The FX50 is with you every step of the job.
Key Features
  • With the FX50’s optional reverse flow and standard full-opening, hydraulic tank door, offloading spoils is quick and easy.
  • 49-hp Deutz diesel engine provides ample power for all machine functions.
  • FX50 is equipped with an extremely efficient Tuthill® 1020-cfm blower and a powerful water system with a water-pressure capacity of 3000 psi and 5-gpm flow.
  • The FX50’s wide range of applications includes exposing buried utility lines, storm drain cleanout, directional drilling site cleanup, water leak repair, valve box and utility vault cleanout, commercial/residential debris cleanup and landscaping, and posthole digging.
  • The FX50 is the quietest vac in its horsepower class, for minimal disturbance in noise-sensitive areas and greater operator comfort.
  • Fully enclosed, insulated and lockable power pack leads the industry in noise reduction while protecting major components from weather and vandalism.
  • A choice of spoils tanks (up to 800 gallons) and water tanks (up to 500 gallons) to meet the requirements of virtually any size soft excavation or cleanup job.
  • Triple filtration system with a cyclone separator cleans the air before it ever reaches the filter, minimizing maintenance.
  • Autoclutching feature disengages the water pump when water is not in use, allowing full system power to the blower.

  • Water pressure can be adjusted from a curbside operator’s station that allows one-person control of all unit functions.
  • System may be ordered from the factory either trailer-mounted or stand-alone, so you can mount it on your own trailer or flatbed truck.
