11 kW screw compressor with Fixed Speed and VSD options.
The 11 kW single-stage screw compressor is positioned for workshops, small factories, service centres, maintenance departments, fabrication shops and general light industrial users that need dependable 10 bar compressed air.
CRS can quote this size as a practical fixed-speed machine for steady air demand or as a VSD / inverter machine where air demand changes during the day. The key single-stage ranges are the TBF fixed-speed range and the TF VSD range, with CRS confirming the correct model against pressure, duty cycle, running hours and site power supply.

Fixed Speed vs VSD
- Fixed Speed: best when air demand is stable, predictable and the machine runs close to full load.
- VSD: best when air demand rises and drops during the day, helping reduce unloaded running and wasted energy.
- CRS recommendation: choose based on actual demand profile, not only motor size.
- System support: CRS can supply the compressor, dryer, filters, receiver, drains and pipework checks.
