In addition to our range balloons, we also sell disposable helium tanks. Useful when you want to fill your balloons with helium yourself. This tank has a helium fill valve to fill the balloons. The disposable helium tanks are for single-use but reclosable and therefor also handy when you want to fill only a few balloons, but intend to use the tank for multiple occasions.
Helium is non-flammable and non-toxic and the gas is stored under high pressure (about 200 bar) in steel or aluminum cylinders. For saftey these cylinders have to be placed against a solid object. The use of the cylinders or the filling of the balloons needs to be done by adults only.
Make sure you let the helium cylinder valve open so than it can be compressed more easily.
