Flashback Arrestors are designed for medium flow applications and are used to prevent flashbacks in oxy/fuel systems.

The safety contained within the flashback arrestor are dependent upon the type of arrestor:

  1. A sintered flame arresting element (FA) cools the flame to below the ignition temperature of the gas or gas mixture and prevents flashback.
  2. A non-return valve is to prevent reverse flow of gases (NV) and ensures the gas only flows in one direction.
  3. A thermal cut off device (TV) closes automatically at certain temperatures and cuts off the gas flow long before ignition temperature of the gas mixture is reached.
