Key features of our PMAX5

Lower noise emissions

Lower power consumption

High airflow and static pressure

Low projected width

Suitable for Puller and pusher applications

Modular fan for engine cooling

Low overall axial width and high blade
stiffness to minimise deflection.


The PMAX range is the latest generation of axial impellers designed specifically for high pressure demands and challenging inlet conditions in engine cooling applications.


PMAX5 has significant efficiency gains with lower noise emissions over a wide operating range. The modular design makes it a very versatile impeller for a broad range of engine and other high resistance cooling applications.


With 60 years of experience in aerodynamics, using a flexible and modular fan system paired with efficient motors and drives allows Multi-Wing to offer modular fan solutions showing improved cooling performances within the same power envelope.

Energy saving

Multi-Wing offers energy savings without compromising on cooling needs, improving lifetime and energy balance of products, systems and applications.

PMAX5 is optimal
for the following applications

Large excavators


Large wheel loaders
