Enardo™ Flame & Detonation Arrestors

Enardo™ offers a wide variety of flame and detonation arrestor products with maximum flow to pressure drop characteristics. The portfolio includes in-line, free vent, deflagration and detonation flame arrestors. Enardo flame arrestors use spiral wound, crimped-metal ribbon flame cell elements to inhibit flame propagation by absorbing and dissipating heat. Connection sizes range from 3/4 inch up to 36 inches.
