Key Features

eCOOL technology: FS-Curtis' exclusive cooling design maximizes airflow through the package, reducing thermal stress and extending the life of motors, bearings, hoses, and seals by up to 30%.

dBA Shield quiet operation: a centrifugal cooling fan, compartmentalized airflow, and thick laminated sound insulation keep the unit quiet enough for installation close to the work area.

Encapsulated helical twin-screw airend: precision-cut rotor profiles maximize efficiency and deliver long, dependable service life.

Premium-efficiency motor: NEMA Premium TEFC (IP55, Class F) motor protects against dust and heat for a long service life under heavy load.

iCommand control: intelligent load / no-load / modulation control with built-in protection and diagnostics; the optional 7-inch iCommand-Touch+ color touchscreen adds trending, graphing, and higher-level communications.

FS-SmartConnect ready: optional IoT monitoring streams live compressor health and energy data to the cloud for around-the-clock visibility.

Full-synthetic lubrication: FSC-Max synthetic fluid on an 8,000-hour change interval with high-efficiency air/oil separation for clean air and long maintenance intervals.

Integrated 80-gallon receiver: the ASME-rated tank stabilizes pressure and provides ready air storage, mounted and piped as one package.
