Sullair 185DPQ-KU – Tier 4 Final Portable Air Compressor (185 Series)

Sullair 185DPQ-KU | 185 CFM at 100 PSI Industrial Delivery Analysis

The Sullair 185DPQ-KU is a heavy-duty portable rotary screw compressor engineered for high-volume civil engineering and construction applications. Powered by a 49 HP Kubota Tier 4 Final diesel engine, this unit is optimized for volumetric efficiency to deliver a consistent 185 CFM airflow. It serves as an essential mobile power plant for utility crews and road contractors who require a 100 percent duty cycle for operating multiple pneumatic breakers or sandblasting equipment in the most demanding outdoor job site environments.

The direct-drive air-end is designed for maximum thermal stability, ensuring efficient power transfer and reduced mechanical vibration during continuous operation. Due to the high-demand nature of diesel-powered rotary systems, regular manual oversight of the standard drain and oil levels is required to protect the precision air-end and maintain long-term reliability. The integrated low oil protection system provides a critical automated safeguard for the Kubota engine, preventing catastrophic friction damage while the large 27-gallon fuel capacity supports extended operational shifts without refueling.
