I have single story home with 1870 sq ft, 30 watt fan can handle cooling my attic?? or do I need two fan's??

Hi - you need to measure the sq feet of your attic. This will determine the solar attic fan you should purchase.Each solar attic fan has the sq ft its rated for. Thanks Dave

I think if you another one will cool your house more and take the humidity out of the house. Any way they are free energy,

Hello there, 2 fans might work well - in my installation, I only installed one fan near the bottom blowing the air upwards. That seems to keep the fan motor out of extra heat from the frig. and should extend the motor life... I am in SW Texas and it does get hot here... Good Luck with your project!!

My apartment is 600 sq. ft. and I have the AC in the living room. It has somewhat of a cooling affect on the kitchen and dining area, but very little affect (if any) on the bedroom which is around the corner and down a little hall from the LR. I have a ceiling fan in there, and did manage to get thru last summer (my first in this apt.) without installing another AC in the BR. But it was my ceiling fan that made that possible.

im using a 4 inch inline fan i bought at htg for 1 600w hps in a 4x4x7 and it isn't cutting it ( temps in the 80's) so with 2x 600w you might need something better than this

Sorry I have no idea. When I had my roof replaced, I had the roofer install it and my son is the one suggested I get a attic fan.

Probably couldn't hurt if you have the room, I thought about doing the same. The fan is decent for what it is, but doesn't push all that much air. You could wire both fans to operate on the same switch. I have noticed that the fan does help the performance of the unit in hot temps. Good luck dude.

This is a very powerful fan ... much more so then a standard attic ventilator fan. If you put it in a window pulling/blowing air out with another window open to let air in for cross flow, I'm sure it would cool a attic very quickly. Remember it will only get as cool as the outside that it is pulling in. If it's 85 outside than it can make your attic any cooler than that.

Yes. As well as I use ceiling fans. I have an old home with a lot of walls and it cools the entire downstairs.

I have the dual fans (4000 cfm) ... using to cool a 355 SBC they are quality units, work fine, however, they draw a lot of juice and are noise.I had to go to a 140 amp. alternator to carry the load. I'm going to put seperateswitches so I can run 1 fan on cool days and 2 only when needed to drop the loadand noise. engine mounted in a '74 260Z roadster conversion with tight engine bayso cooling, even with an alum. rad. and ceramic coated headers a task. Fans did the trick.

yes, just about right, get ready to deal with circulating the heat out. Negative fan pressure will probably be the way to go, for that area it may take 2 or 3 6" or 8" tube type fans blowin out from the top & pullin cooler air in from the bottom.

I'm sorry I don't know. Both my homes are one story and the fan works great in both homes. Good luck.

Not really. Does not impact my house in that way. If anything the fan just helps air circulation in the attic.

I use mine EVERY day here in Florida, BUT... I use it pointed in the area that I am working. It is a small fan that is great for personal use, but I really don't think it would be efficient for removing the air volume of an attic.

Two fans might work depending on the size of the shelter. I use for my tent that sleeps 10 and inside my house in the kitchen also.

30w is your limitation. 4 fans at 7w each would be fine. 4 fans at 8w ea would overload the circuit. Check the fans you wish to use and see how many watts they would each pull when at full power. You can get this information off the fan manufacturors website.

I replaced a fan/light of different type without needing my attic access. Check the dimensions of the Broan and the dimensions of your old fan. Also compare the size of your existing exhaust pipe with the Broan.
