About Combustion Air Flash Cells
Stop Flashbacks Without Sacrificing Airflow
Combustion air flash cells, also known as firebox flame arrestors, are a passive, low-maintenance safety measure, designed to protect air inlets in fired appliances rather than the process lines that flame arrestors and detonation arrestors guard from more extreme flashbacks. Flash cells aren’t designed to withstand detonations, but they do an excellent job of dissipating heat with minimal pressure drops while still allowing large volumes of air into the system.
Our combustion air flash cells are made of either aluminum or 304L stainless steel, and they work by using a spiral wound crimped ribbon to quench the flame front before it passes through the flash cell. This safety measure means that fired equipment can be used in places with a hazardous electrical area classification.
Still Not Sure?
Do You Need a Combustion Air Flash Cell?
You should have a combustion air flash cell when your fired equipment is in a hazardous electrical area, you’re concerned about flame propagation at the air inlet, or you have legacy fired equipment that needs to be retrofitted and upgraded.
If you have a combustion air flash cell, but it is showing any signs of damage or wear such as corrosion, pitting, blockages, warping and heat damage, or audible changes in air flow, or if it is having trouble passing maintenance evaluations, you need a new one immediately.
