Crossflow/Tangential

Our crossflow fans (also known as tangential fan impellers and open frame blowers) are used wherever air is required to heat, cool or ventilate. They are either single or double units with long cylindrical wheels which are in turn constructed from many small forward curved blades. The main airflow crosses the blades twice which are contrary to how an axial-flow fan works.

Typically two-pole asynchronous motors with short circuit turns suitable for continuous duty are used. The most popular units are 230V although 12V-24V DC are sometimes available upon request. The construction methods of the housing enables the motor to be mounted in four positions, respectively 0°, 90°, 180°, 270°.

Additional Crossflow Blower Options

In addition to the 45mm and 60mm diameter wheel sizes which we keep in stock Pole Star also manufacture a number of other size wheels. Often there are minimum order batch quantities and manufacture lead times to take into account. The other sizes are:
