The FS-Curtis OL15 Simplex is a premium 15HP oil-less reciprocating air compressor engineered for applications where critical air quality is non-negotiable. Delivering 52.0 CFM at 175 PSI with a 120-gallon horizontal ASME tank, this industrial-grade compressor is the ideal solution for food and beverage production, medical facilities, pharmaceutical manufacturing, electronics assembly, chemical processing, and any environment where even trace amounts of oil contamination could compromise product quality or safety. Available in 230V (model FOL15W15H1S-A3H1XX) or 460V (model FOL15W15H1S-A4H1XX) three-phase configurations, the OL15 combines American-made quality with FS-Curtis's legendary reliability.
100% Oil-Less Air Quality for Critical Applications
At the heart of the OL15 is a 100% dry crankcase design that guarantees absolutely zero oil carryover into your compressed air stream. Unlike traditional lubricated compressors that rely on filtration to remove oil vapor, the FS-Curtis oil-less design eliminates the source of contamination entirely.
- Zero oil contamination — 100% dry crankcase provides oil-less compressed air for critical applications with zero oil carryover, protecting sensitive processes and final products
- Superior cooling performance — Over-sized fan and multiple inter-stage cooling pipes maximize heat transfer for consistently lower discharge temperatures and extended component life
- Environmentally friendly operation — No oil vapor generated by the compressor, eliminating oil changes and costly oil disposal requirements
- Protects downstream equipment — Reduces maintenance costs and equipment damage by eliminating oil contamination throughout your air system
- Lower system costs — Decreases costs and reduces system pressure loss due to reduction of air filtration equipment in the compressed air system
Engineered for Reliability in Demanding Environments
Built for continuous-duty applications, the OL15 features industrial-grade construction designed to deliver years of dependable service in the most demanding environments.
- Low speed pump design — Operates at reduced RPM for long-term reliability, efficiency, and extended service intervals
- 100% duty cycle rated — Engineered for continuous operation without cycling or cooldown periods, perfect for production environments
- Heavy-duty construction — Robust cast-iron crankcase, cylinder, and cylinder head provide long-lasting performance and dimensional stability
- Precision-engineered components — Dynamically balanced ductile iron crankshaft, cast aluminum connecting rods, and sealed pre-greased bearings ensure smooth, reliable operation
Industry-Leading Performance and Design Excellence
Every component of the OL15 has been manufactured to exacting standards to deliver maximum performance, efficiency, and operator comfort.
- Precision-manufactured components — Made to the highest quality standards to provide maximum performance in the most demanding applications
- Low noise operation — Engineered and balanced for reduced sound levels, creating a more comfortable work environment
- High-efficiency valve design — Precision manufactured valves increase air flow, maximize reliability, and require no lubrication
- Advanced thermal management — Air-cooled inter-cooler and balanced flywheel work together to manage heat effectively
