The ECO200 is a truck-mounted vacuum excavator that features a 215-hp (160-kW) Volvo diesel engine, a three-stage cyclonic filtration system and spoil tank capacity of 1,600 gal (6,056.7 L) with the standard option of 600 gal (2,270 L) of fresh water. It has a 6-in (15.2-cm) hose diameter and a 3,500-cfm (29.1-m³/min) "free air" blower capable of 18 in Hg (.6 bar). The tank, power pack and water system all have a modular design -- versatility that allows a contractor to mount the unit on either new or used truck chassis.
