I’m building a spray room today in my shop and need to exhaust the fumes but the explosion poof fans are very expensive. The cheapest one I could find is about $600 dollars. So this is what I planed and I’m looking for your impute, ideas and thoughts. My shop is in my basement so it is mostly underground. The size is 30 feet X 60 feet. I’m going to build a wall across the shop 30 foot and 15 feet off the wall leaving a room 15×30. Then cutting that in half leaving 2 rooms 15×15 with a divider wall. Each of those rooms have a window in them at the top of the wall ( basement window style). The height of these rooms are 9 feet 8 inches taller then average. In the divider wall I plan on cutting 2 holes towards the top of the wall the size of a basic window box fan and installing a filter in them. The fans will blow air INTO the paint room through the filter and across the room and exit out the open window on the other side of the room with a filter in that window. With the window up high and the fans also up high I hope the create a cross ventilation high enough not to be blowing directly on the project but enough to exhaust the fumes and some over spray. What do you think?
