Oil sight glass
The oil sight glass is used to check the oil level in the compressor sump. It is essential that the oil
level is checked regularly and kept between the minimum and maximum marks. Failure to maintain
the correct oil level will result in failure of the compressor:
● If the oil level is too low, it will result in failure of the compressor due to insufficient
lubrication and overheating.
● If the oil level is too high, it is likely that the crankshaft oil seals will fail.
Oil pressure gauge and switch
A pressure gauge indicates the compressor's oil pressure. The oil pressure should normally
remain between 2 - 4 Bar when the compressor is running.
The oil pressure switch provides a signal to the control system. The compressor will be stopped
immediately in an alarm state if the compressor oil pressure is lost when the compressor is
running.
Oil drain plug
The oil drain plug is used to drain the lubricating oil from the compressor sump. Note that the oil
should be drained from the compressor when it is warm. On some systems, where accessibility is
limited, a valve and a pipe may be found instead of the drain plug.
