Gearbox Cooling Fans

AMETEK Airtechnology Group specialises in the design and manufacture of direct drive fan / impeller units used for engine and gearbox oil cooling. Our fans are designed specifically to suit customers space envelope whilst achiving the performance requirements. Our Fans/Impellers take either an axial, centrifugal or mixed flow form (combination of axial & centrifugal). In addition to the fan, static guide vanes are often supplied to boost performance together with carbon / kevlar composite ducting to optimse aerodynamic flow and safely contain the fan in a blade-off scenario. Fans are typically driven directly by the engine transmission or by using a hydraulic system. A splined sheer neck drive connects the drive and fan and is designed to fail at a given torque to limit damage should the main transmission seize.
