Enardo Detonation Flame Arrestors provide protection against flame propagation in piping systems that are manifolded or have long run-up distances. The design is unique with larger flame channels that limit plugging and make cleaning easier. These arrestors are bi-directional and are proven to stop an ignited flammable vapor mixture approaching from either direction and traveling at subsonic or supersonic velocities. Its flame element offers maximum flow to pressure drop characteristics.
