Sloan Valve Co. offers two series of waterless urinals: the WES-4000 and WES-5000.

Sloan Valve Co.’s Water Conservation Division offers the WES-4000 and WES-5000  waterfree urinals, which feature narrow-profile styling and require a smaller footprint than the company’s other waterfree urinals. Models WES-4000 and WES-5000 are made of vitreous china and are wall-hung, wall-outlet units. All of Sloan’s waterfree urinals use a proprietary cartridge installed at the base of the urinal, which holds a sealant liquid.
