C. Bole & Co. offers Hi-Speed Regenerative Turbine Blowers for handling air, other non-explosive gases and gas-air mixture completely oil free at low volume flow and medium pressure range.
It has a Unique working principle that it is fitted with the rotor, as the rotor rotates, the air entrapped between the rotor blades is radially and circumferentially accelerated and pushed in to the side cavity. Here it is pressurised and pushed back to the rotor blades where it is again radially and circumferentially accelerated. It will then pushed along a special path through the Impeller and side channel till it is discharged into the discharge port. Thus leaving the blade tip, the air flow around the housing contours back down to the root of the succeeding the blade where the flow pattern is repeated. The Impeller rotates with absolutely no contact between it and the casing. This means that no lubrication is required, guaranteeing 100% oil free operation. Since there is only one moving part it has got maximum operating reliability and totally maintenance free.
