A standard C-Face mounted motor ensures that the motor and compressor will be properly aligned when the compressor leaves our factory… and stays that way.

The integrated mounting flange allows access for coupling maintenance. The flexible dropout coupling can be replaced without removing the motor!

A cartridge-style, triple-lip seal arrangement ensures the oil stays in and contaminants stay out.

Designed to be direct driven

with no gears or belts involved.

Intelligent Control （ continuation）

Time-delay restart to avoid starting loaded.

Control options： Continuous Run: load/unloads according to system demand without shutdown.

Auto-dual: allows compressor to shut down for energy savings.

Auto-restart: allows compressor to automatically re-energize and return to service after loss of incoming power.

Options： Pressure switch control ： the compressor can continue to run if the pressure transducer is fails.

MODBUS communication protocol ： for remote monitoring and control of compressors via RS485 network
