Voltage, or volts, is a measurement of the difference between two electric fields (in heating terms, the difference between the Earth's electrical field and the electricity running through your wires).
The ND series of Ultra-Zone dampers was designed with the installer and homeowner 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 insure quieter operation. This is a feature that homeowners will never hear about! Quieter operation and a longer life motor equals NO call backs.

This product is significantly more robust than the older original unit and is very easy to install with minimal modification to the duct (new damper is thicker requiring about 2 inches of material to be removed - quick job with snips). The position LED indicators are a great enhancement to the older units making system diagnosis much quicker. Existing wiring is used and unit comes with clear diagrams.

heavy duty frame
The newest design of EWC motorized zone dampers have an improved power pack, but the frame is so wide it restricks air flow.

Simple and Reliable
I replaced 17 year old dampers with this unit. It is simpler, easy to install (10 min) and the new status LEDs make it easy to troubleshoot the system. The new design improves airflow when open, and is both quieter and more airtight when closed.
Works as intended

Comments about 8" x 8" ND Motorized Damper:
Used it to replace the old style EWC dampers. It is a more sturdy product. It fits the duct work much better and the vanes close more completely. Air flow to an opened / closed zone is much more efficient.
