Not much, but it doesn't take a lot when the walls of the box are made from 12 mm ply only. The loading on each wall is equal to the surface area times the air pressure. It doesn't take much pressure to cause a problem, since the panel bay is big enough to accommodate a 9'6" concert grand panel. >Do you have the production needs to dry a board that fast? Not really, but the fan is only 125W output. See specs below; I haven't actually checked the pressure head in the delivery duct to get an idea of the current flow volume, but it certainly seems to be flowing adequately. It takes about three hours to reduce the moisture content of spruce down to 6% from 9% with a heat input of around 1000W. Although I would be inclined to leave the panel under static conditions for a couple of extra hours, just in case the moisture gauge is reacting faster than the panel.
