This Iwatani commercial portable butane gas stove maintains constant pressure as fuel is being consumed, providing the maximum and consistent output for the life of entire fuel canister. It also allows the stove to utilize the entire can of butane leaving no residual fuel, assuring greater economy and safety.

1.Pressure Sensing Device
Advanced regulator design shuts off the flow of butane which extinguishes the flame if the pressure in the canister rises to unsafe levels. 
The device activates at 60psi [0.4Mpa] to 90 psi [0.6Mpa]. The regulator can be reset by pushing down a lever on the regulator. Much like a circuit breaker in your home.

2.Canister Setting Safety Device
The canister cannot be attached if the stove is not in the off position. 
This feature protects against unintentional gas escaping through the burner without ignition.

3.Pressurized Receiving Guide
Two sized 0-rings are built into the receiving guide of the regulator. 
This double protection feature helps give the canister and regulator an airtight seal.

4.lnverted Drip Pan Prevention Device
This feature protects the use of the stove by not allowing the drip pan to set level when the drip pan is inverted.
