available on all Polar Air compressors. A variable

speed drive or VSD regulates amp draw during

start-up and motor speed during operation

according to air demand.

All Polar Air compressors are equipped with a

VSD compliant motor, ventilated electrical box &

adequate space in compressor cabinet for easy

installation. The electronic controller (PLC) for

the compressor unit provides start/stop command

and display fault status for the VSD device.
