I am moving my shop into a basement in a commercial building, there are no windows in the room or HVAC, but I plan on having the contractor cut a space in the wall cinder block wall for a wall unit AC/Heater, there is not enough space outside to have a mini split unit, so a through wall unit will have to suffice.
The shop space is 400 square feet.
I am concerned about fresh air ventilation and generally being able to clear out the dust in the air. I have a ceiling mounted air cleaner from Jet and a cyclone dust collector, but I would like top get some sort of fan/air exchanger that can have mounted through the wall to the exterior of the building that can swap out the dusty shop air with fresh air, or at least something to pump out the shop air and open the shop door and rely on getting fresh air from the rest of the building.
I want this fan/air exchanger to be as small as possible to limit the size hole I need to cut in the wall.
Thanks so much
