The phase of drying takes by choking the amount of air, which enters into the booth.
This is done by means of n.2 shutters inside the heat generator.
The air, which goes through the booth during the phase of painting, is not recycled and
therefore pushed outside which allow for the evacuation of the solvents given off during the drying, rechange with fresh air is higher of 20%.
Due to the open circuit, the recycling of air between the booth and generator is avoided.
