The gas room is situated next door to the shop making it convenient to have your cylinders filled and pay for your gas.

The fills are made via Haskell boosters, with a range of gasses available from argon, nitrox, oxygen and trimix all filled to 300 bar if required.

If we are not too busy we will pump all gasses while you wait, and if we are busy, we have over 100,000 litres of double filtered air stored in banks, which means less queuing for you, the customer.

 

Our gas and air prices are very competitive and if you are a member of the centre you even get a further reduction off air fills by 20% that’s for just being a member of NDAC.

We always strive at the centre to offer you a competitive and accurate range of mixes by our fully trained and qualified staff.

We have also had a state of the art helium analyser so you no longer have to dump the valuable helium based gas in your cylinders in order to allow someone else to "partial pressure cascade". We don't have to mathematically work out your helium and oxygen mixes. We have two oxygen analysers on-line at any one time, and trimix and heliair are physically analysed to +/- 1% accuracy.

The centre has also invested in a brand new state of the art Hamworthy Premiair Compressor with twelve air charging outlets, and a separate three outlet nitrox panel, again making gas fills even quicker if that’s possible.

Cylinders have test dates and are subject to regulations, if your cylinder is out of date or in poor condition we will refuse to fill it. If you need a service on your cylinder why not take it to our technicians. For details of the cylinder servicing and the other services offered by our technicians please visit our servicing page. more>

If you do not currently own a cylinder you can hire one from us (along with pretty much everything you would need to carry out a dive!). more>
