The FXT Air Series (FXT30, FXT50 and FXT65) of air excavators from Ditch Witch provides both air and hydroexcavation capabilities for digging, potholing and locating utilities on below-grade job sites. All three models use a PTO-driven air compressor for efficient power transfer and increased productivity. The filtration system utilizes a cyclonic separator to remove fine particles before reaching the vacuum system. Operators can monitor and command all components using an electronic controller that displays system parameters. 800/654-6481; www.ditchwitch.com.
