This X Large BOC cylinder provides 9.06m3 of helium gas to easily fill your balloons and perfect your display. It is the largest cylinder we provide and will inflate approximately 950 10” latex balloons – and is therefore suitable for regular use.
Our balloon gas is completely safe and can be used indoors or out as it is non-flammable, non-explosive and non-toxic.
Without valves, 12” latex balloons will last 10-12 hours when filled with helium – and therefore should be inflated with helium just before the event.
Metallic foil balloons are specially adapted to contain helium, will float for several days after inflation and can be re-inflated.
Price includes delivery and collection of cylinder and up to 2 weeks rental, with an additional weekly charge for longer rental periods.
