Seko ProMax 4-Product Wall-Mount Venturi Chemical Dilution System – One-Hand Slide, Flex Gap, 1 GPM

The Seko ProMax 4-product venturi system dispenses up to four chemicals from one unit with convenient one-hand slide activation — press a bottle or bucket against the lever and fill, no free hand needed. A dial selects the product and a Flex-Gap membrane protects the potable water supply, while the hydrodynamic venturi holds accurate dilution at low pressure. Modular and tool-free to install, it suits rooms running several cleaners.
