Models 76E-UF and 76E-AF flame arresters are engineered to inhibit flame propagation in gas piping systems and protect low-pressure tanks containing flammable liquids. Designed for critical industrial safety applications, the new models help safeguard low-flashpoint liquids from external ignition sources while improving operational reliability and fire protection. The Models 76E-UF and 76E-AF combine robust construction with advanced flame arrester element geometry that maximizes flame quenching capability while minimizing pressure drop. Their bi-directional design protects systems regardless of flow direction or ignition source location, offering greater installation flexibility across a range of industrial processes. The flame arresters are available in connection sizes from 2 to 12 in. 150# ASME, with DIN bolting options available. Standard housing options include carbon steel and stainless steel; flame elements are constructed from premium 316 stainless steel for enhanced corrosion resistance, and removable element housing simplifies inspection and servicing. Model 76E-AF is available with ATEX Certification in compliance with EN ISO 16852:2016. Built for applications involving flammable vapors and gases, the Models 76E-UF and 76E-AF are suitable for use with gases having MESG ≥ 0.90 mm, including IEC IIA and NEC D gas groups. Their spiral-wound, crimped ribbon flame element construction delivers dependable performance in harsh environments where safety and uptime are critical. — Groth Corp., Stafford, Tex.
