Ventless' spray booth uses 90% less air than more traditional booths according to the company. Ideal for smaller applications, the booth features four stages of filtration designed to capture all dust particulates and remove all VOCs from the air. This allows for clean air to return to the booth in a downdraft format. The company says it conserves energy by eliminating the need for 100 percent makeup air, preserving indoor heat in winter and cool air in summer. It features gas phase filtration, a VOC scrubber, and an air curtain that blocks dust from entering the booth while in operation.
