Controllable Pitch Fans

Controllable Pitch Vane Axial

Sensors compensate for changes in temperature, humidity, air flow, gas concentration or air quality by altering the blade pitch to increase or decrease air volume or pressure. Fan is ideal for VAV systems and for industrial applications requiring a constant environment regardless of air demand.

Controllable Pitch Vane Axial Fan Applications

Chicago's Design 47 Vane Axial Controllable Pitch Fans respond automatically to signal source based on changes in temperature, humidity, air flow, gas concentration and air quality. While low initial cost, simple installation and operation make the Design 47 the best choice for variable air volume systems, they are also used in industrial applications to maintain constant environmental conditions regardless of air demand.
