Description
The Groth Model 7688 is a vertical in-line deflagration flame arrester designed to inhibit flame propagation in gas piping systems and protect low-pressure tanks containing flammable liquids. Flame arresters protect low-flash-point liquids from external ignition sources, providing greater fire protection and safety.
Unique recessed seat for superior protection
Fast, easy maintenance
Modular design that allows easy, cost-effective maintenance of the flame bank
The flame arrester element geometry maximizes flame-quenching capability while minimizing pressure drop
The proven crimped-ribbon spiral-wound flame arrester element offers reliable protection
