FLAME ARRESTER
The Groth Model 7661 Deflagration & Detonation Flame Arrester inhibits flame propagation in gas piping systems. The design of the Model 7661 Flame Arrester makes it ideal to protect liquid storage tanks containing NEC Group D (IEC Class IIA) gases with a Maximum Experimental Safe Gap (MESG) equal to or greater than 0.90 mm.
FEATURES & BENEFITS
Housings are available in carbon steel , stainless steel or Alloy C276 and elements in stainless steel, Alloy C276 or other corrosion resistant alloys.
These arresters are compact with high flow capacity and low pressure drop. Elements are easily removed in-line for cleaning and maintenance and are economical to replace if necessary.
OPTIONS
• Other materials available
• Sensor ports
• Large inspection and cleaning ports
• Swing bolts for fast element removal
• Factory installed thermocouples for flame sensing
