What is a mixed-flow duct fan?


A semi-radial fan combines the advantages of an axial fan (moves large volumes of air) and a centrifugal fan (creates higher pressure). The result is efficient airflow with low energy consumption and reduced noise, ideal for continuous operation in demanding environments.


Quiet strength and durable design


The galvanised steel housing is lined with 30 mm acoustic insulation, which significantly reduces noise while providing thermal protection.

Inside, a three-speed single-phase asynchronous motor with thermal overload protection and sealed ball bearings ensures long service life and quiet operation.

Speed can be adjusted via the built-in switch (V version) or an external controller. The Boost-I fans can be installed inline between round ducts or suspended, and multiple units may be connected in parallel or in series to increase performance.

The result is a robust, energy-efficient fan system that delivers high airflow, low noise, and long-term reliability in professional applications.
