BelGAS FM flame arrestors (photo) stop ignited vapors from traveling backward into a vent line or tank, preventing explosions, burns and other hazards. The flame arrestor product line includes critical safety equipment, such as burner arrestors, inline arrestors, stack arrestors and vent arrestors. A key differentiator of these flame arrestors is a faceplate with a pressed and sealed sight glass, rather than one that is welded or held in place with a lock nut. This eliminates seams and gaps, reduces the chance of leaks and better withstands equipment vibration. — Marsh Bellofram Group of Companies, Newell, W. Va.
