Product Advantages:
- Variable speed on a belt drive: the drive ratio can still be changed if the duty point moves.
- Speed follows demand instead of running flat out against a load/unload band.
- Assembled and tested in our own plant; rotors from a qualified airend supplier.
- Bearings SKF or NSK, electrical components Schneider, control Siemens S7-200 SMART.
- Performance run on our test bench and noise checked in our acoustic room before dispatch.
- Test records travel with the shipment, so the numbers on this page can be checked against your unit.
