The aquaPAC is a simple, robust, lightweight self contained instant action oxygen delivery system, which allows the user to give immediate oxygen resuscitation or therapy to treat the diver who is suspected of suffering from decompression.

It has been designed for maximum mobility. The demand valve and gas cylinder are housed in a strong PVC covered nylon fabric case, coloured in a distinctive blue with day-yellow panels, complete with handles and shoulder string. The case incorporates "Velcro" fastenings for easy foolproof opening. For added safety the gas cylinder is retained in the case by a sleeve.
