Manual balancing dampers concealed above a sheet-rock or gypsum board ceiling or in other inaccessible locations present control problems. Access doors are rarely acceptable to the architect or owner.
Young Regulator has developed the Bowden Cable Controls to remotely adjust these inaccessible balancing dampers from a distance as great as 50 feet by using a rack and pinion controller and a flexible casing and wire assembly.
The Young Regulator 830ACC is the rectangular, opposed blade damper designed to work with any of the many Bowden Cable Controls. The opposed blade design is preferred to a single blade damper because it distributes the air evenly over the face of the damper for less noise and turbulence.
The Young Regulator model 830ACC2 is a rectangular opposed blade damper that is controlled from inside the air stream with the Bowden Cable Controller Model 270-275 or 270-275-ML. This solution provides precise control of inaccessible balancing dampers without disturbing the integrity of the architectural ceiling. The rack and pinion controller is accessed with our model 030-12 control wrench through the opening in the slot diffuser.
The Bowden Casing and Wire’s outer spiral sheathing is secured to the damper frame and the inner wire is fastened to the slide. The push-pull motion of the Bowden Rack and Pinion Controller opens and closes the damper. BCW length is limited to 20′ when it runs inside the air stream.
