The V500 Light and V500 Light Heavy Duty are specifically designed as small, portable, light-weight units capable of potholeing and wet/dry remediation. Both utilize the three stage filtration process, have the power of full size units, and use a tandem axle trailer with a GVWR of less than 10,000 Lbs. In addition, both units are dual saddle tanks for fresh water that aid in trailer stability.
