CLF series frequency controlled screw compressor

Special Feature:

By adjusting the airend speed utilising frequency regulation not only adjusts the output (FAD) but can also adjust the pressure (bar). The CLF machines can therefore operate at 8, 10 or 13 bar pressure without compromising free air delivered. To regulate a normal 13 bar compressor to 8 bar reduces the pressure but the output remains at the 13 bar design figure. The direct driven CLF, utilises frequency regulation in order to maximise FAD output whether at 8, 10 or 13 bar!

CLF series

Direct coupled, without v-belt or gearbox, reduces transmission losses to a minimum.
The BOGE CLF series combines a direct coupled drive system with frequency control to provide the ultimate compressor for pressure control under variable output requirements.

The CLF series operates the airend within its optimum range and by changing the speed of both motor and rotor the compressed air output adapts to the actual demand. Expensive idling times and motor switches are avoided. At the same time a tighter pressure band can be set, also helping to save energy.
