There is a 24inch drum fan against the back wall blowing right at the miners. The 6inch duct brings in cold air from the AC. The orange blower is attached to a 4in dryer hose that pumps some of the heat outside and some into the finished side of the basement where the air return is.
it aint pretty but it works.
