Protectoseal 1" vent-line/in-line flame arrester C4951
Vent-Line / In-Line Circular Plate Flame Arrester
The Protectoseal 4951 Vent-Line / In-Line Flame Arrester is designed to be installed in open vent pipes or bleed lines from storage or processing tanks. The arresters are used to prevent the propagation of an external flame through the vent opening and into the tank. They provide maximum air-flow consistent with operating efficiency and safety. Listed by Underwriters' Laboratories (UL). Factory Mutual (FM) Approved.
When properly mounted in a open vent pipe line, the 4951 Flame Arrester allows vapors to discharge into the atmosphere and allows air to be drawn into the pipe through the flame arrester grid assembly. If an external flame source is encountered, the device prohibits passage of the flame into the tank's vapor space. They may be installed within specified distances from the end of an open vent pipe. The 1" size is listed for installation at distances up to 50' from the open end of the pipe.
