Smithco Safe Fill SystemSmithco “Safe-Fill System”
The Smithco Safe Fill System is a self-contained eduction system that allows the operator to mix liquid and dry chemicals safely and quickly.

  • 316 Stainless steel venturi provides highest eduction rate and durability against all chemicals.
  • Safety – All crop protection chemistry is mixed at ground level. Cleanload eliminates the need for operators to climb on and around machines while handling expensive and dangerous chemicals. Operator exposure to slips, trips, and falls is reduced. Chemical spill potential is reduced, minimizing operator and environmental exposure.
  • Optional suction lance allows the operator to educt bulk liquid and dry chemicals (wettable powders, dry flowables and water-dispersible granules) from large containers without secondary handling.
  • Robust tank and bottle rinse nozzles designed to wash Cleanload hopper and triple rinse chemical containers of residue.
