QuattroSelect Chemical Dispensing System is a wall-mounted dispenser that accurately dispenses four products into bottles, buckets or floor care machines. Dispensing system features rugged steel doors with lockable cabinet doors (keys included) and product identification windows. Drip tray includes a drain hose and remote high-flow bucket/autoscrubber fill gun. System is built with one-handed, 1.5 gpm, low-flow, low-foam bottle fill. 8' long hose features a 3.1 gpm, high-flow fill rate with point-of-use activation. SmartValve technology automatically chooses the correct flow rate in one operation. SafeGap and Air Gap eductors meet the ASSE 1055B standard for back-flow prevention. Dispensing system uses super-concentrated and hyper-concentrated chemicals to cost-effectively reduce solid waste disposal. Spill-Tite cartridges are leakproof to virtually eliminate chemical exposure, tampering and manually diluting products.
