Product Description
The Enardo DFA Series detonation flame arrestor
represents the best value in flame arrestor protection.
The detonation flame arrestor provides protection
against flame propagation in piping systems that are
manifolded or have long run-up distances. These are
typically used for extended pipe length or multiple pipe
bend configurations to stop high pressures and flame
velocities with detonations and overdriven detonations.
It also stops confined and unconfined, low and high
pressure deflagration. The design is unique in the ability
to provide large flame channels which requires less
frequent maintenance and greater ease in cleaning
when service is required, translating to less down time.
Enardo DFA Series detonation flame arrestors are
bi-directional and proven to stop an ignited flammable
