Duct Fans

Fully configurable to customer specifications


KPM duct fans are manufactured in house and can be configured to the customer’s exact requirements balancing power, pressure, diameter and flow. All units can be supplied with VFD units for full control.


All fans are designed with excess power availability so that blade pitches can be increased if a higher air requirement is required, especially if engines are upgraded.


The units are easy to specify and easy to fit and are the preferred choice of Shipyards due to their versatility and range of options.


Stainless and aluminium housings are available.
