Free Vent Flame Arrester

Free Vent Flame Arresters (FVFA) are designed to
allow free venting in combination with flame protection for vertical vent applications. This type product is installed at the top of an atmospheric vent line or storage tank. They prevent flame propagation by absorbing and dissipating heat using spiral wound crimped ribbon flame cells. These cells allow maximum flow with maximum protection. The FVFA is used to stop the propagation of confined and unconfined low pressure deflagrations. It prevents an ignited atmospheric vapor cloud from propagating beyond the Flame Arrester into the vent line or tank.

Description

Free Vent Flame Arresters (FVFA) are designed to
allow free venting in combination with flame protection for vertical vent applications. This type product is installed at the top of an atmospheric vent line or storage tank. They prevent flame propagation by absorbing and dissipating heat using spiral wound crimped ribbon flame cells. These cells allow maximum flow with maximum protection. The FVFA is used to stop the propagation of confined and unconfined low pressure deflagrations. It prevents an ignited atmospheric vapor cloud from propagating beyond the Flame Arrester into the vent line or tank.

FVFA’s are typically used for the end of line applications
when the system operating pressure is near atmospheric
levels and when there is minimal probability of a
flame stabilizing on the Flame Arrester element for an
extended period.

Free Vent Flame Arresters allow free venting and
flame protection for vertical vent applications. Designed with flanged connections, this arrester allows removal of the flame cell element without their removal of the venting assembly. Standard housing construction is aluminum, carbon steel, and stainless steel element is available in aluminum or stainless steel. Special material and protective coatings are available on request.
