Stanbroil Liquid Propane Fire Pits 1/2 inch Air Mixer Valve, 100% Solid Brass High Capacity 90K BTU

You need the Air Mixer when you using liquid propane or some other combustible gas for outdoor fire or fire pit. The liquid propane can not burn very well without the air, so in this time you need the air mixer to mix the liquid propane and the air to make fire burning well. We have different numerical value of BTU to choose. I think our Stanbroil Air Mixer will help to burn the fire well.
