Weather Balloon Inflator

Rocketman Weather Balloon Inflator

Safely and efficiently inflate your weather balloon with our professional-grade inflator, designed for high-altitude balloon launches. The built-in regulator reduces helium tank pressure from 3,000 psi to 80 psi, preventing over-inflation and ensuring controlled fills. A built-in gas filter protects your balloon from dust and impurities, while the kink-resistant air hose is rated for extreme temperatures from -40 °F to 140 °F, making it reliable in any launch environment.

Key Features:

• Hand-Tight Connection: No wrench required—quick, easy setup.

• Tank Pressure Gauge: Monitor helium pressure at a glance.

• Pressure Regulator: Reduces helium from 3,000 psi to 80 psi for safe inflation.

• Gas Seal: Rubber cylinder mate seal for leak-free operation.

• Inflation Tubing: 5 ft PVC tubing (option for 10 ft) accommodates any balloon size; longer hoses allow the helium tank to remain on the ground or farther from the launch site.

• All-Brass Fittings: Durable gas fittings for long-term reliability.

• Built-In Filter: Prevents contaminants from entering the balloon.

• Kink-Resistant Hose: 3/8″ tubing designed for easy handling and consistent flow.

• CGA-580 Fitting: Compatible with standard helium tanks.

Customizable Hose Length: Choose between 5 ft or 10 ft hoses to suit your launch setup.

Our Weather Balloon Inflator combines precision engineering, safety, and convenience, ensuring every high-altitude balloon launch is controlled, reliable, and efficient.

Here’s how we recommend filling your weather balloons:

1. Attach the inflation system to your helium gas cylinder, a hand tight seal will be more than adequate, as brutal force with a wrench could damage the seals.
2. Insert the inflation system nozzle into your weather balloon’s neck. Do not unroll the weather balloon yet. It is much easier to work with the balloon’s neck when the balloon is still rolled up.
3. Secure the weather balloon to the inflation system nozzle. Wrap both the neck of the balloon and the bottom of the inflation nozzle together with electrical tape.
4. Unroll the balloon and prepare it for inflation. Before you start to inflate your weather balloon, have your helper hold the balloon loosely over their forearms.
5. Slowly open the valve on your helium gas cylinder to begin inflating your balloon.
6. Let the balloon lift itself out of your helpers' forearms. Eventually the balloon will rise out of your helper’s arms. You can now start measuring your balloon’s lift.
7. Inflate your balloon until it has the right amount of lift. When measuring your balloon’s lift, make sure there is slack in the inflation hose. You want all of the balloon’s lift to be pulling up on the scale, not the inflation hose. You want all of the balloon’s lift to be pulling up on the scale, not the inflation hose. Don’t forget to add the weight of the inflation nozzle to the reading on the scale. The inflation nozzle weighs 200 grams, so if your scale measures a lift of 800 grams, your balloon is actually generating 1,000 grams of lift (measurement on scale plus the weight of the inflation nozzle).
8. Once your balloon has the right amount of lift, shut off the supply of helium.
