GDS, GDR & GDF Forward Curved Centrifugal Fans

GDS, GDR & GDF Forward Curved Centrifugal Fans

Versatile OEM Focused Compact Centrifugal Fans 

GDS, GDR & GDF forward curved fans offer a highly efficient, low noise solution for low pressure applications, particularly in compact spaces. Higher volumes of airflow can be achieved due to the wider scroll housing and dual air inlet, drawing in a higher volume of air up through its wider exhaust outlet. Send us your enquiry or give us a call to discuss your application in more detail. We’ll select the correct fan model that will meet all your requirements.

External rotor motor fans for OEM's

Offer Convenient Speed Control and a Constant Reliable Airflow in Confined Spaces

The Ecofit range of external rotor motor fans are designed to help original equipment manufacturers save space within their products and, if necessary, to obtain speed control by means of low cost triac electronic or auto-transformer voltage variation. They provide an ideal solution for fan coil units, air curtains and general HVAC.
