Forward curve blower wheels are used in centrifugal fans and air blowers where large volumes of air need to be supplied in ducted air supply applications. Indiana Fan can supply, manufacture or rebuild hard to find and various types of wheels ranging from squirrel cage, forward curve, backward curve, backward inclined, air foil and radial blade in class I, class II, mild steel, aluminum and stainless steel for various speeds, temperatures and corrosive environments.

"Universal Replacement" means that Lau may be used to replace any type of propeller - regardless of manufacturer - in virtually all applications. There are only three basic important shapes that are of interest in the propeller selection - round, wide pressure and narrow pressure blades.

The round shaped blades are for used for free air delivery and low pressure applications, and are quieter.

The wide pressure blade is used in most applications operating at substantial static pressures. It has excellent pressure characteristics and reasonable noise levels.

The narrow pressure blade is generally used in applications where high static pressure exists, such as multi-row coils or places where minimum axial depth is necessary.
