Engine Cooling Fans



Our MP4 Mixed flow engine cooling fans optimise high performance with low power consumption. They are manufactured from cast aluminium alloy and have non-stall performance, non-overloading power characteristics, and low noise emission levels. The backward inclined impeller blades are particularly suited for use in dusty conditions in that the blades remain clean, thus avoiding loss of efficiency. With any fan application, the geometry of the individual installation can influence final performance; the details shown here represent results achieved when tested to BS 848 conditions. Of compact, robust construction and manufactured to meet the requirements of government defence equipment specifications, these units are especially suitable for military vehicle engine-cooling applications. Depending on the complexity of the installation, mounting methods can be adapted to suit individual requirements. With hydraulic, belt or shaft drive options, the MP4 range has the flexibility to solve virtually any specific engine-cooling problem.

True mixed flow fan designs, such as the Airtechnology Group MP4 type, provide integrators with both axial and centrifugal air discharge options from the same fan within a more compact package. This is in contrast to alternate fan types, such as pseudo mixed flow, axial or centrifugal fans. These fan types often have more restrictive installation limitations — for example, how close any obstruction can be to the fan outlet. This is not a problem for a true mixed flow fan.
