DEFLAGRATION FLAME ARRESTER / FLAME CHECK
Model 7622B is designed to prevent flashback in small lines carrying flammable gases. They are often used in small pilot lines and are intended for use where the gas flow can be shut off. The units are union type fittings with FNPT connections.
FEATURES & BENEFITS
• Flame element has sufficient openings to provide a minimum pressure drop and still prevent flashback in the line
• Flame element consists of mesh and chemically etched plates
• Modular design allows easy access for inspection and maintenance
OPTIONS
• Special options available
• FNPT threaded connections
