Q:Could this be used outside, in below-freezing temperatures? It would be protected from weather, under a porch, for wood stove air intake.

A:Â Hello, we do not recommend our dampers for this application. Unfortunately the low temperature would ultimately affect the function of the damper. Thank you.

Q:I have 3 of these. 2 of them often buzz for a few seconds when they are energized and start to open. They eventually stop buzzing and open as they should. How can the be resolved? Does orientation matter?

Answer This Question
A:Â Hello, this is not unheard of, but unfortunately this is also not normal and could possibly indicate a failing motor. However, it may continue to run for some time. We recommend monitoring the two dampers and if the "buzzing" continues become louder or for an extended amount of time before opening please contact Suncourt directly to begin a warranty claim as long as the units are within the warranty period. Thank you.

Answer This Question
A:Â Hello, yes our dampers can have power applied to them for an extended amount of time. The motor is designed to be able to do this. Please note that the motor will become fairly warm to the touch in this situation, but this is normal. Thank you.

Solid construction. The external pluggable transformer is a nice touch. Worked great for me. The only design gripe I have is the spring they're using. It's way too long for the task and looks untidy.

I was looking for a motorized damper to install in my Broan kitchen range hood, as cold air was pushing through the exhaust and into the house when the range hood was not in use. This is an excellent damper as it seals 100% when the flap is in a closed position and resting on the integrated neoprene seals. The motor is also extremely quiet, and there is no loud noise when the flap returns to its normal position (as with other dampers that are spring loaded)
High quality and good set-up documentation provided with the equipment

Using in the bypass duct to my whole house humidifier to stop airflow when theres no humidity call. The damper and humidifier are both powered with the transformer that came with this wired in parallel and so far it works great. The motor does get quite warm so make sure it has plenty of air space and not in a position where someone will bump into it.
