We sell inspirators, similar to a burner on a turkey fryer, you dial in the oxygen mix created by the venturi built into the inspirator to maximize BTU’s. Each Inspirator will feed up to 22 nozzles (Tips), generating roughly 18,800 BTU’s or around 850 BTU’s per nozzle (Tip). Our products are designed to be used with standard NPT pipe fittings, our tips are 3/8” NPT while the Inspirator is 1.25” NPT.
