Oil-free Scroll Compressors - Introducing the S-Series
Compressed air purity is crucial for many industry sectors, such as medical, research and biotechnology.
CompAir's new oil free S-series scroll compressor has set a new standard in compressed air delivery. Not only does this scroll compressor series meet industry standards, but this technology reduces the costs of ownership because there is no need for oil filter replacements, oil condensate treatment and energy to combat the pressure loss caused by filtration. It is 100% oil and silicone contaminant free.
• Premium 100% Certified Class 0 Oil & Silicone-Free Rotary Scroll Compressors
• Reduced cost of ownership – no oil filter, no condensate treatment, no filters
• Maximum flexibility from modular design & low maintenance due to fewer moving parts
A scroll compressor is also referred to as a spiral compressor, a scroll pump or a scroll vacuum pump. The rotary spiral scroll design creates a continual compressed air flow over multiple stages and there is no need for oil lubrication. A scroll compressed air system runs quieter and more smoothly than a reciprocating version because there are only two moving parts - a fixed scroll and an orbital scroll. Fewer parts make the scroll compressor energy efficient, highly reliable, and less prone to mechanical failure. Compared with a rotary screw compressor, a scroll compressor vibrates less and is almost noiseless.
100% oil-free design
Continuous operation, 100% duty cycle
Low vibration and sound levels
Low maintenance due to less moving parts
Simplex Models S04 - S08, with their small footprint, low noise level and vibration dampening construction, provide an efficient and oil-free smaller scale compressed air service.
Duplex Models S7D - S15D are quiet models with maximum noise volumes reaching 72db(A). The Duplex systems offer high quality, oil-free compressed air services.
Both the Simplex and Duplex models are available with the Deluxe HMI electronic controller. It is optional with Simplex but comes standard with the Duplex models. This powerful control and monitoring system gives you access to a variety of tools including alarm and fault logs, pump discharge temperature monitoring and a system capacity and operation trending meter among many others.
The multi-lingual digital controller features a 3.5” full-colour screen that offers powerful navigation tools and intuitive data displays to makes the S-Series easy to control and monitor. The Deluxe HMI controller also features an integrated web server, allowing you to monitor the system from any computer, tablet or mobile device.
With power options ranging between 4kW and 15kW, the S-Series offers the flexibility and guaranteed reliability to be suitable for a wide range of applications regardless of the conditions.
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.
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.

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.
