replaced in every general overhaul period. Replacement of the valves can be made by ALKIN Service
Personnel or a trained costumer.

Breather:
All piston type machines have some compression leak through the rings into the crankcase. There is a
breather system to prevent the pressure built up in the crankcase. In the air compressor the crankcase is
connected to the inlet with a cupper pipe from where the breathing is made possible.

Pistons:
1
st
, 2
nd
and 3
rd
stg. 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 them if exceeding the tolerance limits
mentioned in parts list or having a visible fault.

Safety Valves:
Safety valves are found at the end of each stage of compressor unit. All the safety valves are subject to
pressure tests and working pressure are set accordingly. Therefore the safety valves prevent the danger in case
of rising pressure in the compressor. 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. Check the safety valves in every general overhaul against leakages, by using a
foam water, and replace if necessary. Return the old safety valves back to the manufacturer.

1.6.2 Major Components – System
Subbase:
This is the part carrying the motor and compressor and has been supported with 4 vibration mounts.
Filling System:
The system consists of filling hoses resistant to high pressure on the compressor after the final filter; purifier,
filling valve, yoke, pressure gauge, and DIN Adapter on the hoses which is required to connect and fill the
SCBA cylinders. The number of filling hoses can be increased upon request.
