REVOLUTIONARY MODULAR CHEMICAL APPLICATION

The Milwaukee 3019-21PS M18™ SWITCHTANK™ system is a game-changer for facility maintenance and landscaping professionals, engineered to eliminate the physical strain of manual pumping while solving the logistical nightmare of cross-chemical contamination. By utilizing a modular architecture, this system allows users to swap dedicated tank assemblies for different chemicals in seconds, ensuring that herbicides, pesticides, and fertilizers never mix. Driven by the M18 REDLITHIUM platform, it delivers consistent, high-pressure performance that traditional pump sprayers simply cannot match, providing a massive boost to fleet productivity and site safety.

  • / SWITCHTANK INTERCHANGEABLE DESIGN / Isolate chemicals by swapping tank assemblies, eliminating the risk of residue contamination and increasing asset utilization.
  • / INSTANT CONSTANT PRESSURE / Achieve up to 120 PSI with no manual pumping required, drastically reducing operator fatigue and ensuring uniform coverage.
  • / 5-MODE ADJUSTABLE DIAL / Fine-tune the flow rate and pressure between 20 and 120 PSI to suit everything from delicate botanical misting to high-reach vertical applications.
  • / 20FT VERTICAL SPRAY DISTANCE / Power through demanding exterior applications with enough pressure to reach second-story eaves and high foliage.
  • / CRITICAL COMPONENT PROTECTION / Integrated Viton seals at key points provide enhanced chemical resistance and long-term durability in harsh environments.

Fit great

Been a couple of months and they seem to be holding up nicely. Real picky about fit of socks and these fit well. They are very thin but very comfortable.
