FS-Curtis

What FS-Curtis does

FS-Curtis, operating legally as Curtis-Toledo, Inc., is a St. Louis, Missouri-based industrial air compressor manufacturer founded in 1854, making it one of the longest-tenured U.S. industrial equipment brands. The company designs and builds rotary screw compressors (5–350HP, including the award-winning NX and NXHE Two-Stage series), oil-free compressors certified to ISO 8573-1 Class 0 (ECO-Pure, ECO-Rotary, ECO-Scroll, OL Series), reciprocating compressors (produced since 1897), rotary screw vacuum pumps, oil-free blowers, and a full air treatment accessory line (RN refrigerated dryers, CF filtration, oil-water separators). Its technology stack rests on a patented two-stage airend (NXHE), proprietary eCool thermal management, an exclusive precision-cut rotor airend design, the iCommand-Touch+ HMI controller, and the SmartConnect 2.0 cloud-based remote monitoring platform with predictive maintenance alerts.

The business operates a 100% channel model: FS-Curtis does not sell direct to end users but routes all sales, installation, service, and parts through an authorized global distributor network of factory-trained partners, supported by a dedicated distributor portal, a public distributor finder, and an annual Platinum Channel Partner program. Geographic reach covers the United States (headquarters and manufacturing in St. Louis) plus four Asia regional markets — Malaysia, Thailand, Indonesia, and India — each with localized websites. End markets span general manufacturing, food and beverage, pharmaceutical, medical, oil and gas, mining, cement, automotive, packaging, and PET bottle-blowing.

Revenue mechanics combine one-time hardware sales of packaged compressor systems (5HP–350HP), recurring aftermarket sales of OEM parts and the FSC-Max Cool synthetic lubricant, financing arrangements offered through the company, and air treatment accessories. The NXGEN extended warranty (5-year major components, 10-year airend) and SmartConnect monitoring ecosystem create retention dynamics around the installed base. The company is privately held, with 251–500 employees, no disclosed institutional ownership, no funding rounds in the data, and a noted sister-company relationship with FS-Elliott (co-exhibition at industry events such as Reliable Plant 2026).
