The McLaughlin MEGA Vac 6-inch truck-mounted vacuum excavator gives utility contractors productive potholing. The flexible, modular design enables contractors to customize the 6-inch vac to suit their job site needs. It has spoil tank capacities ranging from 1,200 to 3,000 gallons and a standard option of 800 gallons of freshwater. It has a 6-inch hose width with a 3,200 cfm blower at 18 inches Hg. It is powered by a 200 hp John Deere Tier 3 engine. Its three-stage cyclonic filtration system allows for wet and dry vacuum excavation, and the cam-over hydraulic rear door provides a 360-degree positive seal to keep fluids securely in the debris tank. 800/435-9661; www.mclaughlinunderground.com.
