This is used for drying stains, fillers and other finishes.
A very rapid flash-off solvent (also water) is achieved by a high velocity and high temperature of the air.

This type of dryer is used primarily for drying water stains, fillers and varnishes in throughfeed operation. The drying process involves high energy consumption and exposes the workpiece surface to considerable heating. Particular care should therefore, be taken when workpiece edges glued with hot melt adhesives.
