The majority of water evaporates while people dry their hands with an XLERATOR/XLERATOReco/ThinAir hand dryer; however, some water droplets can get on the wall and floor. The ADA-compliant recess kit (40502) for XLERATOR/XLERATOReco hand dryers will help to keep water off the wall and floor. The black (89B), white (89W) and brushed stainless steel (89S) wall guards fit securely below an XLERATOR/XLERATOReco/ThinAir hand dryer to protect walls. If water on the floor beneath a high-speed, energy-efficient hand dryer ever becomes an issue for any of our customers, we encourage them to put an anti-microbial floor mat below the hand dryer.
