I have a 2600 sq. ft. single level home. Would it be better to install 2 30 watt attic fans?

If you live in a hot weather area....I'd say two. So far my one solar fan seems to work fine but the attic still gets hot on hot days. I ignore it....it's quiet. If you live in a windy area simple roof vents may work as well. Good luck.

I think in very well might be better to install 2 of them. I have a single level 2400--but has a bonus room above garage--and a very tall attic space. I got 1 and it is only cooling my attic 10 degrees or so in the heat of the afternoon. I may look to buy a 2nd one later on down the road.

Yes, I would recommend 2. We have a neighbor who has a house similar in size and two are adequate for this square footage

If your attic space is tall or you live in an area that has very hot days, I'd say yes. I installed two gable fans and one 30W attic fan in the middle. This is for a 3000sq ft house in NorCal. Hope this helps.

The more ventilation the better. As long as you have pleanty of soffit vents three would work well particularly if you live in a climate that has high heat and humidity

Judgement call; more always better but hard to justify the cost. I think I'd do just one and make sure the attic is well vented otherwise to move air easily. And adjust the angle appropriately for summer at your latitude (about 10 degrees off of flat horizontal - that is, tilt it just a little bit due south).

All depends what your running in it. Also the avg temp of the air in your space. I haven't installed any extra fans aside from the H100 I use to cool my cpu. So for a basic build you should be fine.

Frankly if the cabinet is open, you do not really need the fan. Biut given the choices, I would pull air through the front and exhaust to the back.

I would go bigger because you're room has almost 400 cubic feet. You want to turn ask the air in the room over at least once probably more per minute. Also the fan you are looking at is not strong enough for that filter let alone the one you really need. In that size of a room I would go much larger because I assume you are trying to cool lights with this set up as well and I don't think that this combo would be cable of pulling enough air over your bulb to keep anything bigger than a 400 w cool enough to not cause problems in the grow area. Speaking fun experience you need your fan to be rated significantly higher cfm than the filter to sustain enough airflow to keep the light cool as well. Be patient and purchase the right materials off the bat or you will end up purchasing new equipment that should have been bought the first time. Just my 2 cents. A lot of money can be wasted because you cheaped out up front. Save the money you need for high quality equipment and you will get much better results. That being said this filter is great for the amount of cubic feet that it is designed for. Just go with the 400 cfm range one and you will be happy aslong as your fan is not cheap and can pull through the filter as well as cool your light. Peace.

I'm not really sure. I was told If volts are same you can use it. Doing pretty good on my attic fan. Wish I would of went bigger. 4 bedroom house to much square foot.

you can use one fan if you like. You wont get the most out of the cooling, but it will still cool very well. My recommendation would be to replace the fans with one really good SP120 fan. Here is my install video of the process. https://www.youtube.com/watch?v=rrBfVgpGhUc&list=PLvd6GtnBmcZlnf43RFLr16nLSY8dWYXqQ

I think It would be far to much for that small space. IMHO!!! But One would probably be okay with a couple good exhaust fans. good Luck!!

You should install fan within two feet of the roof ridge. You can rotate it in any direction you want and then adjust the angle of the panel up and down also.

It would be best to set on floor then set fan on top and force air towards attic. But you can suspend it from ceiling by screwing hook into roof and bungy cord it there to cut down on sound/vibration. I use mine from the floor threw lights into attic.

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

Cannot say for certain but my whole house fan its installed for is quite substanial compared to your planned use

Our home is 1400 square feet and it's just right. I think the larger unit would be too much. This one could probably go up to 1500. We have 4 of the 1/2 round roof vents and 2 of the ~12x16 dormer vents - that's more than enough to vent the air out the roof. You'll also notice secondary cooling because the attic get's aired-out. The noise isn't bad - of course that's subjective. Anyway, we have no central air and when it cools off outside at night, the fan cools the whole house very quickly. During moderate days, it keeps a freshing breeze throughout.

That sounds good, consider where your make up air is going to come from. Without a good free flow source of make up air, you will notget much flow. Perhaps you have a shady and low and cool side of the house where you can add a vent for make up air. The opening for the make up air should be approximately the same square inches as the fan.

I think the fan is way too small to remove sufficient air from a normal size attic of a home. For the attic you need and attic fan, as they are much larger and made to remove lots more air.

The key will likely be do you have enough ventilation...It does not include a thermostat, so something with one might be a better idea.It does have a much stronger motor than most permanently mounted fans that I've seen...

I would definitely look for quieter fan. Scale of 1-10 . 10 being loudest. This fan would be a 7. You can insulate it and make it quieter. There is some really quiet fans out there. Most people use these in attics or in an insulated box. Google it and there is alot of info out there.

I'm using my fans in a similar situation and they work great. My set up is off grid so these fans are perfect for venting kitchens and bathrooms.
