Abstract
For the application of humidity-sensitive, aqueous-based paint by spray gun, a compact air shroud assembly adapted to be attached to the spray apparatus about the air cap of the gun to envelope the spray with hot, dry air. The air shroud includes inner and outer annular members to define a passage therebetween. Hot, dry air enters the annular space from the bottom in a direction generally normal to the paint spray pattern and is divided into separate flow paths by a baffle below the inner annular member. From the baffle, the separated air flows pass to various segments of the annular space as directed by vanes in the annular passage. The vanes redirect the flow into a direction parallel with the spray pattern.
