FILTERS & AIR PURITY
Both compressors at Underwater Explorers use only O2 compatible grease and are run with  high quality hydrocarbon free premium synthetic lubricant imported specifically for this purpose. Our clean air runs through triple filters. We have also joined the Dorset Clean Air Charter which encompasses routine air tests by the Trading Standards to ensure the purity of our air. In association with Dorset Council, tests are run by Aquatron using precise FTIR spectroscopy - avoiding the disadvantages and poor accuracy of stain (draeger) tubes.

WHIPS
The filling system comprises of a total of 17 air, nitrox and trimix fill whips. Of these 3 are on a separate Partial Pressure Blending Panel dedicated to gas blending. There are two clean air panels with 4 fill whips each (8 in total) and a combined clean air/blending panel with 6 separate whips. Any of these fill whips can be run off the banks, either or both compressors at any given time. Pure (100%) Oxygen above 5 Bar is only run off the PP blending panel.

PARTIAL PRESSURE PANEL

All staff at Underwater Explorers are trained and certified as Advanced Gas Blenders and . The preferred option for Nitrox and Trimix blending at Underwater Explorers is the PP Blending Panel which has a triple filtered clean air inlet with 3 fill whips monitored through a high performance analogue pressure gauge as well as a precise digital gauge. Our maximum safe gas (O2 & He) filling rate is no more than 15 bar per minute (and preferably slower at times) which allows for Nitrox fills in about half an hour and trimix blends in under an hour.
