The FS-Curtis OL15 is the ideal reciprocating oil-less air compressor for applications where critical air quality is required such as food and beverage, medical, chemical processing, pharmaceutical, electronics, and more. Delivering 52.0 CFM at 175 PSI, this robust 15HP base-mounted unit features the proven TW150 pump with 3 cylinders and a 100% dry crankcase that provides completely oil-free compressed air with zero oil carryover. Available in 230V/3/60Hz (FOL15W15BXS-A3H1XX) or 460V/3/60Hz (FOL15W15BXS-A4H1XX), the OL15 is engineered for continuous operation with a 100% duty cycle and unmatched reliability in the most demanding industrial environments.
Oil-Less Air Quality for Critical Applications
When your operation demands absolute air purity, the FS-Curtis OL15 delivers. The 100% dry crankcase design provides oil-less compressed air for critical applications with zero oil carryover, protecting your products, processes, and downstream equipment from contamination.
- Zero oil carryover ensures 100% oil-free compressed air for sensitive applications
- Over-sized fan and multiple inter-stage cooling pipes maximize heat transfer for lower discharge temperature and improved efficiency
- Environmentally friendly operation with no oil vapor generated by the compressor
- Eliminates oil changes and oil disposal costs, reducing maintenance expenses and environmental impact
- Protects downstream equipment from oil contamination and reduces maintenance costs
- Decreases system costs and reduces pressure loss by minimizing the need for air filtration equipment in the compressed air system
