Description
–
A single blade round damper with a (2) two position, 24 volt motor. The motor is powered both ways - powered open and powered closed. The motor features LED's that indicate the position of the motor whether open or closed. The LED's are colored RED for closed and GREEN for open. These indictors are a failsafe measure meaning that they will not illuminate until the blade of the damper has gone to its full open or full closed position. The motor is a 3 wire hook-up with a common, a power open leg and a power closed leg.

Nice product
This damper appears to be sturdily constructed. The vane shaft rides in nylon bearings and it operates very smoothly. It has a nice flexible seal around the damper plate. The motor drive works very smoothly. I'm pleased with it. I installed it to be driven by a Honeywell TrueZONE HZ432K Panel Kit and it's working very well.

Supply House is Great, the product not so much
I had a prior model of this product and the motor died. Given the challenging access it would have been nice to just replace the motor but the manufacturer, EWC Controls, no longer makes/stocks the motor so I had to replace the whole unit. That was a major pain and an expensive one but I found Supply House had the unit for a significantly better price than the local EWC distributor. As I was able to block the old damper open I was able to wait a few days to save some money. I rated the product a three but I would give EWC one star for business practice and poor customer support but Supply House a 5 star rating for great service.

Packaging
I have mixed review comments. I have not used the dampers yet BUT I have used them on the other phase of the project and the work great and easy to install much better than the pneumatic type..
second comment is: the boxes they where delivered in where crushed and jammed into another larger box that was too small. I will carefully inspect when I install them.
This is starting to be a re occurring issue with supply house!!! This is the third order delivered that way.
Should look at your repackaging methods!!!

Good Quality Zone Dampers
We're re-doing a portion of a project that had zone dampers that were continually failing. The superior quality of these dampers is obvious.

Best round damper we ever use!
I have use different dampers over years doing zoning projects. This is far best round damper I eve come across. Seals great and there is no "wind" sound when that go to close position like dampers with seals glued to the body of the damper and not the blade. Great product !!!

Product Q&A
1 Question1 Question
Q: Can this product be used in the kitchen exhaust system-I have a 30" Broan Range hood, cabinet mount it is ventilated thru the attic/roof via 8" ductwork. I have a problem with significant backdraft-kitchen is significantly humid even when not using the stove. I installed a spring loaded backdraft preventer in the ductwork, right under the roof cap, it did not help.

If the damper is fully closed when the kitchen fan is off AND there are no air leaks in the fan exhaust ducting the damper will minimize backdraught when the fan is off.

Probably not. This damper is not designed to work with oil/grease vapor in the air (unless filter removes all fat and grease from the exhaust air). Oil and grease will destroy a rubber seal over time. Secondly, this damper requires power to open and close (three wire system). It means you have to figure out how to supply power when the hood is off. And one more thing, the damper works from 24 VAC, which most range hoods do not have. You may try Honeywell fresh air damper EARD8, but a few problems still exist - resistance to oil/grease and 24 VAC power supply. Plus, keep in mind that it will take 30 seconds for this damper to open (I am pretty sure there is a mistake in specification - damper is normally closed and needs power to open). Also you may check amazon.com - they may have dampers for 110VAC.

Try to experiment yourself. Close a exhaust for a day or two with rag, paper or towel and see if you solve a problem. If you did you can install a motorized damper. If not look for a problem someplace else.
