The Enardo Series 8 High Pressure Deflagration Arrester is designed to protect against high velocity and high pressure flame fronts that have not yet reached the detonation phase of the flame, but are outside the operating range of standard flame arresters. The Series 8 deflagration extinguisher is superior to standard flame arresters in networks that feature long pipe sections with one elbow, bend, high operating pressure and long flame stabilization in the flame retardant cell.
