Description
Senator CM22 Variable Speed Screw Compressor 22kW 10Bar 130cfm – 560L Full Featured
Maximum Capacity In The Senator CM Series
The Senator CM22 Variable Speed Screw Compressor is a 22 kW (30 hp) rotary screw air compressor designed for demanding manufacturing, workshop and industrial applications requiring a high-volume compressed air supply.
As the largest model in the Senator CM Series, the CM22 delivers 1.92–3.68 m³/min (68–130 cfm), providing substantial capacity for facilities operating multiple pneumatic tools, machinery and production equipment.
A high-efficiency permanent magnet motor, variable speed control and direct-drive technology allow the CM22 to respond to changing compressed air demand while helping minimise unnecessary energy consumption.
Senator CM22 Compressor Features
22 kW Permanent Magnet Motor
The CM22 is powered by a high-efficiency 22 kW (30 hp) permanent magnet motor engineered to provide reliable compressed air performance for demanding industrial applications.
Combined with variable speed control, the motor can increase or decrease compressor output according to actual air requirements rather than continuously operating at maximum capacity.
Variable Speed Performance
Compressed air demand in industrial environments can change significantly throughout a production shift as machinery, pneumatic tools and processes move in and out of operation.
The CM22’s variable speed system automatically adjusts compressor output to respond to these changes.
When demand falls, compressor output can be reduced. As consumption increases, the system can increase output to provide the additional compressed air required, helping match compressed air production more closely to actual usage.
Direct-Drive Technology
The CM22 uses direct-drive technology to transfer power from the motor directly to the compressor air end.
Eliminating the conventional belt-drive arrangement helps reduce mechanical complexity, transmission losses and belt-related maintenance requirements while providing efficient power transfer.
Selectable 8 or 10 Bar Pressure
The Senator CM22 can operate at either 8 bar (116 psi) or 10 bar (145 psi).
These are not separate CM22 models. Operating pressure is electronically configured through the compressor controller and variable speed drive without requiring pulley changes or other mechanical modifications.
Integrated 4-in-1 Compressed Air Station
The CM22 combines the major components required for a compressed air system into one integrated package.
This configuration simplifies installation and reduces the floorspace required compared with installing individual compressed air components separately, making it a practical solution for facilities requiring substantial compressed air capacity.
560 Litre Air Receiver
An integrated 560 litre air receiver provides compressed air storage to support the CM22’s higher airflow capacity and demanding industrial applications.
Quiet Industrial Performance
Despite delivering up to 130 cfm, the CM22 operates at 71 dB(A) at one metre, helping reduce compressor noise within the working environment.

Up To 130 cfm Compressed Air Capacity
With a maximum free air delivery of 130 cfm (3.68 m³/min), the CM22 provides the greatest compressed air capacity in the Senator CM Series.
Its variable output range of 68–130 cfm allows compressed air production to respond to actual consumption rather than requiring the compressor to continuously operate at maximum output.
This makes the CM22 particularly suitable for facilities with substantial but changing compressed air requirements, providing capacity for peak demand while retaining the efficiency advantages of variable speed operation.
Is The Senator CM22 Right For Your Business?
The Senator CM22 is designed for larger workshops, fabrication businesses, manufacturing facilities and industrial operations requiring a high-volume compressed air supply.
As the largest model in the CM Series, it is particularly suited to applications where multiple pneumatic tools, machines or production processes may operate simultaneously.
Compared with the CM18, the CM22 increases maximum compressed air output from 101 cfm to 130 cfm, while retaining the larger 560 litre receiver.
Correct sizing remains important. A compressor should be selected according to actual airflow requirements, operating pressure and usage patterns rather than maximum capacity alone.
Find The Right Senator Screw Compressor
Selecting the correct rotary screw compressor is important for reliable performance, energy efficiency and long-term operation. Required airflow, working pressure, peak demand, operating hours and anticipated future requirements should all be considered.
