A centrifugal fan is a type of fan that uses centrifugal force to move air. Air enters through the center of the fan at the impeller hub. The air then exits the fan perpendicular to its point of entry.
The pressure generated by centrifugal fans is higher than that of axial fans. Centrifugal fans allow air to be transported through ducts even when there is some resistance (pressure loss). They are effective at overcoming obstacles in ductwork.
Backward-curved centrifugal fans have more streamlined blade shapes, specially designed for improved efficiency.
Backward-curved centrifugal fans provide high efficiency and can be used without a scroll casing (housing).
They can also be mounted on a module: a galvanized steel or plastic frame including an air inlet. The complete assembly is delivered ready to be installed. Simply place it in your application and fasten it.
ECOFIT backward-curved centrifugal fans are equipped with plastic or galvanized sheet metal impellers, with impeller diameters ranging from 133 to 315 mm.
They are fitted with single-phase AC external rotor capacitor motors, 230V 50/60Hz or 115V 50/60Hz, or with EC motors (electronically controlled to adjust the airflow rate in real time according to ventilation demand).
The ECOFIT fan models presented on this page are standard references. Based on your specifications, we can develop a custom ventilation solution to meet your specific requirements.
