EquipmentWorld.com | November 2017 19 marketplace | continued Less noise, more fuel efficient VMAC released its G30 air compressor with a new Honda GX390 gas engine that offers up to 30 cubic feet per minute at 100 percent duty cycle. In switching from the Subaru EX40 engine, VMAC says it was able to engineer several improve- ments, including a 23 percent noise reduc- tion at high idle and a 75 percent noise reduction at low idle. The engine is also 15 percent more fuel efficient and offers improved operational performance in hot temperatures and at high elevations, ac- cording to the company. The lighter design enables trucks to save up to 4 percent in fuel, while the compact footprint allows users more space for tools and materials in the back of the truck. The Ditch Witch AT40 horizontal directional drill – built on the same platform as the JT40 introduced earlier this year at ConExpo – features a new two-pipe All Terrain drilling system that the company says provides 33 percent more torque than competitive units to optimize drilling in hard rock. The All Terrain drilling system uses what Ditch Witch calls RockMaster housings that feature "a more robust bearing design, a higher-strength door and high flow capacity," says the company. The modular design makes the housing adaptable in two different sizes of drill bit, allowing a 2.85 and 3.5 regular API connection. The housing has a double-layer seal with high capacity bearings for increased life and reduced maintenance. Ditch Witch says this feature has allowed it to double service time intervals, compared to previous models. More torque for hard rock
