affordable prices.
Scuba diving regulators deliver air from an oxygen cylinder at a breathable
pressure while underwater. It does this in two stages - Firstly the
regulator breaks down the high pressure from inside the tank to a 'medium'
pressure, normally 140psi above ambient water pressure. - It then reduces the
medium pressure to a breathable pressure that is equal to that of the
surrounding water pressure. As you descend the air pressure increases to match
the increasing water pressure.
