Flame Arrestor Assemblies

Our highly-engineered custom sintered porous metal assemblies are a popular choice for flame arrestors as they allow precise gas flow control while providing a mechanically sound media to quench the flame front.  Sintered porous metal flame arrestors provide a cost effective solution for high volume devices, especially for applications that require the prevention of a flame in the event that an intense explosion occurs.  Our flame arrestors are also compliant with ATEX, FM, UL, CSA, and other standards and directives.
