Efficiency boost for variable speed blower
BOC Edwards Hibon, has launched a new addition to its range of pressure blower packages. The variable speed Silent Flow Plus (V-SF Plus) is the first variable speed blower to use a direct-drive hybrid permanent magnet (HPM) motor, making it more efficient than competitive blowers. It is particularly suitable for aeration systems in waste water treatment applications, allowing operators to make significant energy cost savings.
Unlike conventional induction motor and frequency inverter combinations, the HPM motor is highly efficient throughout the speed range, while the direct drive minimises transmission losses. The cantilever design means there are no motor bearings and no belt drives, significantly reducing the number of maintenance operations.
There are seven V-SF Plus models, with flow rates from 564 to 8185m3/hr and power ranges from 21 to 270kW. It is easy to install with low noise and low vibration levels. The V-SF Plus is extremely efficient and environmentally friendly, delivering 100% oil-free air and contamination-free transported gas.
