I`ll attempt to show you guys some pics of my pit. I`m new at this. I designed and built this dry clean work pit. 12'x3'x6'deep.12" of 2" drain rock all around walls and under floor to keep all water away. Has a floor 4" drain too. Can never fill with water. Has Lots of lighting/air line for air tools. Wall pockets for tools /beer. Hard wired phone and most important outside forced fresh air to prevent carbon monoxide/ or dangerous fumes from poisoning me. They can sink into a pit! I`ll post more pics later.

I think you would want to push the air out of the pit not into it. Any air brought into the pit would go up leaving the CO2 in the pit. Me thinks atleast.
