regulating valve and oil pump filter. Regulating valve promises the oil goes to the stages at
required pressure. Oil pressure can be observed from the oil pressure gauge Oil pressure
should be 4 to 10 Bar. On W32 Mariner Electric and W32 Canopy models oil pressure switch
promises the electric motor stop automatically when the oil pressure drops. W32 Petrol driven
mariner models do not have this feature. So for W32 Mariner Petrol engine driven models oil
pressure should be checked daily from the oil pressure gauge
.
It’s very important for the
compressor life.

Breather:
All piston type compressors have some compression leak through the rings into the crankcase. To prevent the
pressure built up in the crankcase, a breather
system is installed to allow the crankcase to ‘’breathe’’. For the air
compressors the crankcase is connected via tubing to the inlet from where the breathing is possible, or a breather
device is installed on the crankcase to vent the pressure from inside the crankcase.

Pistons:
1st , 2nd and 3rd stage pistons are connected to the crankshaft via connecting rods. Pistons move up & down and
compress the air inside the cylinders with the motion supplied by crankshaft . Have the pistons tested with proper
testing equipment in general overhaul periods and replace it if exceeding the tolerance limits mentioned in the parts
book.

Safety Valves:
Safety valves are installed onto the discharge line of each stage. All the safety valves are pressure tested and set
accordingly. If there is any unestimated pressure increase in the system safety valves open to vent the over pressure
and eliminate any possible damage may arise from the unestimated pressure increase. Safety Valves are set and
sealed by the manufacturer. Do not attempt to break the seal and change the settings of the safety valves. Otherwise
you may cause serious injuries or accidents may result in death.

Intake Filter:
Intake Filter is used to filter the particles in the air going into the com
pressor’ s first stage.
Inner element of the
intake filter should be replaced periodically according to the MAINTENANCE TABLE.

Filling Hoses:
There are 2 Filling hoses resistant to high pressure on the compressor after the final filter. They have necessary
equipments like Filling Valve, Yoke, Pressure Gauge , DIN Adapter on the hoses which is required to connect and
fill the SCBA cylinders. W32 Series Compressors are designed to fill 2 cylinders at a time. Number of the Filling
Hoses can be increased upon special request.
