How Does the Electric Screw Compressor Work?

The electric compressor is integrated into a machine’s, vehicle’s or vessel’s electric and cooling systems.

  1. Electricity from the battery is led to the electric compressor’s integrated electric motor.
  2. The electric motor drives the compressor, generating compressed air.
  3. The machine’s, vehicle’s, or vessel’s cooling system keeps the compressor in optimal operating temperature.
  4. The electric screw compressor can operate continuously, 24/7, as long as the battery has sufficient charge.
