High-capacity series of vacuum excavators has tank capacities from 1,600 to 3,000 gallons, sizes that allow crews to do more on drilling job sites, the company says. The machine can pothole and also remove drilling fluids from bore projects and then dump the spoil once at the end of the day. A pressure feature pressurizes the tank and quickly forces fluid out through the 6-inch gate valve. According to McLaughlin, a 2,600-gallon spoil tank can be offloaded in 8 minutes. And optional 1,200-cfm deep blower option, at 23 inches of mercury, speeds up the process. The standard blower is 1,025-cfm at 15 inches of mercury. The unit has a 99-horsepower Kubota engine. Total weight of a filled 2,600-gallon tank plus 300-gallon water tank is approximately 68,000 pounds, the company says, which requires a 2- or 3-axle truck chassis for mounting.
