Rectangular Damper | 10X10 ND MOTORIZED DAMPER

The ND series of Ultra-Zone dampers was designed with the installer and homeowners in mind. This damper is easy to install and easy to checkout. The LED display allows the installer to visually check the damper operation. With a sturdier frame, the damper installs in the duct much faster and easier and the nylon bushings ensure quieter operation. This is a feature that homeowners will never hear about! Quieter operation and a longer life motor equals NO call backs. The motor for the ND damper is driven by 18″ lbs. of torque, possesses a manual gear release, 3 wire power open/power closed operation and fail-safe LED’s for quick diagnostic checks. The motor is UL listed and NEMA Class 2 certified. The easy access, quick connecting terminal block eliminates the need for wire nuts and allows for trouble free use. The ND damper has a 97% leak proof rating. Overlapping blades and a strong positive shut-off motor ensures accurate control of all zones. The ND dampers combined with an Ultra-Zone zoning system provides the most comfortable and reliable system in the industry. The ND is available in 8″ x 6″ thru 30″ x 30″ in even inch increments. The motor will be mounted on the second dimension when ordered. For example, a 16″ x 8″ damper will have the motor mounted on the 8″ dimension, while an 8″ x 16″ will have the motor mounted on the 16″ dimension. This will alleviate the confusion between side mount and bottom mount dampers. For added flexibility, ND dampers can also be provided with a spring return style motor. (Model ND-RSD). The ND-RSD is driven by 3″ lbs. of torque without LEDs. Note: Specify “spring closed” or “spring open” when ordering
