Case Study 3 – Booster Fan


The company’s booster fan carries a high volume of abrasive particulate in the gas stream. Because this is a large, single width, single inlet fan, the velocity of the particulate erodes the casing cut-off point and its surrounding scroll area.


Robinson designed, manufactured and installed a new pie-shaped cut-off area that can be easily changed out with a spare. This cut-off is a small area in the scroll that is separate from the removable pie that enables the rotor to be removed.


Due to this extra removable part in the housing, the customer now can change this piece in a one-day planned outage. The worn part can therefore be repaired at a reasonable price to become his spare.
