Construction Machinery

Low noise fan blade profiles - a perfect fit for Tier 4f applications

Construction machinery cooling fans have to withstand high workloads in extremely hostile conditions. They are constantly subjected to severe vibrations, high temperatures and massive accelaration forces due to changing RPM. Cooling fans are powered by hydraulic motor or directly mounted on the diesel engine and driven via belt pulley.

WingFan's axial fans are specifically designed for these operating conditions and are not only built to be robust and durable, but at the same time light and thus increase the durability of the belt and the pulley. Minimal axial blade deflection and narrow track width are further advantages of WingFan axial fans. Designed to meet the latest emissions standards (Tier 4f or above), WingFan offers axial fan solutions that are ideally suited to the high resistances while still being exceptionally quiet.

Our unparalleled BLEX® technology also makes it possible to achieve incredible noise reductions of up to 7 dB (A) by closing the gap between the blade tip and the enclosing nozzle. Specially customized axial fan solutions with electronic or bimetal viscous clutches unlock additional potential for reduced emissions. We also offer to test and optimize your entire radiator package with fan on our state-of-the-art wind tunnel, allowing you to save money and time with minimized development intervals.

Articulated Dump Truck

WingFan’s powerful and efficient S38Z and S45Y high pressure fans are the ideal solution for cooling articulated dumpers operating in the most rugged and hostile environments. Axial fans with ample pressure reserve to handle heavily fouled radiators caused by dusty conditions is crucial to prevent overheating. The S45Y is an excellent choice for a hydraulically driven reversible fan used to efficiently clean debris from a fouled cooler.

Compressor Portable

Most portable compressors use a pusher fan configuration mounted directly onto the engine crankshaft to minimize the height of the engine enclosure. Great care must be taken to select a fan capable of withstanding the severe un-dampened torsional vibration from the crankshaft being transmitted directly in to fan blades. WingFan offers a number of specially reinforced low noise blade profiles specifically developed for cooling portable compressors.


High efficiency hydraulic motor driven fans for excavators ensure the lowest possible power consumption while freeing up engine power for the main machine functions. Ever increasing noise emission restrictions on urban building sites requires carefully engineered cooling fans in combination with the cooling package shroud designs to minimize noise emissions. Our in-depth experience in selecting a fan that will meet the most challenging operating parameters can be validated by testing the fan in combination with the cooling package on our state-of-the-art wind tunnel before undertaking costly field testing of the machine.

Gen-sets Portable

Containerized gen-sets pose an extra challenge for effective cooling due to the very high resistance caused by airflow direction changes, noise attenuators and louvres on the air inlets and outlets. These portable containerized generators are often deployed in urban areas for special events such as music festivals or televised sport events where gen-set noise cannot be tolerated. WingFan can provide guidance to help configure a fan to achieve the noise and cooling targets.

Mining Dump Truck

Reliability and durability are two of the most important parameters when selecting a fan for a mining truck cooling package. WingFan offers powerful and reliable fans to guarantee sufficient cooling reserves even with heavily soiled radiator packages.


The high vibration in compactor applications call for a fan engineered to withstand the extreme stresses in vibratory rollers. The fan should also have enough pressure reserve to overcome extra resistance caused by fouled radiators in dusty environments. Our robust and quiet fans have proven themselves in many compactor and roller applications even in the hottest climates. WingFan axial fans are also suitable for hydraulic driven fans in reverse operation to clean clogged radiators.

Skid-Steer Loader

WingFan has developed a high performance one-piece fan specifically for the extremely high pressure and airflow demands in Skid-steer machines. The very limited space available for the fan requires a very high rpm to cool the machine effectively with a relatively small diameter fan. By applying BLEX® blade extensions to the tips of the blades it is possible to reduce the rpm by up to 800 rpm and still achieve the same cooling performance but with up to 6 dBA less noise.


WingFan works with many large tractor OEM’s to design small diameter space-saving fans specially adapted to the dimensions of bimetal or electronically controlled viscous clutches. Advanced CFD techniques are used to dramatically reduce noise and fuel consumption while increasing the air-to-boil temperature.

In combination with BLEX® technology available only at WingFan, we have extensive in-depth knowledge and many years of experience with the world's leading manufacturers to solve complex and challenging issues of the most diverse cooling systems in tractors.

Wheel Loader

Small wheel loaders usually require a very compact pulley driven cooling fan that is capable of overcoming high airflow resistance in cramped engine bays. New legislation to reduce the noise means that these fans are increasingly fitted with viscous clutches to control the fan speed in proportion to the cooling requirement. WingFan can deliver the clutch together with a special space-saving offset hub to ensure that the fan and clutch will fit into the most compact cooling packages. Low noise hydraulic driven fans for large wheel loaders are imperative for operator comfort and to comply with the ever increasing noise emission restrictions being applied to urban building sites. WingFan has in-depth experience in configuring a fan that will meet the most challenging operating parameters.
