The hood equipment system of the bath patented by J-E TECH was applied to capture the pollutants generated in the zinc plating process. The main features of this product is to separate the treatment bath and outside air by installing an air-blocking baffle and then prevent the pollutants from exhausting into air by creating a negative pressure inside the baffle with a burial-type hood duct.
