Basic division:
 
 
Deflagration flame arresters are intended to block and extinguish deflagration i.e. subsonic spreading of flame without shock wave. Whereas detonation flame arresters prevent detonation with the shock wave, spreading at supersonic speed.

Adast detonation arresters are intended for stable detonation.
