The Halsey Taylor HAC Series drinking fountains are self-contained, wall-hung units that have self-closing water activation controls on the front of the unit, as well as the left and right side with raised letters for the visually impaired. These Halsey Taylor water fountains come standard with the Double Bubbler, which projects two separate streams that converge to form a fuller, more satisfying drink. The HAC series also come in a hands-free, contactless version. Also, be sure to check out other great items from Halsey Taylor.
