Crossflow (Tangential) Fans, Fan Wheels and Fan Heaters

Airtek crossflow fans are used wherever air is required to heat, cool or ventilate. Crossflow fans, also called tangential impellers have a long cylindrical wheel with many small blades at the periphery similar to a fan wheel with forward curved blades. Contrary to centrifugal impellers and axial-flow fans, the main flow crosses the blades of a crossflow fan twice (see fig.1).

Some advantages of crossflow fans are their compact cross sectional size and the long fan lengths that are possible. Airflow is uniform over the length of a crossflow blower which makes it a good choice in applications where an even flow of air is required over a given length of heater coil, evaporator coil or ventilating equipment.
