High Pressure Centrifugal Blower

Most industrial ventilation and process air systems operate at low to moderate static pressure. That is manageable to handle for a standard centrifugal fan. But some facilities need high pressure compared to this. Fluidized bed combustion reactors, high backpressure industrial burner systems, glass melting furnaces, long pneumatic conveying lines and high-pressure-based air supply systems demand high static pressure. A standard centrifugal fan is not suitable for this operation. When a standard centrifugal fan is operating beyond its maximum peak pressure, it enters an unstable operation zone, like surging, increasing vibration and delivering inconsistent airflow. This process becomes unreliable, the unit loses sustainability and rises in abnormal electricity consumption.

The High-Pressure Centrifugal Blower is exactly designed for this condition. Based on some principles, it maintains sustained high static pressure. It can generate more pressure per rotation by increasing impeller speed and using a design optimized for high static pressure. Increasing blade tip speed can increase pressure as well; the more speed, the more pressure will be generated. Another important thing is a perfect scroll housing; its precision-machined scroll housing and optimized volute profile are chosen precisely for high static pressure. Those components work together to generate and maintain a stable static pressure without any surging. The result is keeping consistent pressure under any system resistance.

The High-Pressure Centrifugal Fan offers moderated airflow at high static pressure. Maximum peak efficiency can vary by design of its narrower impeller geometry and operating point. It may have different efficiency characteristics than standard centrifugal fans. One of the important things is that the blower has a chance of overloading. So, engineers need to be more careful about service factors while choosing a motor. It is a suitable choice for those industrial facilities that need more pressure than a standard centrifugal fan.
