Backward Inclined Centrifugal Impeller – for superior performance. This series of fans incorporates aerodynamically designed casings and streamlined inlet cones, which are compatible with both Laminar ( L) and Aerofoil ( AL) impellers.

High Efficiency / Low Operating Cost – characteristically these fans have a broad efficiency curve. This results in lower power consumption and operating cost for the life of the installation.

Quietness of Operation – the impeller design allows for air expansion over the entire blade width, with relatively low velocity and minimum turbulence.

True Non-Overloading Absorbed Power – the power curve peaks within the normal operating range and at maximum efficiency. Thus the motor selected for the desired duty is usually sufficient to operate the fan over its complete volume-pressure curve, without overloading.

Stable pressure curve – the inherent design of the backward inclined impeller results in a steep-rising pressure characteristic over a wide range of capacities. This ensures minimum changes in volume with shifts in system pressure, providing extremely smooth operation.

Series 1000 fans centrifugal fans are available with impeller diameters ranging from 310mm to 2260mm.
