Product Overview

Exothermic Technologies Pulsefire Backpack Kit

The Pulsefire backpack kit turns your handheld flamethrower into a professional controlled burn system.

A 3.3 gallon reservoir supporting over 4 minutes of fuel means an incredibly high capacity of real-world use. (If you held the trigger nonstop, it would yield over 4 minutes of use before running empty)

The backpack is extremely manageable at only 26 lb with fuel. The slim design keeps the weight close and comfortable. This is the ultimate in controlled burn capability in a man-portable package.

Kit includes 3.3 gal tank, shoulder straps, hose assembly, hose adapter kit, adapter fitting, and user manual.

Is it Legal?


"Flamethrower ownership is generally legal in the United States without requiring any sort of background check. This is America, and freedom is something we stand for.

As the product name states, it is simply a long range torch. However, Maryland and California do have restrictions regarding such devices. The city of Warren, Michigan also prohibits possession via local ordinance."
