Product Q&A
10 QuestionsQ: I have a motorized damper I use for make-up air for my Kitchen range hood. The damper is wired to open when I turn the hood fan on. Closed when the hood fan is off. Recently the damper opens and closes when the fan is in the off position. What would cause this?
Asked by R D 10 years ago

Verified Reply- Supplyhouse StaffThat appears to be the wrong damper for your application. that is a powered closed normally open damper.
Q: I have one that stays in the open position when no power. Is there anyway to reverse it to be in the closed position with no power.
Asked by Eddie 11 years ago

Verified Reply- SupplyHouse StaffYes, the damper can be field-converted to a power open/spring return closed damper when used as an independent zone or for fresh air intake for ventilation or combustion make-up air.

Q: 24volt AC or DC ? Spec doesn't say
Asked by Rick 11 years ago

AC – try the manufacture’s web site for more info. Wiring is strange to me. – Again look at the manufacture’s web site.
24 VAC
These are 24 volt ac units.
Q: Did this 7 inch Damper fan unit did come with power attachments cables, that cable go to between aDamper to boiler gas control modules?
Asked by Sani 11 years ago
Add your answer
Hi, The damper has two wire leads that you need to connect using wire ties to a 24VAC control circuit. Cheers, -Dave
The damper does not come with control wiring capable of returning to the control unit. Sent from my Samsung Galaxy Tab®|PRO
Q: What is the net free area when open? These appears to be a lip that the movable damper presses against when closed. What size is that lip? I.e. How much does it protrude into the duct? If 1/2 inch, then a 7 inch duct size is effectively 6 inches?
Asked by Steve 13 years ago
Add your answer
Yes, there is a lip/ring inside which has a foam tape seal. I can't get at it to measure it, but from eying it I'd say the inner free radius is about 3/8" less than the nominal radius. Cheers, -Dave
Yes it does about ½ inch, if it calls to use a 7 inch use a 7 inch, it’s not about square inches if there is any type of fan sucking or blowing through it. (Static Pressure), If you are getting this technical you need to call in a mechanical engineer. Nick Duval, President City Wide Sheet Metal, Inc
The gasket material is roughly .500" thick so yes, the open area will be the duct size minus the gasket thickness. However, since the air flow rate from the blower is relatively low the gasket size will not hinder performance. Michael Nix
Q: Does automatic dampers come square? 20/1-2x8
Asked by Blazenhot 14 years ago

Verified Reply- PexSupply StaffAccording to the manufacturer, the ZD dampers are the square or rectangular versions of the ARD damper, and the ZD dampers come in many sizes. ZD dampers should only be used with zone panels. They should not be used as fresh air dampers or for independent zone control.
Q: Does the motor remain tuning when in the power closed position after the damper has been closed or does it continue to run to keep it closed.
Asked by james 14 years ago

Verified Reply- PexSupply StaffWhen an ARD has been driven to the closed position, the blade hits the gasket and the resistance against the motor is high enough to cause the gears to lock up. When controlled by a Honeywell zone panel, the dampers are all open when in idle mode (no call for heat, cool, or fan from any zone). The dampers are also open when that zone is calling for heat or cooling. The only time a damper gets powered closed is when one zone is calling for heat or cool and another zone is not calling. At that time, the zone that is not calling will get powered closed and remains powered for as long as the panel wants that damper closed. As soon as power is removed from the damper it will spring open.
It was a long time ago, but as far as I remember the motor stops after the dumper has been closed.
Motor remains powered and 'stalls'. When power is released spring opens damper (turning motor backwards). You can reverse setup as well to make it a powered-open (instead of a powered-closed).
This damper is power to open. It closes via spring force once power is cut. So power on is open, power off is closed. Sent from my iBananaPhone
I don't think this is a motor; I think it is a solenoid. If youre refering to your zone controller and the fan motor; set your damper to be normally open. This way if your fan is still slowing down the dampers will open and won't cause an increased pressure in the manifold or collector box. Hope this helps.
Q: I have what I believe to be a 16 inch round honeywell damper in my AC system. The unit is set up for power close and spring open. The retrun sping is broken. Can I replace the control unit on top of the damper without changing out the entire damper?

Verified Reply- PexSupply StaffYes, it is part M847D1012 ( http://www.pexsupply.com/Honeywell-M847D1012-Replacement-Motor-for-ARD-EARD-ZD-Dampers-11625000-p ).
Q: I have a swamp cooler hooked up to the same duct work as the Central HVAC system. I would like to damper off the swamp while using the heater or ac and not have the heat or cool air to go out through the swamp cooler. So I thought I would put in a damper, I want to control the open and close in the house and not have to climb up in the attic to do this. Will this do the trick? Do I just put a switch on it and open and close when I want to use the swamp?

Q: is there anyway to reduce the noise the spring return makes ?
Asked by MG 16 years ago

Verified Reply- PexSupply StaffWhile there is no concrete solution to this problem, we recommend applying a small amount of lube to try and reduce the noise the spring return is making.
I sometimes hear it, but scarcely it bothered me.
