●Saves labor in water level management.
●A constant water level keeps the booth performance good.
●Can be attached to various types of coating booth.
●No auxiliary water tank is needed, resulting in space savings.
●The water supply valve is opened or shut as the upper or lower water level limit is detected.

Air-Type Automatic Water Supply System
     When a small amount of air is pushed out as air bubbles from the detection pipe inserted into the water, a push-out pressure is needed that changes in proportion to the water level (insertion depth). The system detects this pressure (back pressure) with a high sensitivity sensor and operates an air pressure valve for water supply according to the water level so as to keep the water level inside the coating booth within a certain range.
