MODEL 7698

In-line Horizontal – ATEX Certified

The Groth Model 7698 is an In-Line Horizontal Deflagration Flame Arrester designed to inhibit flame propagation in gas piping systems and to protect low pressure tanks containing flammable liquids. Arresters protect low flash point liquids from external sources of ignition. This provides increased fire protection and safety.


• Horizontal installation
• Eccentric design minimizes liquid accumulation
• Flame arrester element geometry maximizes flame quenching capability while minimizing pressure drop
• Spiral-wound, crimped ribbon flame element
• Modular design allows easy and cost-effective flame bank maintenance
