• The "WF" fans are noted for lower initial cost, proven reliability and quiet, efficient operation for applications involving low static pressure.

• The "WF" Series fans utilize a cross-frame assembly to support American Coolair's unique bearing and shaft assembly.

• This stationary shaft mounts on the cross-frame member and the power is applied directly to the cast aluminum hub.

• Drive belt power is applied to the fan/hub assembly in the same plane as the bearings.

• This reduces bearing load and dramatically increases fan life.

• Bearings are permanently lubricated and sealed.

• The six die-formed steel propeller blades are securely attached to the hub to form a strong, rigid propeller assembly.

• The fans can be sized to handle air demands in the range of 2,000cfm to 31,000 cfm.

• The motor pulley can be opened to reduce fan speed and thus decrease air flow on all models.
