When your operation demands reliable compressed air with zero downtime, the FS-Curtis CA5+ 120-Gallon Duplex Ultra Pack delivers industrial-grade performance wrapped in a maintenance-friendly package. Designed for automotive, light industrial, and heavy-duty applications, this 5 HP duplex system features two independent pumps that alternate operation to extend pump life while ensuring you always have air available—even during service intervals. With an impressive 37 CFM at 175 PSI and a robust 120-gallon ASME horizontal tank, this compressor handles fluctuating demand with ease. The Ultra Pack configuration means you get factory-installed premium accessories—including an air-cooled aftercooler, automatic tank drain, low oil shutdown protection, and anti-vibration tank isolator pads—all backed by FS-Curtis's industry-leading quality. Available in single-phase 230V and multiple three-phase voltages (200-208V, 230V, and 460V), this Made in USA compressor is built with 100% cast-iron construction and precision components designed to outlast entry-level competitors in the toughest working conditions.
Built for the Toughest Environments
The CA Series from FS-Curtis isn't just built to handle harsh environments—it's engineered to thrive in them. For automotive, light industrial, and other challenging applications, CA Series compressors are built to last. Components are selected based on durability and performance, ensuring that your compressor delivers reliable service in demanding real-world conditions. Precision-machined components and a dedication to materials meant for tough working environments further assure long-term durability. The industrial design delivers the most robust air compressor in its class, providing higher pressures, better efficiency, and longer life than entry-level models, making the CA Series ready to handle the most rugged, heavy-duty applications.
The Ultra Pack configuration means you can easily pair the unit with a standard refrigerated dryer to stop damage from moisture in your air system. Plus, you can rest assured that you'll avoid unnecessary downtime due to excess water in the tank or damage from low oil levels—the system comes factory-equipped with automatic tank drain and low oil shutdown protection.
The Duplex Advantage: Redundancy, Efficiency, and Longevity
Duplex compressors are ideal when there are varying demand levels during operation. By alternating demand across two pumps, a duplex compressor delivers longer pump life and reduced wear on individual components. The redundant pumps ensure you'll always have air, eliminating maintenance downtime. During normal operation, the compressors alternate to balance run time. When system demand spikes, both compressors run simultaneously to meet the load. This duplex design reduces electrical cost by avoiding oversized single-motor installations and eliminates downtime during routine service.
The system includes an alternator control panel mounted with magnetic motor starters and thermal overload protection. A 3-position alternator switch and NEMA-1 rated panel offer flexible control. The duplex configuration is powered by two independent power sources with automatic start-stop control, ensuring seamless, efficient operation.
Most Durable Pump Construction Available
Meticulous material selection ensures long-term reliability. The E57 pump features 100% cast-iron cylinders and cylinder heads, providing unmatched thermal stability and resistance to wear. A long-lasting, corrosion-resistant crankshaft reduces thermal stress for increased reliability. Deep-finned cast-iron cylinders and cylinder heads promote cool operation even under continuous demand. The slow-turning pump design significantly increases pump life compared to faster-running competitors.
Industrial-grade main roller bearings are precision-fit to support all rotating parts. A high-flow, heavy-duty stainless-steel valve system delivers more CFM per horsepower than standard valves. The robust intercooler increases compressor efficiency, while the metal intake filter/silencer is superior to plastic alternatives found on cheaper models. A heavy-duty stamped-steel belt guard meets OSHA approval standards, and suction valve head unloaders support continuous-run applications.
Ultra Pack: Complete System, Maximum Value
The CA Series compressors are already an outstanding value, and an FS-Curtis Ultra Pack gives you even more. An Ultra Pack includes a CA Series compressor fully packaged with the most common options and accessories. You'll save money and time by getting it all in one package, and you'll be assured of increasing air quality while reducing maintenance needs. Industry-leading five-year bumper-to-bumper warranty available—talk with your FS-Curtis representative for more details.
