Hi Guys,
I am putting a 14ft long, 3.5ft wide, 6ft deep concrete mechanics pit into my home shop. I have some heavy equipment and a lift for 40k+ lb machines isn't going to happen. And the pit is already in the process of being built, so merits of pits versus lifts aren't helpful at this point. This is something that will get used for 10's of hours per year.
Once of the frequently cited concerns about pits is ventilation. I don't want to go overboard, but I do want to take it into consideration. I am forming the walls today, so I have the opportunity to put in some penetrations without too much difficultly.
I am thinking that a 3" or 4" PVC pipe out from near the bottom of the pit at one end, horizontally under the slab, and then 10ft up a wall to a duct blower that is sucking air. Shop air would be drawn through the open top of the pit and anything hanging out at the bottom would be sucked out. As the building will eventually be heated, my plan is to exhaust the air back into the building so I can potentially do a fairly high flow fan and not waste a bunch of heated or cooled air.
Thoughts? Thanks!
