Vac-Tron Equipment’s HTV 573 PTO (Power Take Off) Truck, patent pending, is available on Ford or Freightliner chassis. The full HTV (Hydro Truck Vac) series has debris tanks from 300 to 1,500 gallons. The truck’s PTO drives positive displacement vacuum blowers producing 1,000 to 3,000 CFM. These units are standard with a high-pressure water system, full hydraulic rear door, reverse pressure and the “Big Red” filter housing, which cleans air down to 0.5 microns before passing back through the vacuum pump.
