About your SR307 supplied-air regulator:
What is it?
A supplied-air regulator is the intermediate
connection between a continuous-flow air
supply and a face-piece or headpiece, such as a
respirator or hood.
How does it work?
Clean air from a remote source (such as a
compressor or pump) is fed into the regulator,
which is worn on the user’s waist. After moving
through the regulator, the air then continues
into a face piece or head piece, such as a mask,
hood or helmet, allowing the user to breathe the
continuous flow of clean air. The regulator is
fitted with a control valve that allows the user to
adjust the air flow to the mask or hood.
In addition, the regulator is fitted with an extra
outlet for a spray gun or other air-driven tool.
A warning whistle is also fitted to the regulator,
letting the user know if the air supply drops
below a safe level.
Breathing air hose
The supply hose must be certified for breathing
air. The most important qualities are:
•
Odourless
•
Kink and tangle proof
•
Passing pull tests and pressure tests
•
Fitted with connectors that cannot be
connected to non-breathing air
