What size tank fits this harness?
The harness is designed for up to 20 lb CO₂ siphon tanks. For mobile use, we recommend 10–20 lb tanks. Larger tanks (50 lb) are too heavy for comfortable mobile use — use those for fixed installations instead.
What's a siphon tube tank?
A siphon tube (or dip tube) tank has an internal tube that draws liquid CO₂ from the bottom of the tank. This is required for handheld CO₂ guns to work properly. Standard CO₂ tanks only release gas, not liquid, and won't produce the cryo effect. When ordering a tank, specify "siphon tube" or "dip tube" — any welding supply or gas distributor will know what you need.
How long does a 20 lb tank last?
Roughly 30–40 seconds of total spray time, used in 2–3 second bursts. Actual time varies based on burst duration and ambient temperature. Cold weather reduces output; warm weather increases it.
Which CO₂ guns work with this backpack?
This harness is designed for use with handheld CO₂ guns like the Frost Blaster Helix and Frost Blaster Glow. You strap the tank to your back, connect a high-pressure hose to your gun, and you're free to roam while delivering cryo blasts.
Is this safe?
CO₂ effects are safe when used properly. Never aim directly at faces at close range — maintain at least 3 meters (10 feet) from the audience in the direction of spray. The CO₂ is extremely cold (-78°C) and can cause frostbite on direct skin contact. Proper training is essential before operating CO₂ equipment.
Where do I get CO₂ tanks refilled?
Welding supply shops, beverage gas distributors, and some fire extinguisher companies refill CO₂ tanks. Specify that you need a siphon tube tank filled with food-grade CO₂.
Tank Type Matters
This harness requires a siphon tube (dip tube) CO₂ tank. The internal tube reaches to the bottom of the tank to draw liquid CO₂ when mounted vertically (valve up). Standard CO₂ tanks without a dip tube only release gas and won't produce the cryo effect.
Before the Event
Test your complete setup (harness + tank + hose + gun) before the event. Check all connections for leaks. Make sure the harness fits comfortably with a full tank — adjust straps as needed.
During Use
Use 2–3 second bursts, not continuous spray. This extends tank life and prevents valve damage from excessive pressure. Allow 5 seconds between bursts when possible.
Weight Management
A 20 lb tank weighs about 40 lbs when full (tank + CO₂). For extended use, consider a 10 lb tank for less fatigue. You can always swap tanks during a break.
Tank Safety
Never open the tank valve until the hose is securely connected to your CO₂ gun. After use, close the tank valve before disconnecting. Store tanks upright in a cool, dry place away from heat sources.
Audience Safety
Maintain at least 10 feet (3 meters) between the spray direction and the audience. The cryo effect looks impressive from a distance — there's no need to get close. Never aim at faces.
