Pressure Regulator for XL-15 and XL-18 Flamethrowers
This regulator allows the user to reduce and set system pressure to adjust flamethrower performance (range, flame width, fuel use rate, CO2 use rate and recoil). Without a regulator, the flamethrower’s operating pressure is equalized with the 20oz. CO2 tank. CO2 pressure largely depends on outside temperature (see below chart).
XL-15: 400 – 700 psi (depending on fuel mix / viscosity)
XL-18: 300 – 400 psi (depending on fuel mix / viscosity)
