The FS-Curtis OL5 Series Duplex Oil-less Air Compressor represents the pinnacle of clean compressed air technology for critical applications. This 5HP duplex system with a 120-gallon ASME horizontal tank delivers 24.6 CFM at 175 PSI, providing oil-free air quality essential for food and beverage production, medical facilities, pharmaceutical manufacturing, chemical processing, electronics assembly, and other industries where contamination is simply not an option. Available in 230V/3/60Hz (model FOL05W50D1S-A3H1XX) and 460V/3/60Hz (model FOL05W50D1S-A4H1XX) configurations, this duplex unit features two pumps for redundancy and increased capacity, ensuring continuous operation for your most demanding processes.
Oil-Less Air Quality You Can Count On
The OL5 Duplex utilizes a revolutionary design that guarantees absolutely zero oil carryover in your compressed air system. The 100% dry crankcase design provides truly oil-less compressed air for critical applications where even trace amounts of oil contamination could compromise product quality, safety, or compliance.
An over-sized fan and multiple inter-stage cooling pipes maximize heat transfer throughout the compression process, resulting in significantly lower discharge temperatures. This enhanced cooling not only protects your equipment but ensures consistently clean, cool air delivery to your production line.
Operating an oil-less system is not only better for your product—it's better for the environment. This compressor is environmentally friendly with no oil vapor generated during operation. You'll eliminate the recurring costs and hassles associated with oil changes and oil disposal, while protecting sensitive downstream equipment from contamination. The reduction in required air filtration equipment also decreases system pressure loss and lowers your overall operating costs.
Built for Reliability in Critical Applications
When your production line depends on continuous compressed air, downtime is not an option. The OL5 Duplex features a low-speed VW50 pump designed for long-term reliability and efficiency. The slower operating speed reduces wear on critical components, extending service life and minimizing maintenance requirements.
This system is engineered for 100% duty cycle continuous operation, meaning it can run all day, every day, without interruption. The robust cast-iron crankcase, cylinder, and cylinder head construction ensures long-lasting performance even in the most demanding industrial environments. The duplex configuration provides built-in redundancy—if one pump requires service, the second pump keeps your operation running.
Industry-Leading Performance and Engineering
Every component in the OL5 Series has been manufactured to the highest quality standards and precision tolerances to deliver maximum performance in demanding applications. Precision-manufactured valves that require no lubrication increase air flow while maximizing reliability and service life.
The compressor is designed for low noise operation, making it suitable for installation in facilities where noise levels must be controlled. The dynamically balanced ductile iron crankshaft, balanced flywheel, and isolation pads work together to minimize vibration and reduce operational noise, creating a more comfortable work environment.
Safety and compliance are built into every aspect of this compressor. Features include an OSHA-approved belt guard, ASME safety relief valve, UL pressure switch, and an ASME-certified 120-gallon horizontal tank. The duplex configuration includes an alternator panel for coordinated pump operation, while the slow V-belt drive ensures smooth, efficient power transfer.
