The Turbo Air® 3000 Centrifugal Compressor Compressor Handbook

The Turbo Air 3000 Centrifugal Compressor Operator’s Manual
2. The auxiliary pump, operating in tandem with the main oil pump, restores normal system oil
pressure and the compressor continues to operate.
3. A continued decrease in oil pressure initiates a trip condition and the Vantage control system shuts
down the main drive motor.
4. Similarly, if the oil temperature exceeds predetermined set points, the Vantage control system
activates an alarm condition or shuts down the compressor, depending on conditions.
Operational Guidelines
To obtain the best and safest operation of the Turbo Air Compressor, apply the following guidelines
and recommendations.
Oil Pump Operation
Cooper Turbocompressor recommends keeping the auxiliary oil pump in continuous operation (even
during compressor shutdown) to ensure proper lubrication at all times. However, in order for this
recommendation to be followed, the oil pump must be electrically isolated from all other compressor
systems.
In instances when for some reason the oil pump is not kept in continuous operation, it should be kept
running for a minimum of 30 minutes after compressor shutdown. This will assure that any excess heat
will be removed from the bearings and gearing.

CAUTION:
Always maintain the proper air supply pressure to the reservoir vent ejector/filter system
whenever the oil pump is in operation. Failure to do so may cause oil leaks, premature wear,
and component damage.
