How well does the damper seal outside air from coming into the room?

The damper seal does not and cannot completely seal cool air from migrating back inside. Having said that, the cool air in my case is in my garage with all doors closed particularly in the winter and the air also must make a right angle turn to move back into the house. Under my circumstances I find very little coolness coming from my garage. Hope this helps and sorry for the delay.

I have never had a problem with cold air leaking in. I do live in Florida now and I really don't have cold weather compared to Illinois where I am from. I even had one of these fans in my home in Illinois and still did not have any problems.

I had no problems at all with it. my only problem was with the extra long plastic knobs which you would need if you put on new tiles. The knob in the box was too short.

things get damp, yes. it isn't dry, but it does cool the area down at least 10 degrees or more

I also live in the NE (MA). Although the louvers close by themselves, they are not a good seal against warm air (air that you just paid to heat) escaping. If you have the fan at a high spot in the house, the pressure will be for the air to force its way out throught this loosely sealed, and un-insulated opening. It is unlikely that cold air will come down, but you will lose significant heat through this opening. The cold air will be drawn in elsewhere in your house to replace the air that you are losing here. So, with that said, here is what I did: I built a plywood box lined with foam insulation. The open bottom rim is lined with weatherstripping. It is sized to be bigger (L X W) and a bit taller than the fan assembly. It simply sits over the fan assembly in the attic during the heating season. Also, I made a "cap" of plywood, thin insulation, and weatherstripping that is held against the louvers on the living side of the fan assembly by straps that go around the fan support struts (they pass through, and partially hold open the louvers). Thus, the fan is sealed from both sides, and this prevents any warm air escape through the whole house fan. The bottom line here is that the real issue is to eliminate, as much as possible, any air that you have just paid to heat from passing through this loosely sealed opening in the most heat-loss-vulnerable part of your house. I don't know how this help forum works, but if there is a way, I can send you pics of what I have done if what I have given you is not clear.

I used this fan to move dampness out from under house after a water pipe leak. It is best not to use in early morning and at night time when the humidity is high. It has some automated controls, but I do not trust them and just turn mine off and on when I feel it the best time. You have to have a second open, unblocked vent to draw in drier air and an open vent to mount in over on in for it to work best. As others have said, there is no damper and wind could blow back from the outside if the fan was turned off. For me that is no problem. Good luck.

I use my fan in my garage. I am located in Southeast Georgia, and relative humidity is always very high. I have not had any problems with its operation or with it rusting. I am glad I bought this fan, and I think you will be happy with the performance and the esthetics. I would recommend it for under a porch awning.

If you don't aim the AOS away from the counter top it will dampen or leave water. I haven't noticed any dampness on the floor.

Hi, It will keep everything locked up, but it will not prevent moisture. Air will come in from the sides.

It is good. It lets some moisture through, but I had mine out in the snow and no problems, just some damp spots

We don't get a LOT of wind at our house. However, on the times that it has been breezy, this fabric doesn't let a lot through. If I had to guess, I's say that it only lets about 1/3 of the air-flow through. However, that's normally quite enough to keep the air fresh and allowing hot air to be pushed out. We've never found it stuffy.

no, not necessary. but you need to put some sealant on the damper if you want it silent.

It just needs to make a seal, with most of the air out. You don't need to hear a click

11102 wouldn't be particularly effective for room "sound proofing" as it's designed as a sound damping. I really rather doubt that much vibration or rattle is coming through a residential door. However, the thickest closed cell foam would moderate some transfer.

This fan is a bit on the loud side so I wouldn't plan on locating it too close to living spaces. But the fan is solid, runs great, and moves A LOT of air so the trade-off is probably worth it if you're looking to reduce heat in a closed space. I purchased some rubber dampeners (small rubberized washers) and placed them between the four metal mounting brackets of the fan and the plywood to which it mounts. This might have helped some but the fan is still quite loud. So I'm not sure the extra effort and cost of the dampeners was worth it. All in all, it's still a good fan for the price.

I would have to assume yes it would keep them out. When the damper is shut there is a positive pressure from the spring, which keeps large gusts of wind out, and stays shut when placed in a horizontal or vertical position.

Yes. The back draft damper allows airflow in only one direction. Moving air forces the damper open. When air flow stops, the damper closes. Note: install the damper vertically. I believe this damper is gravity closed.

I don't talk a lot with mine on, but I haven't had any trouble with moisture getting trapped inside.

DampRid does absorb moisture from the air significantly. I assume this DampRid Super System is too large to fit in a safe. It is suggested for use in a medium sized room. Maybe buy a smaller DampRid product. They do work very well. The super system lasted three months in my room which is about 20ft L x 16ft W x 12ft H.
