HVAC Motorized Zone Control Small Rectangular Damper

This damper is sold nationwide under major HVAC manufacturer's name and is our most popular rectangular damper. Damper is available in any of the sizes listed below for this price. Used for zone control systems or slave zones into unoccupied areas, these dampers are all 24vac driven and can be connected directly to a thermostat for simple control of any room or office. Constructed of all aluminum and stainless steel parts for long corrosion free operation, these dampers are tested to the industry standard 250,000 cycles of operation, and carry a one year guarantee.

Do not be concerned by the low price, these are top quality dampers that are being sold factory direct by our Ebay store “Dampers Direct”, and the only thing they are missing are the several levels of price markup that is usually present on this type of damper.

Our ebay store, “Dampers Direct” is run by RetroZone Inc., which specializes in HVAC zone control systems and dampers.

Existing duct systems, these dampers work great! If you need multiple dampers, check out our retrofit Flexdampers(tm) at “Dampers Direct”. Zoning control and air control become feasible even when you need 10 or 20 dampers in a duct system.

Steps to ordering These Rectangular Dampers:

1. Size: Choose any size below; odd sizes can be accommodated but add a $10.00 charge and expect at least a two week delivery. Sizes shown usually ship in 48 hours. All dampers are slightly undersized 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.

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 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. You can get this damper with a bottom (long side) mounted motor for an additional $10.00 charge.

An example part number might look like 3150 10 x 08M PO, meaning an 10 x 8 damper with the motor on the 8 inch side, in a power open, spring close configuration. We will communicate with you prior to fulfilling your order to ensure you get what you want/need.

Due to the large number of sizes and configurations available, these dampers are not returnable and are non-refundable. Ask questions and measure your duct carefully and ensure you order the correct size. Each damper is made to your specifications.
