The LP high-cfm unit from Vac-Tron Equipment uses a specialized in-tank filter inside the vacuum excavation unit’s debris tank that in most cases eliminates the need to add water to the microtrenching process. This filter eliminates excessive material from reaching the cyclone separator. The filter reduces cleanup time during the trench run because there’s no need to stop and clean out the cyclone or unclog the exit hose from the debris tank due to caked material. Advantages of microtrenching include a minimal cutting width that boosts installation production; reduced costs of backfill; shallow depth placement, which avoids encounters with existing utilities; and job site cleanliness. 352/728-2222; www.vactron.com
