can this be used for a dryer

Asked by: lo
Yes, but I wouldn't use this type. Any lint that passes the dryer trap will plug the vent. Use one with flap doors instead.

can i use this for an additional returngrill & motorize with skelton duct motor?

Asked by: spike
Are you referring to a cold air return for a forced air heating system? If so, I would not recommend it. In order to work efficiently, forced air heating systems require a large amount of return air to replace the air it is heating and blowing up to the hot air registers. Even with a duct motor, these eave vents simply would not supply enough return air unless you installed a lot of them. My recommendation would be to stick to vents that are designed to be cold air return vents.

4 in. Eave Vent for Bath Exhaust is rated 3.6 out of 5 by 8.
Rated 5 out of 5 by from So far so good... Installed in a wide perforated vinyl soffit right outside the bathroom window. Louvers allow pointing the exhaust away from the house; very little flow resistance compared to anything with a damper (the bath fan already has a built-in damper; another one at the exhaust wouldn't do a lot). If duct resistance is also low, the moist air will be blown clear of the house, preventing re-uptake into surrounding soffit intake vents. NOTE: The stop flange is VERY narrow, and there's nothing on the plastic collar to lock the vent in place on the soffit- so 1) take care to avoid cutting the hole bigger than it needs to be, and 2) use a good caulk-like adhesive around the flange, then come up with something to hold it in place until it dries. I used aluminum duct tape around the perimeter; that seemed to hold pretty well. GOOD LUCK!

Rated 4 out of 5 by from Nice Vent - but not as pictured Vent comes without the steel extension, otherwise nice piece, good looking.

Rated 4 out of 5 by from Just what I was looking for. Used for exhuast for bathroom vent. Wish it had screen to keep out Bugs.

Rated 3 out of 5 by from Nice idea, fits in small places, but has a problem. All houses have dust, so what happens when moist air and dust get drawn through the fan and out the vent? Those thin vent louvers clog with dust. One day I realized the bathroom was getting fogged easily while taking showers. Got up on a ladder outside and those thin and dense louvers were clogged. Even with a high power shop-vac I had trouble cleaning it. I ended up using a long thin blade to pluck out all the dust as best as I can. Works better now. I think I will have to replace this with a spring loaded vent, but those are large and require about 16-18" sofit and 6" of clearance to install since they are meant to fit 4, 5 and 6" ducts. Have to figure out something. If this vent is all you have room for, great. If not, be prepared to get out on a ladder to clean it out every so often. One last thing is since there isn't a large flange, you need to drill a hole the perfect size. Zip ties don't work out to attach the duct because of that. I ended up using metal HVAC tape which worked perfect for a tight press fit.

Rated 4 out of 5 by from Simple and efficient!! A great vent for bathroom fan exhaust in a soffit!!

Rated 1 out of 5 by from Bad Design compared to others on the market I used a 4 and 1/8 inch holesaw in vinyl and the hole is too large. A bigger flange is needed so the vent can be screwed in place. Look around before buying this.

Rated 3 out of 5 by from A basic vent cover The description says it comes with a fan, which it doesn't. There is nothing that holds it on, so definitely don't' make the hole to big. If your going to paint it, Id' sand it with some fine sand paper, but the paint peels right off if you don't.

Rated 5 out of 5 by from Low resistance soffit vent "slats" far enough apart for low flow resistance but unlikely to clog. No damper (fan already has one and would impede flow). 4" hole saw worked great. Great product.
