REGULATOR FIRST STAGE
Congratulations – and thank you – for choosing the OMS Airstream Evoque Regulator. Your
new regulator has been designed and manufactured with pride, per the most exacting
standards for quality and performance.
WARNING:
Use a clean working place to prepare your first stage properly.
The first stage converts the tank’s high pressure breathing air to an intermediate pressure
of 135~145 psi that can be handled by the second stage regulator to deliver a smooth flow
of breathing air when you inhale. The intermediate pressure air also can be used for
inflation of a BC or dry suit.
