When paired with the Geberit in-wall toilet system, the company’s Sigma80 flush actuator keeps things hands-free. Touchless operation helps prevent the spread of disease, while dual-flush operation provides water-saving efficiency, Geberit notes. The front surface of the Sigma80 is available in black or mirrored glass. Low-energy LED light bars in five user-selectable colors show the user where to wave a hand for full flush or half flush. The Sigma80 is compatible with Sigma concealed-toilet tanks for 2-by-4 and 2-by-6 construction. Ideal for residential or semi-public spaces, the glass plate can be locked for tamper resistance, and the unit can be set for automatic flush.
