3150 Series Rectangular Mechanical Dampers

OEM quality damper is sold nationwide under a major HVAC manufacturer's name and is our most popular rectangular damper. 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. Also works with any zone control

system using a 2 position, 24vac damper. 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. All damper blades ride in nylon bushings, for rattle free operation, unlike some other brands, and are made in the USA using

the industry proven Hansen “Synchron” motor, with a current industry leading low replacement cost of just $55-compare that to other brands!

that is usually present on this type of damper.

Existing duct systems, these dampers work great! Any of our Robert

If you need multiple dampers per zone, 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.

Fast Track Service: most dampers, including "option 1" on odd sizes, ship

within 48 hours.

Steps to ordering: Rectangular 2 wire Dampers:

1. Size: Choose any size above; Standard sizes shown ship in 48 hours.

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 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 of $11.

5. How to order: Just buy a damper(s) in the above size range you need,

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!

Due to the large number of sizes and configurations available, these

dampers are returnable only subject to a 25% restocking fee. Ask

questions and measure your duct carefully and ensure you order the

correct size. Each damper is made to your specifications
