When powder is blown into the oven.	Check the workshop for air currents.
Powder residue in the oven.	This can be prevented by regular cleaning.
Poorly cleaned recovery system.	Clean regularly.
When dirty air is sucked into the booth or the oven.	Under certain conditions the coating plant must be separated from the production areas.
