The FS-Curtis OL7.5 Duplex oil-less air compressor delivers 46.2 CFM at 175 PSI with zero oil carryover, making it the ideal solution for applications where critical air quality is non-negotiable. Featuring a duplex configuration with dual 7.5HP motors (available in 230V or 460V 3-phase), a 120-gallon horizontal ASME tank, and a TW75 3-cylinder pump, this compressor is engineered for industries like food and beverage, medical, pharmaceutical, chemical processing, and electronics where contamination-free compressed air is essential. Built with 100% dry crankcase technology, the OL7.5 Duplex ensures clean air, reduces maintenance costs, and operates with 100% duty cycle for continuous, reliable performance in the most demanding environments.


Oil-Less Air Quality for Critical Applications

When your operation demands absolutely oil-free compressed air, the OL7.5 Duplex delivers. The 100% dry crankcase design provides compressed air with zero oil carryover, protecting downstream equipment, eliminating contamination risks, and reducing maintenance costs associated with oil-flooded systems.

  • 100% dry crankcase provides oil-less compressed air for critical applications with zero oil carryover
  • Over-sized fan and multiple inter-stage cooling pipes maximize heat transfer for lower discharge temperature
  • Environmentally friendly with no oil vapor generated by the compressor. Eliminates oil changes and oil disposal costs
  • Protects downstream equipment and reduces maintenance cost
  • Decreases costs and reduces system pressure loss due to reduction of air filtration equipment in the compressed air system

Reliability Engineered for Your Critical Application

Built to run continuously without compromise, the OL7.5 Duplex features a low-speed TW75 pump with 3 cylinders and a cast iron crankcase designed for long-term durability. Every component is precision-engineered to handle the most demanding production schedules.

  • Low speed pump for long-term reliability and efficiency
  • 100% duty cycle for continuous operation without interruption
  • Robust cast-iron crankcase, cylinder, and cylinder head for long-lasting performance
  • Dynamically balanced ductile iron crankshaft and cast aluminum connecting rods
  • Sealed pre-greased bearings and self-lubricated guide rings require no maintenance

Industry-Leading Performance and Precision

The FS-Curtis OL7.5 Duplex is designed to deliver maximum performance in the most demanding applications. With precision-manufactured valves, aluminum pistons, and air-cooled inter-cooler technology, this compressor maximizes efficiency and minimizes downtime.

  • Components made to the highest quality and precision to provide maximum performance in demanding applications
  • Designed for low noise level operation
  • Precision-manufactured valves (requiring no lubrication) increase air flow and maximize reliability
  • Alternate panel for duplex operation ensures seamless coordination between compressor units
  • Slow V-belt drive and balanced flywheel for smooth, efficient power transmission

Key Highlights

  • 46.2 CFM at 175 PSI – powerful air delivery for demanding applications
  • 120-gallon horizontal ASME tank with duplex configuration – extended run time and redundancy
  • Zero oil carryover – 100% dry crankcase technology ensures contamination-free compressed air
