LH/AD Deflagration Flame Arrester

Brand: PROTEGO
Request Information
The Protego LH/AD end-of-line deflagration flame arrester provides protection against flame transmission through atmospheric deflagration. 

The device is typically installed on vent lines of vessels and process engineering apparatus which are not pressurized. 

For safe application it is important that an endurance burning situation can be excluded, so typically is installed on vent lines which discharge vapor for a short time period only. 

The device prevents flame transmission from atmospheric deflagration into the vessel or plant.
Features
  • Weather hood provides protection against environmental impact (Harsh weather conditions, bird nests, etc.)
  • Available in sizes DN50 (2") up to DN800 (32")
  • Easy maintenance
  • Available for elevated operating temperature
  • Protection against atmospheric deflagration
