The Sullair 185 has been redesigned to accommodate a Tier 4-Final engine: a 1.8L, 49-horsepower Kubota. The air end is direct-driven, and a 27-gallon tank provides almost 10 hours of use, the company says. Rated pressure is 100 psig; working weight is 2,200 pounds; and it measures 131 inches long, 59 inches wide, and 54 inches high.
