The VX30-300 vacuum excavator weighs 9,999 pounds with a 300-gallon spoil tank. A 31-horsepower Yanmar diesel powers the unit. A hydraulic door enables quick dumping and cleaning of the spoils tank. It has a patented cam-over locking system that provides a 360-degree positive seal, even under reverse pressure, without additional clamping requirements. The unit’s 3-stage cyclonic filtration system allows for wet and dry vacuum excavation while prolonging filter life and keeping maintenance costs low. The VX30-300 also comes with a tandem axle chassis, which aids in stability and axle life.
