Horizontal flow in powder booths has long been a well-known and widely used solution.
There are thousands of cabins with filters in the side wall opposite the gun or many guns in automatic nests.
ADAL has been building KPC cabins for years, in which ventilation is carried out through a vertical gap in the rear wall of the cab.
This solution worked in practice for manual cabins.
In recent years, we have built such cabins for automatic processes, either with one slot for rotary parts, or with two for flat parts with two sets of guns.
