Never ‘batch mix’ your cleaning agents ever again. The patent pending Pro-Portioner system allows you to draw from individual tanks of your pure products and proportion them to your individual desired mix. Need a 4% mix on the roof and 1% on the house that’s no problem simply set your mix ratio and when you need to change it turn the valve. Never again will your mix be too strong or too weak, the Pro-Portioner will allow you to adjust your mix on the fly. The Pro Portioner works on the inlet side of your pump system and is compatible with 12volt pumps, air diaphragm pumps, booster pumps and other demand pump systems.
