This Medium BOC cylinder will provide you with the helium gas you need to easily fill your balloons and perfect your display. It is a mid-range cylinder that will inflate approximately 400 10” latex balloons.
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 – so if you’re going to be using latex balloons then you should only inflate them just before the event to make the most of their inflation-life.
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.
