Detonation / Flame Arrestors

Typical NAO inline flame arrestors.  NAO produces flame arrestors from 1/2" diameter to large wall type multi-grid units, e.g. 17 -- 34" grids for automobile manufacturer paint booth.  NAO also can provide water cooled hydrogen burner type arrestors.  NAO produces many special units and does complete proof testing.

Cut away of inline flame arrestor -- NAO unique unitized arrestor grid.  NAO uses a vacuum furnace to fuse the stainless steel or high alloy grid into one piece -- thus eliminating expansion and contraction that can distort and allow the small grid to open.
