The air unit (1) has a blower (37) for blowing surplus particulate material off the products (42). A suction material (38) draws off air, with particulate material from the air drawn off, from a coating machine (2). A separator (12,28) removes particulate material from the air drawn off. A pump (10,30,31) feeds a portion of the air drawn off to the blower. An independent claim is also included for an operating method for air unit. |
