The new TA-ABS ThinAir is a great addition to the Excel Dryer family. With its new slim design, this high speed hand dryer satisfies ADA depth requirements as a surface mount unit. The ThinAir requires nothing more than a simple wall mount installation eliminating the older methods of recessing hand dryers into the wall to achieve ADA compliance. If ADA compliance is a requirement, the TA-ABS ThinAir is the perfect solution! ADA guidelines state that fixtures mounted above 27" must not protrude more than 4" from the wall.
