The 5 Gallon DosaCart is a portable system for diluting chemical concentrates on-demand and applying the solution as a fan pattern spray on to any surface. This system uses a water-driven, non-electrical chemical injector (available separately) to draw chemical concentrate from an on-board pail and blend it into the water stream to create an accurately diluted solution. This complete system is mounted on an all stainless steel cart and includes a water filter, water pressure regulator, pressure gauge and flow restrictor. Available fully adjustable proportioners cover dilution ratios from 1:3000 up to 1:5 and a choice of Viton, Aflas or Kalrez seals are available for chemical compatibility.
