Customer Questions & Answers

is the transformer and motor included in the order like shown?

Asked by: Fred

is there a directional flow?or can it be installed as both an intake or exhaust vent to be used at different times?

Asked by: greg
I used mine so the air flow exited the crimped end just like you would normally install all round duct work. That way it won't leak air as much. But, I don't see how it would matter if you can mechanically get it to work in your situation.

Can you connect the transformer to a manual 120v wall switch to open and close the damper manually?

Can you connect the transformer to a manual 120v wall switch to open and close the damper manually?
Asked by: captcanuk
I would say yes. I happened to measured the 24V current at around 400mA before I installed mine. I would expect the current on the 120V side to only be around 100mA including any transformer losses. So, any wall switch will easily handle the load. But, you will have to be handy enough so you can safety wire the transformer in a way that will not be an electrical hazard. load would only be about

I purchased 2 dampers to use with my intake and exhaust ducts in my home air exchanger. One of the units was not assembled well or it adjusted in shipping. The gasket that holds the damper in the closed position was misaligned and I had to adjust the gasket so it was aligned correctly to hold the damper completely shut in the normally closed position. I reinforced the gasket adhesive on both units with a caulk bead in case the gasket adhesive failed with aging. Note that the motors get rather warm so you will likely not want to wrap the damper completely in insulation or I suspect they may get too hot. If the motors last and do not burn out prematurely, I will be very pleased with these dampers.

Rated 2 out of 5 by from Short-lived motor life. Not a Home Depot off-the-shelf item. On-line purchase. Worked like a charm, but motor jammed after 2 weeks. Called Suncourt, got a return authorization, and expect a new motor, based on the attention from the phone rep.

Rated 5 out of 5 by from 6" fresh air damper. Excellent expected ! We have the 3 usual gas items in our laundry room, the Central Air, Dryer, and Water Heater. I dont understand why houses aren't with a Damper.

Rated 4 out of 5 by from Works great, some small tweeks needed The damper works great. Installed it when adding a new bathroom fan because we get strong canyon winds which would drive me crazy rattling the old vent flap. Now it is nice and quiet! My attic above the bathroom is accessible so installation was straightforward. Tied it into the line that activates the fan and it opens in a couple of seconds when the fan is turned on. I did adjust the foam insulation that seals the damper when closed. Out of the box there where gaps between the foam and damper which would have let air and noise through. Pulled up then reinstalled and reglued the foam and it was good to go.

Rated 4 out of 5 by from Beware of binding As a note, I have only installed three units so far, one to go. None have been functionally tested in the final system yet. The automated damper seems sturdy and well built. The metal gauge of the body is fairly thick so that it holds its shape well. Tolerances inside are generous so that the flapper has plenty of space and won't bind on the inner surfaces of the body. But... some designer didn't do the tolerances correctly on the bolt which acts as a stop for the flapper. A little bit of distortion in the right direction on the body and the flapper assembly gets push up so that the cast feature which is used to turn the flapper, and the bolt that controls max open and closed positions interferes and the flapper sticks open and won't move. Careful attention is needed to ensure that assembly does not distort the outer housing causing it to bind and prevent the mechanism from working. To give yourself some extra breathing room, remove the threaded bolt and grind two flats in the threads where is passes nearest the cast component. The two flats should be about 1/2 inch long on opposite sides of the threaded end of the bolt, beginning at the threaded end of the bolt. Re-install the bolt with the flats aligned to increase clearance to the cast component and the bar that the motor operates to engage the cast component. A picture should accompany this review to show the places for the flats to be ground. Even if you install it perfectly with no distortion, I'd still grind the flats so that if the system sags or creeps a little over time the cast component does not bind up and negate the reason you installed it.

Rated 5 out of 5 by from Perfect product for the price I bought it to use it with my humidifier & it does exactly what it's suppose to. Now the bypass in my humidifier is only open when needed(humidistat calls for more humidity) & it's also eliminates the need of manually opening & closing the damper when season starts/ends. Price is more than reasonable

Rated 4 out of 5 by from Update to: Beware of binding Now have 4 dampers up and running for several months. They shut off flow to a basement when the blower is turned off so that the basement and the 2nd floor stay the same temperature, no filtering of heat from the basement to the 2nd floor, or cold air down. Something to watch out for: Each time the dampers open and the small spring is stretched, it makes a little noise. From the first floor it sounds like someone is plucking a violin in the basement. Just enough to make your wife nervous if she is at home alone. This caught us off guard several times and I had to demonstrate it for her so she would relax about the funny noises. When the dampers close, there is also the soft sound of gears being spun as the spring returns the damper to the closed position and the motor's gearbox spins backward. Not loud, but just enough to put the unsuspecting person on edge. Makes for good jokes about the house being haunted.
