Motors and impellers

Together with the impellers, our motors are the heart of the fan. Our motors are produced in-house in our factories in the Netherlands. This does not only enable us to maintain high-quality standards, but also to increase flexibility.

The ultimate motor-impeller combination

By combining different impellers and motors, we have created a broad range of axial fans for a variety of applications. Depending on the application, we are able to develop a fan that performs better at high pressure, is extra efficient, and can move a lot of air over a long distance.

The ultimate motor-impeller combination not only ensures better performance, but also a minimal motor load, which improves the service life. To be able to guarantee you the best quality, all combinations are tested extensively during our rigorous test programs.

The impeller is a vital part of every fan. In order to guarantee the best performance, we have in-house development and production. Their design consists of several modules, which means we are able to give the impeller a certain character based on blade angle, blade profile and the number of blades. Depending on the type of impeller, it is produced from polypropylene (possibly reinforced with fiberglass or nylon) or aluminum. These virtually endless combinations ensure that the impeller always fits seamlessly with your fan.
