As a vacuum truck, the MX-660 is hard to beat: It has a long deck with a 500-gallon vacuum tank, a 48V-10HP @ 2400 RPM electric vacuum pump motor with 20 in.Hg continuous / 27 in.Hg intermittent vacuum performance, top-and-rear clean-out doors and much more. With our option packages, it quickly becomes a potable water tank or high-pressure washing tank carrier. In fact, with its unlimited configurations, this zero-emission vehicle can adapt to virtually any application.
