In-Line Flame Arrestor


ENARDO Series 7 In-Line Flame Arrestors are designed to stop the propagation of confined low-pressure deflagrations. The Series 7 is typically used for end-of-line and near 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 arrestor element for an extended period.
