The Vacall AllTrench vacuum/hydro excavator’s features include a 35-gpm at 2,000-psi water pump with variable flow output controlled by the operator; a 12-cu-yd debris tank; a 1,500-gal aluminum water tank; and a 5,000-cfm/16-in. Hg blower. The machine is capable of a 26-ft boom reach with an extension and has a continuously adjustable boom speed. Front-mounted boom is standard, while a rear-mount boom is an option.
Standard equipment includes a rear decant and cyclone separator designed to filter out particles ranging from 10 to 100 microns. The cyclone spins the air, slowing it down and allowing a steel funnel in the lower section to channel any carryover material into a dropout box below. The cyclone also has convenient cleanout doors on both top and bottom. Plus, a removable steel microstrainer basket, in the final stage of the four-stage filtration system, provides absolute vacuum protection.
