We can fill all cylinders while you wait, be they for SCUBA, Airgun, Paintball, Confined Space or other specialist applications. At Divemaster Scuba we hold large quantities of compressed air up to 350 Bar. We bank on site 90,000 of high quality filtered breathing air at all times and can produce another 1000L every minute. Our monthly air purity tests performed by outside vendors ensure our breathing is free from contamination. For use with Oxygen situations we also offer a triple filtration process.As defined by the UK HSE the Composition of breathing air Component Concentration at atmospheric pressure
