Simpson SKS Hi-Capacity Supermarker GT

Part #FM600

Hi-capacity foam marker produces high quality foam in mix chambers mounted on the boom. Foam is produced instantly after turning on the unit or when switching from side to side. This produces a thick and heavy foam similar to shaving cream allowing the foam to stick to the first thing it touches. This consistency of foam also makes it much harder to be broken down by the sun, heat, wind and humidity.

  • Pump, compressor and solenoids are mounted neatly on a slide out base on the bottom side of the tank. Easily accessible by loosening winged bolts on the tank front.
  • 6 - 3/8" threaded inserts are securely molded into the bottom of the tank so the unit can be mounted to a steel mounting plate or stands on your sprayer.
  • Aluminum and stainless steel hardware along with poly fittings are corrosion resistant.
  • Solenoids are equipped with epdm seals and stainless steel components.
  • System Includes - 22 gallon tank with compressor and valves; in cab control box with wiring harness; sufficient hose for an 90 ft. boom; (2) foam-mix chambers; (2) collector heads; hose clamps and mounting hardware.
