Scroll Compression Explained

  • An orbiting (rotating) scroll and fixed scroll housing are mated to create the compression chambers
  •  The continual movement of the orbiting scroll moves atmospheric air from the intake toward the centre, compressing the air into progressively smaller areas
  • The compressed air is directed to the centre discharge port of the compressor
  • Discharge pressure is accomplished during multiple stages of compression, resulting in a continuous intake suction and discharge




Everything under control

The S-Series is available with different controller options. The Simplex versions can be either equipped with the basic relay panel or optionally with the Deluxe HMI electronic controller. The optional Deluxe HMI control from Gardner Denver has easy to use navigation and friendly graphics that deliver interactive and intuitive information at your fingertips.  With a built in integral webserver, via ModBus TCP Ethernet connection, these controllers provide visibility to the EnviroAire Scroll compressor system from any computer or mobile device with internet connection.
