame arrester unit and of the FLAMEFILTER discs in the cage
  • Modular flame arrester unit enables each individual FLAMEFILTER discs to be replaced and cleaned
  • Provides protection from deflagration as well as from stable and unstable detonation
  • The right angle design saves pipe elbows
  • Extended application range for higher operating temperatures and pressures
  • Minimum pressure loss
