POWDER PAINT BOOTH BACKFLOW FILTER APPARATUS

摘要

A novel filtering apparatus particularly adapted for a transportable, modular powder spray painting booth with backflow cleaning capability by having two sets of filters each associated with a separate output chamber such that in normal use, a vacuum draws air from the paint booth through both filters and in backflow use, the same vacuum draws air through one filter in a normal filtering manner but with the air first drawn through the other filter in a backflow manner.
