So does this unit pull outside air into the crawlspace or does it exhaust air from inside the crawlspace to the outside?

We are using ours to exhaust air from inside the crawl space to the outside. I don't believe it is intended to work the other way around.

This unit exhausts air out of your crawl space, which in turn draws air from outside in through your other vents.

None and it pulls cold air from the room thru the front vents with the squirrel fan.

I've been using mine in a 2400 sf crawlspace in NC and been keeping the humidity at 62 pc. So far so good!My unit has the built-pump with the hose running outside thru the foundation wall.

It exhausts through piping (i used dryer type), through attic to vent on side of home. You don't ever want to vent into the attic. That can cause all kinds of problems. It's very quiet and looks great. Not a lot of fan power so best for a smaller bathroom. We are very happy with it.

This fan pulls air through it. I have it installed in an outside wall of a bath. Thus air (an moisture) is pulled out of the bath and is exhausted outside the house.If it were installed in the wall between the bath and bed rooms as you suggest, moist air would be exhausted into the bedroom - not a good idea because it could promote growth of mold.

This didn't apply to me. I built a small hobby paint spray booth and mounted the exhaust fan directly to the wall for direct venting into a crawl space above some eave vents. Input is open with some baffles in front to have consistent airflow across the paint booth.

It would move air, but what is your intent? If you use it as an exhaust fan you would have to move air from someplace else in the room (open window). If used as an intact fan, then it would make a positive pressure environment if no outside vent/window/door is open.

The unit usually comes with only one tube for the exhaust to the outside. The problem is that the air that is expelled outside must be replaced inside the room which causes the air conditioner to suck air into the room even though it is closed up through any opening it can find such as under the door or through other openings around windows or walls at the mopboard. I always purchase a second tube for the intake air from outside to replace the exhaust air so that the room can maintain a seal and allow the air conditioner to operate more efficiently instead of drawing unwanted warm air into the room to make up for the exhaust air lost to the outside. When you read the owners information, you can see how to purchase the additional tube and fittings or you can go on-line to get it. I also fabricated my own window insert made out of thick plexiglass for the window connection so that it doesn't look like the window has changed in appearance. I line up the two tubes with the exhaust tube on top as hot air rises and the cooler intake air tube on the bottom. Works perfectly! You will have this problem with any portable air conditioner you buy, but you are lucky that this is one of the few brands that has made provision for you to connect the second intake air tube as most do not.

they both blow air. It will work better if you cover the other vents with another pair of shoes. Also, during the winter I would keep it inside the house instead of the garage.

It sucks air in from the sides and blows it out the top. I keep mine about a foot from the wall.

no it does not. its a ok unit the fins that open up during operation are a little flimsy but it will move alot of air!! i have a 30X40 shop with 10' ceilings all i do is crack a window or a door and the fumes/ dust is gone in no time.

No, it doesn't. It pulls in thru the front & exhausts thru the back. You have to give it space to 'breathe' off of the wall... Still works well though in small bedroom.

Yes it does. Mine is against an outside wall, and we were able to switch the ventilation function so instead of recirculating the air, it is actually thrown outside the house. It increased my countertop space tremendously. Hope this answer helps you. (we bought this one because it has the best rating on Consumer reports).

Yes it does. It was a nightmare trying to get it vented outside. It just blows hot air everywhere. I returned it it was just terrible. Having hot flashes in California during the hot spell of the century I ordered this thinking it would be a life saver however my ceiling fan did a better job.

It has two fans. One for removing or exhausting air from the restroom and out of the house through ducting. The second fan is connected to the heater and blows the hot air into the restroom. Each fan is controlled by a separate switch.

1st answer is incorrect. Air conditioners recirculate inside air over a cooling coil - they do not "pull air from the outside," unless you use the vent function (which this model does NOT have).

Air blows out of the front . It pulls the air from the vent and into the room . It can not be reversed unless you are mounting it from the inside . If you are trying to push air through the system . So it does exhaust into the room .
