Seko ProSink 1-Product Wall-Mount Venturi Warewash Dispenser – Flex Gap, 4 GPM

The Seko ProSink 1-product venturi dispenser accurately doses and dilutes detergent or sanitizer into a sink at the turn of a knob — no power or air line needed. Its compact Flex-Gap backflow preventer protects your potable water supply while keeping a smaller footprint than an air-gap unit. Durable stainless steel construction and a quick-connect manifold make it low-maintenance for foodservice, hospitality, and janitorial warewash.
