Abstract
An automotive paint booth containing multiple contiguous chambers can be supplied with down flowing air streams in the various chambers for removing airborne particulates produced by the painting operations. Cross flow of particulates between contiguous chambers can be controlled by slightly varying the down flow velocities in the respective chambers.
Claims4
An automotive body paint booth comprising multiple connected contiguous treatment chambers adapted to have automotive bodies pass sequentially there through in repetitive fashion;
- means for moving air downwardly through selected ones of said chambers for removing contaminants from said chambers;
- and means for controlling cross flow of air between said chambers;
- said cross flow control means comprising means for measuring the cross flow between adjacent chambers and means for measuring the down flow within individual chambers.
An automotive body paint booth comprising multiple connected contiguous treatment chambers adapted to have automotive bodies pass sequentially there through in repetitive fashion;
- means for moving air downwardly through selected ones of said chambers for removing contaminants from said chambers;
- and means for controlling cross flow of air between said chambers;
- said cross flow control means comprising a two axis ultrasonic anemometer having a first emitter-receiver combination oriented to measure cross flow between adjacent chambers, and a second emitter-receiver combination oriented to measure down flow within an individual chamber.
