The FS-Curtis OL10 Duplex is the ideal reciprocating oil-less air compressor for applications where critical air quality is absolutely required. Industries such as food and beverage, medical, chemical processing, pharmaceutical, electronics, and more demand zero oil contamination — and this 10HP duplex system with its 200-gallon horizontal ASME tank delivers precisely that. Featuring dual TW100 pumps with 3-cylinder design, the OL10 Duplex produces 71.2 CFM at 175 PSI, providing substantial compressed air capacity with complete oil-free reliability. Available in both 230V/3-phase (model FOL10W10D2S-A3H1XX) and 460V/3-phase (model FOL10W10D2S-A4H1XX) configurations, this American-made compressor is engineered for demanding environments where air purity, continuous operation, and long-term performance are non-negotiable.
Oil-Less Air Quality for Critical Applications
The FS-Curtis OL Series sets the standard for oil-less compressed air. The 100% dry crankcase provides genuinely oil-less compressed air for your most critical applications with zero oil carryover. This eliminates the risk of oil contamination in your products, processes, or equipment — an essential requirement for industries where even trace amounts of oil can cause product rejection, equipment damage, or safety issues.
An over-sized fan and multiple inter-stage cooling pipes maximize heat transfer for lower discharge temperatures, ensuring consistent, cool, and dry compressed air. The unit features an air-cooled inter-cooler that further reduces air temperature between compression stages, optimizing performance and reliability.
This system is environmentally friendly with no oil vapor generated by the compressor. You eliminate oil changes, oil disposal costs, and the environmental liability that comes with oil-lubricated compressors. The oil-less design also protects downstream equipment, reduces maintenance costs, and decreases operating expenses by reducing the need for extensive air filtration equipment in your compressed air system. Less filtration means reduced system pressure loss and lower energy costs.
Reliability Engineered for Continuous Operation
When your critical application demands uninterrupted compressed air, the OL10 Duplex delivers. Featuring a low-speed pump for long-term reliability and efficiency, this compressor is designed for 100% duty cycle continuous operation. Unlike compressors that need frequent rest periods, the OL10 can run all day, every day, without compromise.
The foundation of this reliability is the robust cast-iron crankcase, cylinder, and cylinder head. These heavy-duty components provide long-lasting performance even in the most demanding industrial environments. The dynamically balanced ductile iron crankshaft and cast aluminum high tensile strength connecting rod work together to minimize vibration and maximize durability. Sealed pre-greased bearings eliminate the need for routine bearing maintenance, while the balanced flywheel ensures smooth, quiet operation.
The compressor features aluminum pistons with self-lubricated guide rings and compression rings engineered with advanced materials and coatings. The precision-machined valves require no lubrication, further reducing maintenance requirements and ensuring oil-free operation throughout the entire compression pathway.
Industry-Leading Performance and Precision
Every component in the FS-Curtis OL10 has been manufactured to the highest quality and precision standards to provide maximum performance in the most demanding applications. The precision-manufactured valves increase air flow and maximize reliability, ensuring optimal CFM output and extended service life.
Noise control is a priority in this design. The compressor is engineered for low noise levels, featuring an intake filter with silencer that reduces operational sound without sacrificing performance. This makes the OL10 suitable for installation in facilities where noise pollution must be minimized.
The NEMA-designed electric motor delivers reliable power through a slow V-belt driver, which reduces rotational speed at the pump for enhanced efficiency and longevity. The duplex configuration features an alternate panel for controlling both compressors, while safety and control are managed by a UL pressure switch and magnetic starter system. An OSHA-approved belt guard ensures operator safety during operation and maintenance.
Complete System with ASME Tank and Safety Features
The OL10 Duplex is mounted on a substantial 200-gallon horizontal ASME tank, providing ample air storage for consistent pressure delivery and reduced compressor cycling. The tank is equipped with a manual tank drain valve for easy moisture removal, while copper discharge piping ensures efficient air transfer from the pump to the tank.
Safety features include an ASME safety relief valve, ASME air service valve, and an air pressure gauge for easy monitoring of system pressure. The unit comes with isolation pads (shipped loose) to minimize vibration transmission to the floor and reduce operational noise in your facility. With a 1-inch NPT connection, the compressor integrates easily into existing compressed air distribution systems.
The entire unit measures 104" L x 35" W x 66.8" H and weighs 1,985 lbs, providing a stable, professional-grade installation. With its robust construction, comprehensive feature set, and Made in USA quality, the FS-Curtis OL10 Duplex is the premium choice for facilities that demand oil-free compressed air with uncompromising reliability.
