Exhausting

[ToyMeKaNeK]

Hi, new on board, would like to install an exhaust fan in the wall to keep the garage ventilated.
Just to let you know up front I've made up my mind on what I want to do, but If someone has better ideas, by all means, speak up.

I have a good size space. 23X24' with tall ceilings. 11'4". I have no windows so in colder weather with the double door closed, it gets mighty smokey and dusty in there.
I would like to install a thru-wall exaust fan. I picked a 10" 470cfm fan. Because of space to put it, I had to rewire the wall and run a new source to location. Wasn't easy since it's sheet rocked.
I also put in a variable fan switch rated at 3A in series along this wall.

I'm About to make some cutouts in the wall. I need a 10-1/4" circular cut interior and exterior, with a 14-1/2" square of exterior siding cut out first.
What's the best way to make sure both holes are aligned properly?

There definitely no electrical, plumbing, or insulation to get in the way. Just a clean shot between the studs.
Thanks for reading, and let me have your thoughts if you think the ventilation won't be enough.

are you going to install a filter so you dont get dirt and junk blowing in?
keep in mind that the filter will reduce airflow

I think thr best deal is to use the whole house fans and blow up into the atic and route out from there

I thought of that, but man, that's a lot of fan, don't ya think? And look at the the take up air needed. Great if the door is wide open, but most of the time it will just need cracking for the smaller fan idea.
Above my attached garage is a bonus room with a crawl space on each side, so your idea is doable, but I'll think small for now.
Thanks for the responce, bob.

Drill a hole or pound a large spike through from one side to the other and use that as your center. Check for wires and pipes first.

Can you mount the fan close to where the smoke will be generated? This will help conserve the treated air and allow most of the dirty air to be removed. What about adding a hood?

The fan location will be in the little nook where the water heater and compressor are. Yes, that's where most of the smoke and dust are so that should work out.
Hood? I bought this fan online. It has an outside hood if that's what you mean.
It has a pull chain to open/close the outside, and also an internal switch that way.
Here's a link to it.

I think it is a little small. It will help, but will take a while to change the air.

there are products meant for garage ventilations, I would stay away from the bath and kitchen fans..

Please make sure adequate make-up air is supplied when running any exhaust fan. The potential for back drafting can occur with these type exhaust fans. That means devices such as gas water heaters and gas furnaces in the same rooms as these exhaust fans, where there is no source of make-up air will pull air from the path of least resistance. This could include, your water heater vent pipe, furnace vent pipe, etc. The potential exists that gas from these appliances could also be pulled into the area you are exhausting.
