Steps to ordering Rectangular 2 wire Dampers:
1. Size: Choose any size above. Standard sizes shown are custom-made in 3-4 business days. All dampers are slightly undersized 1/8 inch in both dimensions to slip into an existing duct. Add foam weather stripping to outside of housing to take up any extra space and get a tight fit. A slightly undersized damper works great, but too large can be a problem.
2. Choose Motor Configuration: “Power Open / Spring Close” OR "Power Close / Spring Open": Specify what you want this spring return damper to do when power is removed, either open or close. Tip: If you are hooking this damper to a simple thermostat or switch for direct control, order “Power Open / Spring Close”. If used in a zone control system, order “Power Close / Spring Open”.
3. Which side do you want the motor mounted on? Standard and most common is a side (short side of the damper) mounted motor, but you can also have the motor placed on the long side, or bottom, of damper, at no extra charge.
4. Choose motor voltage: Our standard dampers are 24 volts AC, which is the standard voltage in the HVAC industry, however 110 volts AC is also available for an additional charge.
5. If you need special sizes or options, don’t hesitate to call. When in doubt, just call us at 972-633-8104 and we will answer any questions you have!
