ABSTRACT:
A wet pump-less spray painting booth is provided that more efficiently removes overspray paint particles from the air and uses substantially less make-up water than prior designs of wet pump-less booths. In a rear air cleaning section of the booth, blower-generated air flow sucks water from a lower reservoir up through ducts into an upper plenum where the air and water impact against a splash plate, creating a turbulent mix of air and water. Water from the upper plenum drains through tubes to an upper reservoir and overflows the upper reservoir along a sheet, the bottom edge of which is spaced a substantial distance from the lower reservoir, creating a water curtain. Air flow is through a user portal where the air becomes laden with overspray paint particles, through the water curtain below the sheet at a relatively low velocity to partially clean the air of paint particles, upward through the ducts, into the turbulent mix of air and water where the air is further cleaned and upward through the plenum to an exhaust.
