Abstract
A self-contained fan turret unit for use with a tower air recirculating system includes a housing positionable for attachment to the tower system. The housing includes an extendable column assembly bearing a turret assembly to which are attached one or more fans, inlet bells and discharge cones with the turret assembly being movable from a position within the housing to one above the housing by the column assembly. The turret is supported by an air spring isolator and, when extended, is connected to the housing and the tower unit by flex joint isolators. A cowling is also provided for releasable attachment to the turret. The turret is rotatable and extendable arms are provided to interconnect the column assembly and the fans for selective removal thereof from the turret.
