S-Series Oil-Free Rotary Scroll Compressors

S-Series
Contaminant free. Risk free. 100% Oil-free

Compressed air purity is crucial for many industry sectors, such as medical, research and biotechnology.

The new S-Series of oil-free scroll compressors from CompAir does not use any oil anywhere in the compressor and has been certified ISO 8573-1 Class 0 and silicone free, which represents the highest air quality level possible.

In addition to the fulfilment of legal requirements, the oil-free scroll technology reduces the costs of ownership by avoiding oil filter replacements, oil condensate treatment and energy to combat the pressure loss caused by filtration.

Benefits

  • 100% oil-free design
  • High reliability
  • Continuous operation, 100% duty cycle
  • Energy efficient
  • Low vibration and sound levels
  • Compact design
  • Low maintenance due to less moving parts

Design – 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 center, compressing the air into progressively smaller areas.
    • The compressed air is directed to the center discharge port of the compressor
  • Discharge pressure is accomplished during multiple stages of compression, resulting in a continuous intake suction and discharge.

Controller

The S-Series from CompAir 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.

  • NEMA 1, UL508A Labeled Panel
  • Magnetic Contactor with Overload Protection
  • 115V Control Circuit Transformer with Fusing
  • Door Mounted TOA Switch
  • Green Power On Light
  • Emergency Stop
  • Reset Button
  • Run Time Meter
  • Pressure Gauge

The optional Deluxe HMI control from CompAir 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 scroll compressor system from any computer or mobile device with internet connection.
