SWMN | I have one at the ceiling with a door on it and a 8 in pipe coming down to welding table. If wielding I take the cap off above my welding spot or if you want to take air out of the whole shop I pull a rope to open the door by the fan I have a diffrent rope to pull the door shut. It workers alright but if you are welding in the shop away from the duct it takes forever to clear the shop. It works better to open the big door for 1 minute . Our fan is a old 12 inch fan from a hog barn. | ||

Jesup, IA | Here is what not to do. When I built my 80' x 80' shop, I put in two 24" Farmtek livestock ventilation fans on a timer. I have no idea what I was thinking, as I had to carpenter in an inlet later. You can't run those exhaust fans without a way for the air to get in! The inlet (36" square) has motorized louvers. On a snowy day it sucked precip right into the building until I got an exhaust hood on the outside of the building. Finally, the fans themselves have exhaust hoods, but not motorized louvers. On a breezy day they slap and bang. Be sure to get motorized ones so they do not do this. And think ahead where you want air to enter the building when you run the fan(s). Works good now, but if I was doing it over, I would have planned two smaller inlets. | ||

Chaffee, Western New York | None. But I picked up a big old "smoke eater" from a bar when they banned smoking in NY. It has the same electric filters as a welding filter system. If can keep up with 3/16 7024. Diesel exhaust is not an issue as nothing will fit inside my 16' deep shop. Door is only 7 x9. | ||

NW Iowa. / SW Arizona | Here is what I use, nothing fancy but also cheap. I'd love to have a air filter system in the shop especially when I'm welding but try to limit my heavy welding until days I can open the overhead doors. I never let tractors run very long in the shop, I don't want that exhaust smoke on my ceiling or walls. I do have a tractor hooked up to a generator that stays in the shop but that is hooked up to a exhaust hose all the time if running. I'm using a 18" variable speed Multi-fan that is mounted on an interior wall that goes to my cold storage. I didn't want outside winds blowing into my shop even though it does have louvers. I can variable speed the fan and have it set up to runs any where from 5 minutes up to 30 minutes or have it locked on always until I shut it off. I do have to open a window to get enough fresh air in, it sucks a lot of air. I'm using an old IH 560 on my generator and it will warm up the shop 4-5 degrees even with my fan on full speed and a window cracked open 6 inches in cold outside weather.

Van Wert, OHIO | We just put ours up yesterday. It's a 24" whole house exhaust fan we got from menards. We put it in the middle of the shop in the ceiling and built a 2' box as to keep the insulation out of it. When on it pulls open the louvers and all exhaust is vented through the vents in the eves. | ||

North Central IN | +1. Built a door to go over the top so I didn't loose so much heat there. | ||

NW Iowa. / SW Arizona | That sounds like a better deal then mine. Mine won't pull the smoke up close to the ceiling like yours would. That is one thing I'm disappointed in with mine. Smoke is lighter then air and loves the ceiling :-). Got any pictures? | ||

NC Iowa | i have a 18" in the back wall mounted as high as possible. needed a louver and found one from farm tek. i mounted it in a box and then had foam sprayed around it. then i made an insulated door with a rope system so i could open it from down below. it is a variable speed type. i like the timer above, i will look into that as it would be nice to have it shut off without trying to remember.

Wi | Having an exhaust fan can be handy but its a backwards approach to many issues. Start with source collection. If you are welding, cutting, etc, setup either an exhaust arm for the area or buy a portable filtration unit to suck the majority of those fumes up. Those are the bad ones you don't want to be breathing. The source collection does not loose your shop heat either. If you have an area you know you will be running tractors put in an exhaust drop or a reel there. The next line of defense is commercial air cleaners. They slowly clean the air in the entire building, this takes out the exhaust from pulling something in and out or from a small accidental fire, etc everyday things that source collection is impractical for. With those two things the need for exhaust fans is gone and your shop will stay warm and your lungs will stay clean. It costs more money, but so does poor health down the road. If you were in a commercial setting those would be mandatory along with a certain amount of air exchange as well. | ||

NC IA | Air King I will sell you one for $1700 on your door or $1600 if you want to drive to NC IA. Keep the heat in and they work better that exhaust fan. 641 425 4163 (2012-04-13_08-55-16_365.jpg) Attachments ---------------- ![]() | ||
