The RAMVAC HX-12/27 conventionally sized hydroexcavator from Sewer Equipment has a 12-yard debris tank for when the operator can’t leave a job to unload material. It comes with a temperature-controlled environmental chamber and directional discharge system to off-load debris back into the excavation site when finished without dumping the tank. It has a long-range wireless remote, NEMA 4 electrical system, a 400,000 Btu water boiler, a three-stage filtration system and a 5,400 cfm blower with 27 inches Hg. It is available with a RamAir air excavation system to avoid adding water to problem areas. 800/323-1604; www.ram-vac.com
