Enardo Free Vent Flame Arrestors (FVFA) are designed to allow free venting in combination with flame protection for vertical vent applications. These arrestors are installed at the top of an atmospheric vent line or storage tank. They are typically used for end-of-the-line applications when the system operating pressure is near atmospheric levels and when there is minimal probability of a flame stabilizing on the flame arrestor element for an extended period.
