Balloonium® Helium is lighter than air and non-flammable, therefore it is perfect for inflating party balloons. Supplied in a 10 litre Integra® cylinder at 300 bar. Integra® cylinders are safer, smaller and lighter. The Integra® cylinder is designed to be used with a choice of Integra® flow optimisers (available separately) which ensure optimum weld results whilst reducing excessive gas usage too.
