Product Description
Master high-intensity industrial tasks with our Professional Mobile Diesel Screw Air Compressor Series. Engineered for elite performance in the most demanding environments, the SAC125 and SAC185 represent the pinnacle of portable pneumatic power. Driven by a high-torque, fuel-efficient diesel engine, these rotative screw compressors provide a continuous and stable air supply that piston compressors simply cannot match.
The series offers a versatile range with the SAC125 delivering 120 cfm (3.5 m³/min) and the SAC185 providing a massive 185 cfm (5.2 m³/min) at a consistent 7 bar (100 psi) working pressure. Built into a heavy-duty, sound-attenuated canopy with easy-access maintenance panels, these units are mounted on a rugged trailer chassis for effortless towing between job sites. Whether you are powering heavy-duty jackhammers, large-scale sandblasting equipment, or remote mining tools, this mobile compressor series delivers the industrial-grade reliability and extreme durability required for high-productivity infrastructure and engineering projects.
