AP Valves Liftbag LB25Ci

[Pierre Farrugia]

Hello,

I am considering buying an AP Valves 25 kg liftbag with internal sealing buffle with inflation cylinder. Does anyone uses them? What are your views? Also I am not sure if I should get the 0.2L version or the 0.4L version. Anyone has a pic of both for comperison? Also anyone has some dimensions of the 0.2 and 0.4 cylinders?

I have one, without the bottle, and it's a nice bit of kit. It's very similar to their SMBs.

A 0.2 litre cylinder at 230 bar is about 45 litres air. A 0.4 litre cylinder is about 90 litres of air. But remember you will be at depth, so at 30m, you'll only get 11 litres of lift out of the smaller bottle and 22 litres out of the bigger.

How much are you looking at lifting and what depth? If you're just going to use it as an SMB then get the smaller bottle, but if you want to use it as a lifting bag I wouldn't bother with the bottle.

Laters,
Janos
