Abstract
A spray booth especially adapted for painting operations having a dry filter module with features for allowing changing of the filters quickly and in a contained environment, which reduces exposure to non-authorized and non-properly-protected personnel. A carousel-like filter module flips a wall to move dirty filters into a containment space while placing clean filters in position to continue the painting process. The process and device in accordance with this invention is safe, repeatable, predictable, and capable of changing a large number of filters in a short period of time, for example, during lunch break or other short break in the painting operation.
