Automotive Semi Downdraft

Semi Downdraft takes air from the upper level of the shop through a bank of filters in the ceiling of the paint booth and moves it to the back of the paint booth. It is then filtered through the exhaust system at the back of the booth and released back into the atmosphere.

The filtered exhaust air is pulled through the exhaust plenum and discharged straight up and into the atmosphere through an exhaust stack. (Optional Equipment)
