The SYSTEM 5000 from VACMASTERS has the ability to trench and pothole. All the components, including the 300 cfm, 220 psi compressor; the 1,400 cfm positive displacement blower; and the high-pressure water system; are powered by a single, enclosed John Deere 173 hp turbo diesel engine for quiet, dependable operation. It has a self-purging filtration system, selectable air or water digging, remote operation up to 200 feet away, fast-acting interceptor canister, fully supervised control panel, full-opening rear door, enclosed power-head and low-maintenance design. Its ability to use air rather than water when trenching and potholing means the job gets done in just four to five minutes in most soils, more efficiently (spoils stay dry for backfilling), more economically (mud hauling and disposal costs are eliminated) and more safely (air won’t damage utilities and is nonconductive). Air-vacuum excavation is DOT friendly and won’t damage the road base. 303/467-3801;
