Description
EG&G Rotron CX33A2G Centrimax Centrifugal Blower Fan 115V 50/60Hz 3.8A 027554
The EG&G Rotron CX33A2G is a single-phase centrifugal blower from Rotron's Centrimax series. It uses a backward-curved impeller in a scroll-type volute housing to generate high-volume airflow against static pressure, making it well suited for electronics cooling, instrument enclosures, and industrial ventilation where a compact, self-contained blower is needed. Power is supplied via hardwired pigtail leads terminating in a 2-pin connector.

Applications
EG&G Rotron's Centrimax series centrifugal blowers are used extensively in military, aerospace, and industrial electronics cooling applications — environments where reliable, high-static-pressure airflow in a compact package is critical. Rotron, originally Rotron Manufacturing Company and later part of EG&G, built a long reputation supplying ruggedized fans and blowers to the U.S. military and defense electronics contractors from the 1950s onward; the Centrimax line is a well-known family in that tradition. Centrifugal blowers of this type are still used today in VME/VXI rack systems, radar and communications equipment, power electronics enclosures, medical and laboratory instruments, and general industrial ventilation where axial fans cannot overcome the required static pressure. The scroll housing allows the outlet to be directed at a specific angle, simplifying duct integration in tight enclosures.
This EG&G Rotron CX33A2G Centrimax centrifugal blower fan has been inspected and appears to be in good used condition. The housing shows minor surface scuffs and light wear consistent with previous service use. The impeller and scroll housing appear intact with no visible cracks or damage, and the motor end cap and mounting base are in good shape. The unit retains its original performance curve label on the side and rating plate on the rear motor cover. It was pulled from a working environment where it was previously in service.
