‘OM-9400’ Oil Monitor.
The ‘OM-9400’ Oil Monitor provides a means of ensuring that there is sufficient oil in the Pump during normal
Compressor Unit operation. It contains a Micro-switch which registers the level of the oil in the Pump. Should the
level of the oil drop below a preset level, the Micro-switch will open, causing the Unit to shut off.
The Oil Monitor is an electrical device, and requires 120 or 230 volts to operate. On Units where the voltage is
460 or 575, a Step-down Transformer or alternate power source must be provided by a Licensed Electrician. The
Electrician must ensure that the wiring of the Monitor(s) meet with all applicable codes and regulations.
Please be advised that, in some instances, the Level Indicator may read as ‘Low’ on the Monitor. This is
acceptable. Please test the Monitor regularly to ensure it is functioning correctly.
Beltguard Aftercooler.
A Beltguard Aftercooler is used to decrease the temperature of the compressed air after it exits the Compressor
Pump and before it enters the Tank. The compressed air is cooled as it passes through the ‘radiator style’
Aftercooler. The air flow created by the Pump Flywheel provides the cooling action.
Specifications.
Die cast aluminum case.
Internal brass float registers oil level.
Lens allows viewing of oil level.
Suitable for use with voltages up to 230 v ac.

Maintenance.
Test the Monitor on a regular basis to ensure it
is working properly.
