Calloni Flashback Arrestor

This propane flashback arrestor is a critical safety component designed to protect both the user and gas equipment during operation. When installed, it prevents propane gas from travelling back up the supply line and stops a flame from propagating into hoses, regulators, or connected equipment.

By incorporating a flashback arrestor into the gas system, an additional layer of protection is provided to reduce the risk of fire, explosion, and personal injury, as well as damage to surrounding buildings, materials, and plant.

Flashback arrestors are commonly used in oxy-fuel welding and cutting applications and are equally suitable for propane-fuelled roofing and waterproofing equipment. The unit typically combines a non-return valve, ensuring gas flows in one direction only, with a flame arresting element that extinguishes and cools a flame below the ignition temperature of the gas, preventing flashback.
