How It Works

What are flamethrowers used for?

Our products are designed for personal use and commonly used for the following

  • Ground clearing or controlled agricultural burns.
  • Ice and snow melting/clearing
  • Incinerating weeds and other unwanted ground plans.
  • Back burns and pre burn commonly used by forestry personnel for forest fire containment/prevention
  • Pyrotechnics
  • Film production and movie props. (check us out in Westworld, Quarry, Punisher, The Darkest Minds and Burger King commercials) 
How do flamethrowers work?


Flamethrowers consist of two tanks, one holding the flammable liquid mix and one for the pressurizing agent (CO2) used to propel the flammable liquid, a gun housing and an ignition system. Carbon dioxide from the CO2 tank exerts pressure on the fuel in the other tank and forces it through the fuel hose and into the gun housing. At the same time, butane or propane is used to to fuel the pilot torch located at the tip of the gun housing to maintain the flame when the flamethrower is in standby.

How it works

The flamethrower is brought into standby by igniting the pilot torch which delivers a flame to the tip of the gun housing. This creates a small flame that remains lit as long as it is supplied with fuel from the propane or butane canister.

When the trigger is pushed pressurized fuel from the fuel tank is released through the gun housing, and then ejected into the atmosphere in the form of a burning combustible stream that catches fire from the small flame at the tip of the gun.


What fuel can I use?

We design our products with freedom and flexibility, allowing for many mixture combinations. This freedom allows our customers to concoct unique mixtures tailored to their specific application.
For best results, we recommend starting with a 90% diesel and 10% gasoline mix. If you are using our fuel thickener, 50% diesel and 50% gasoline with 1 scoop of thickener per gallon is a good place to start. Napalm available here.

What is the fuel capacity?

Approximately 3.3 gallons (12.5 liters)

Can I use pressurized air instead of CO2?

Although theoretically compressed air could work, we recommend against it because it is not as safe, more cumbersome, and difficult to reach the same pressures. Using compressed air would require hardware modifications which would void the warranty.

A few reasons CO2 is optimal:

  • It’s cheap and commonly available. Extra CO2 tanks are available allowing for a quick swap to repressurise a new tank.
  • It is extremely stable and liquefies at a low pressure which makes it ideal for getting consistent pressure from a small, light and portable 20oz tank.
  • The biggest safety benefit of CO2 is in the chemistry. CO2 is an inert gas. Where there is carbon dioxide fire is impossible, so as you shoot your flamethrower the empty space in the fuel tank is replaced with CO2, completely eliminating the chance of internal fire.
Do I need batteries?

Nope, no need to worry about keeping batteries charged. Our flamethrowers are electronic free like all full size flamethrowers. 

  • Reliability: When designing a dependable flamethrower, we focused on minimizing the   amount of moving parts. An electronic free system eliminates the hassle of dealing with underpowered fuel pumps and solenoids that can easily clog and fail when using thickened fuels. 

  • Waterproof: No need to worry about getting caught in the rain with your flamethrower. We designed our flamethrowers with freedom in mind, environmental factors shouldn’t stop you from throwing flames.
  • Safety: LiPo batteries are hazardous, risky and delicate. Mixing up wires, overcharging, moisture exposure, a puncture, using the wrong charger, low voltage, sunlight or high temperatures can cause fires and spontaneous combustion. The combination of these batteries and fuels like gasoline pose a serious risk.

We encourage users to be smart and to never jeopardize anyone’s safety. Beware of flamethrowers that uses LiPo battery operated fuel pumps to pressurize highly flammable liquid. Beware of flamethrowers that have vented fuel tanks and/or oxygen in those fuel tanks. Lingering flammable vapor exposed to sparks from batteries, electric fuel pump etc. creates a very dangerous combination.

Can I upgrade my X15 to the new XL18?

Yes, we do plan to offer an X15 flamethrower “upgrade program” for existing X15 owners. This would convert the X15 into the new XL18 flamethrower. More details will be announced in the coming weeks.

How should I maintain my flamethrower?

Our flamethrowers are designed for regular use and to be generally maintenance-free.

How should I store my flamethrower?

You should store your flamethrower depressurized and with the fuel tank empty. Please store your device out of the weather and in a secure area away from pets, children, and any other unauthorized users.


Are Flamethowers Legal In My Area?

United States

Are Flamethrowers Legal?

Yes. In the United States, flamethrowers are federally unregulated tools and not considered a firearm by the BATF. No need for any NFA tax stamps, licensing or even an FFL dealer. However, it’s the purchaser’s responsibility to ascertain that ownership and or use does not violate any state or local laws or regulations.

Sorry, no shipping to Maryland. Maryland’s fire code prohibits flamethrower ownership.

Yes, we do ship to California. Units sent are modified with a smaller nozzle to be considered California compliant versions, meaning that the range of the device will be less than 10 feet.

California users please read California Health and Safety Codes 12750, 12751, 12760, 12761 and ensure compliance before changing a tip that would produce a range over 10 feet.

According to California Health and Safety Code 12750(a) “Flamethrowing device” means any non-stationary and transportable device designed or intended to emit or propel a burning stream of combustible or flammable liquid a distance of at least 10 feet.

For an unmodified version, please contact us with proof of valid permits before ordering


Yes, we do ship to Canada. Flamethrowers are legal in Canada, they are not considered a firearm nor a weapon and they are not a prohibited item.

Our products are specifically designed for personal use for the following; ground clearing or controlled agricultural burns, ice melting/clearing, incinerating weeds and other unwanted ground plans, “back burns” or “pre burns” for forestry use and forest fire containment/prevention, or for the use in film production and movie props.

Other Countries

Flamethrowers are legal and unregulated in most counties. Chances are, we can ship to you. 

We have done our best to check laws in most countries. Ultimately, you are responsible for ensuring the possession and/or use of flamethrowers is permitted in your jurisdiction. Before ordering, we encourage you to make sure you are operating within accordance of all applicable laws and regulations.


How long does shipping take?

We hold inventory on all of our flamethrowers and accessories so most in-stock orders are shipped within 24 hours.

US orders are shipped via USPS Priority Mail (1–3 Business Days) . Once your order is shipped, a tracking number will automatically be sent to your email.  Shipping speeds can be adjusted at checkout.
