The Vermeer VX 50-500 vacuum excavator from McLaughlin Group has a Tier 4 Final engine and an engine enclosure to help reduce engine noise levels and vibration. The unit’s 3-stage cyclonic filtration system allows for wet and dry vacuum excavation while prolonging filter life and keeping maintenance costs low. An improved external hydraulic door opens at an 85-degree angle, allowing for easy and rapid dumping and cleaning of the spoils tank. A mechanical cam-over locking system provides a 360-degree positive door seal, even under reverse pressure, without additional clamping requirements. The lockable control console has a color graphic monitor. Its low-profile design allows access to areas limited by height restrictions. 800/435-9340; www.mclaughlinunderground.com.
