Description for EWC Controls 12X8ND

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.

Features:

  • Heavy Duty Frame
  • Nylon Bushings for Quieter Operation
  • Revolutionary Motor with greater Reliability
  • LED's to Show Damper Operation
  • Low Leakage
  • Simple 3-wire Hook-up

  • ***Motor is always mounted on second dimension specified

          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.

                Replaced 3 older dampers with these EWC dampers. Much sturdier than previous units. Indicator lights are a nice feature. Easy hookup and new Trane system immediately recognized dampers after booting up system. Flawless operation to date.

                                        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.

                                        The new motor works with old motor's connections. This was a direct swap from a model 8 years old. Very satisfied.

                                            No. This a power-to-open and power-to-close damper. It is why it has
                                            three terminals: one wire for opening, another wire for closing, and the
                                            third wire is common. All terminals are marked clearly to identify which
                                            wire where. The damper uses electricity only for opening and closing. I
                                            have similar dampers in my hose. I like them, so far so good. The motor
                                            has mechanical and electrical (LED) indicators of its position. Keep in
                                            mind that the damper motor is not watertight and must be kept away from
                                            condensation (no water dripping on/in the motor).
