Flame Arrestors


NAO’s Flame Arrestors are custom engineered for each deflagration application.

Detonation Arrestor units provide detonation-proof protection for vessels, stacks and storage tanks.

Our Arrestors can be installed both vertically and horizontally and in a wide range of sizes. They can be installed with or without water spray for cleaning or cooling; and can be fabricated in several different alloys.

These comprehensive flame arrestors help to protect pressure vessels, loading terminals and process flares from the serious danger of explosive gas/air mixtures entering stacks, vessels and storage tanks.

NAO manufactures other wet and dry systems to prevent air penetration and flash back in vessels, stacks and tanks. Give us a call to explain all your options.
