End-of-Line Rectangular Plate Flame Arrester


Gas Groups: D | IIA

Protectoseal Series 860 End-of-Line Rectangular Plate Flame Arrester is installed where it is not necessary to conserve vapor losses but where low flash point liquids must be protected against fire and explosion from exterior sources of ignition. The flame arrester element is mounted to the arrester housing but is easily removable to facilitate inspection and maintenance. These flame arresters are designed to provide the maximum air flow consistent with operating efficiency, fire protection and low cost maintenance.
