The Quadrasan dosing unit from Vectair is a highly precise, automated urinal cleaning system designed to tackle bacteria and odors. The system is programmable and adjustable based on the amount of foot traffic at different times of the day. You can choose between unfragranced and fragranced 310ml cartridges for cleaner fixtures with a pleasant aroma. The Quadrasan system can also work in tandem with the Vectair Sensaflush Water Management System to further prevent bacteria and scale growth.
