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. 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. ND dampers combined with an Ultra-Zone zoning system provides the most comfortable and reliable system in the industry.
