Circulates, supply or replace the air. Air Supply Unit is useful where the air has low humidity and hot climate. Air Supply Unit (ASU) comprises a series of filters & eliminators. The unit uses the atmospheric air, refines the air, and gives it to the Paint booth via ducting, and creates a constant flow of dust-free air into the paint booth. In this case, maintenance is deficient as compared to the Dry type of air supply unit.
Wet type of air supply unit is useful in the high and continuous production system. In this unit, dust particles are arrested with water circulation filtration media and a highly efficient exhaust system.
