This has less than 1300 hours on it. We bought it used in Spring 2013 and have all of the records since that time. It has gotten regular PM.
Spoils tank: 10 barrel ~ 550 gallons PLUS the vertical tanks in the back that can capture the cuttings when potholing.
Blower: This is the stock blower for the Vacmaster 4000 – 1000 CFM, Tuthil brand, model 4612-46L2
Fresh water: 85 gal fresh water tank. The Vacmaster heavily marketed that they were the best at air-vac vs. water vac and this machine can do either one. Air vac produces less risk to utilities than water jetting to excavate w/ a vac. Vacmaster has a proprietary nozzle for performing the air excavation.
