Robbins Myers Dual Squirrel Cage Blower 208-230V 1PH 0.06HP 3350RPM 5502820
This Robbins Myers dual squirrel cage blower is a double-wheel centrifugal fan assembly built around a single centrally-mounted motor driving two squirrel cage impeller wheels — one on each side. Manufactured by Robbins Myers in Gallipolis, Ohio, this unit was produced to IBM specifications (IBM P/N 5502820) and mounts to a flat metal base plate for easy integration into equipment enclosures or HVAC systems.

Applications
Dual squirrel cage blowers of this type are used to move air through enclosed equipment cabinets, computer systems, and industrial housings where a compact, low-profile footprint is required alongside reasonable airflow capacity. The dual-wheel design places one impeller on each side of a central motor, producing airflow from both ends simultaneously — a configuration well suited to long, narrow equipment enclosures. Robbins Myers was a well-established U.S. manufacturer of fractional-horsepower motors and blower assemblies, and this unit was produced to IBM's specifications for use in IBM minicomputer and peripheral equipment of the 1970s–1990s era, such as System/36, System/38, and AS/400 equipment cabinets. These blowers also see continued use in HVAC fan coil units, electronics cooling enclosures, and industrial control panels where their compact dual-discharge design is an advantage. Replacements and spares for IBM-spec blowers like this remain in demand for legacy system maintenance.
This Robbins Myers dual squirrel cage blower (IBM P/N 5502820) has been visually inspected and appears to be in good used condition. It has not been powered up or tested at our facility, but it was pulled from a working environment where it was previously in use. Both blower housings are intact and show normal wear consistent with prior service use. The metal base plate shows light surface oxidation typical of used industrial components. The 3-pin power connector appears intact and undamaged. Please view our photo set and contact us if you have any questions.
