Weather Balloon Inflator

Our Weather Balloon Inflator allows you to inflate your weather balloon very easily. Working with unregulated high-pressure gas is very unsafe. Just cracking the valve open does not regulate pressure and can lead to serious injury. We therefore only sell weather balloon inflators with a brass gas regulator which reduces the helium tank pressure from up to 3,000 psi to just 80 psi to bring you the ultimate safety.

Our Weather Balloon Inflator also comes with a 2,000 gram launch scale so you can verify you have just the right amount of helium in your balloon to accomplish your mission before tying it off. The brass gas regulator will screw into any standard helium tank (CGA-580 fitting). The gas regulator includes a rubber O-ring seal which allows you to create a hand-tight seal without the need for any tools.

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.
