Series 670/6670 End-of-Line Deflagration Flame Arrester

Brand: Protectoseal Company
The Series 670/6670 Flame Arresters are designed to provide flame stopping protection for a tank’s vapor space when mounted to the end of a tank nozzle leading directly to atmosphere.

The arresters prevent a flame front generated by an unconfined deflagration occurring outside the tank from propagating into the vapor space.
Features
  • Sizes 1" through 4"
  • Listed by Underwriters Laboratories in 1" and 2” sizes
  • Suitable for use with vapors equivalent to NEC 500 Group D, IEC Group IIA
  • Vertically mounted, parallel plate-type flame arrester
  • Protects against fire
  • Minimizes pressure drop under normal operating conditions 
  • Easy inspection and maintenance
  • Factory inspected prior to shipment 
  • Available in Aluminum and Stainless Steel
