User Guide for Hiring Cylinders

All our cylinders and tanks are very simple to use. By following these simple instructions you should be able to use the cylinders effectively and safely. If you still have trouble, please give us a call and we will do what we can to help. Latex balloons will stay afloat with helium for around 8-12 hours. Foil balloons will stay afloat for around 2-5 days.

1. Helium CylinderN10, N20, and N30 cylinders all have gauges on the side of the filling head. This should be in the green or very close to it on receipt of the cylinder. Filling capacities are approximate and depend very much on the user inflating the balloons to the correct size, having a tight seal when inflating the balloons and turning off the cylinder when not in use. Please see our filling capacity charts.

Push Nozzle
To attach the filling nozzle simply push it onto the gas outlet until it clicks. If using a screw-in nozzle, screw it in as tight as you can by hand. There is no need to tighten with a spanner. The filling nozzle will be either a tilt-nozzle or a push-nozzle. The tilt-nozzle is best for foil balloons and latex balloons without valves. The push-nozzle is best for latex balloons fitted with valves but can also be used with un-valved balloons.
3. Opening the tap on the cylinderOnce the nozzle is attached, open the cylinder by turning the tap at the back anti-clockwise. You should hear a 'pop'. You do not have to turn the tap any further. If you hear a loud hissing noise, the nozzle is not fitted correctly. Close the tap and fit the nozzle again.

Test they cylinder by tilting or pushing the nozzle. If using a tilt-nozzle tilt the flexible tip at the 'shoulder' closest to the tip where it becomes fatter. Bending the nozzle closer to the cylinder may damage it. The more you push or tilt the nozzle, the faster the helium is released. Start by releasing the helium slowly until you get used to it, particularly when using balloons with valves fitted, as filling them too quickly can cause the end of the valve to 'pop' out.
5. Fit the balloon onto the filling nozzle ensuring there is a tight seal between the balloon (or valve) and the filling nozzle.

6. To inflate the balloons, simply tilt or push the nozzle, whilst ensuring a tight seal is maintained. Start slowly until you get the hang of it, then you can increase the speed as you feel more comfortable.

7. Opening the tap on the cylinderWhen all the balloons have been inflated, close the helium tap at the back of the cylinder. When removing the filling nozzle, ensure the cylinder is turned off, then 'bleed' the helium out of the nozzle until it stops hissing. Remove the nozzle by pulling on the roughened collar around the neck of the nozzle.
8. Store the cylinder upright in a safe place where it cannot fall and keep away from direct heat.
