An inlet guide vane assembly for controlling air flow through a fan. A plurality of shafts are mounted extending radially inward of an inlet cone, and are affixed to a hub positioned at the center of the cone and concentric thereto. Rotatably mounted on each shaft is an adjustable inlet vane, having a crank arm extending from its root end. Cam follower bearings are used to rotatably mount a ring on the hub. The ring is connected to each of the crank arms by a link having a ball and socket joint at each end. Rotation of the ring thereby causes the inlet vanes to rotate about their supporting shafts without binding.

Fan inlet guide vane assembly

A centrifugal blower for air conditioning applications is shown having an adjustable inlet guide vane control for a blower wheel having forwardly curved blades. The pivot axis of each inlet guide vane is substantially offset or displaced from the plane of the inlet guide vane.
