M Series

Series M adjustable pitch fans are available in diameters up to 20 ft (6.1 m) in eleven different blade profiles. Both clockwise and counterclockwise configurations are available, in both standard and reverse mounting types.
The blades (either aluminium extruded or FRP pultruded) are connected to the hub through a high quality steel shaft.
The patented M hub consists of two precision machined steel forgings, clamped together to sandwich the blade shaft. One of the two pieces incorporates the hub boss.
The M hub is available in five different sizes, depending on the fan diameter and number of blades. The connection to the driving shaft can be provided either through a cylindrical bore or a tapered bushing.
