rotary screw air compressors

firstAir German Series of FS Curtis GmbH and offers a wide range of air cooled rotary screw compressors with a nominal motor power from 4 to 250 kW and operating pressure from 5 to 16 bar(g). For this purpose, a new range of airends with high performance has been developed, designed and produced which, together with our high-quality thermostatic valves, intake valves and separators, contribute to the reliability and long lifetime of the product. Thanks to our highly efficient airends in conjunction with IE3 electric motors, the screw compressors achieve a high technological standard and high efficiency. Thanks to the new high efficiency air-ends linked with the IE3 electrical motors which are just as powerful, a high technological standard and a high efficiency are achieved. High environmental and energy saving standards are also respected when developing new products

FS-Curtis rotary screw air compressors offer businesses the best combination of time-proven designs and technologies. Our rotary screw compressors also ensure the highest levels of reliability, efficiency, and productivity available.

9-12Bar, Oil Injected Transport Compressor Single stage, oil injected screw compressor specially made for transport application. The modular design and IPM motor ensures creative utilization of space and high operational efficiency.

55-250kW DIRECT ROTARY SCREW AIR COMPRESSORS Our most energy-efficient air compressor to date, the NxHE Series compressors use patented two-stage airend technology to provide efficient operation with outstanding durability and offer the lowest life-cycle cost of any compressor on the market. Description TWO-STAGE COMPRESSION: SETTING THE STANDARD FOR ENERGY EFFICIENCY Compared to single-stage rotary screw compressors, a two-stage is much closer to isothermal compression. This is achieved by injection of fresh oil between the stages which reduces the inlet temperature to the second stage. This lower inlet temperature increases efficiency by reducing the compression ratio between the stages. In addition, leakage between the rotor seals is significantly reduced resulting in outstanding volumetric efficiency. Two-stage air compressors are closer to the ideal isothermal compression: • Reduced leakage increases volumetric efficiency • Saves 10-15% of energy compared to single-stage compressors • Increases flow 10-15% compared to single-stage compressors • Lower pressure differential increases efficiency and reliability • Low heat load • Easy maintenance and service • Lowest life-cycle cost of any compressor on the market eCOOL® TECHNOLOGY The ultimate in system protection and reliability • Protects critical components from compressor-generated heat • Compartmentalized air flow design and oversized aftercooler • Extends component life and reduces downtime ENERGY EFFICIENT TWO-STAGE AIREND Energy-saving and Eco-friendly • Patented airend design integrates the first and second stage rotors into one airend • Oil is injected between the first and second stages to cool the air and optimize efficiency • Splitting the compression cycle into Two-stages reduces the axial and thrust loading to which improves service life of airend and bearings • Two-stage compression significantly reduces noise EFFECTIVELY INTEGRATED OVERALL DESIGN Designed for low cost of ownership, easy service & little down time • Safe, efficient air filter system • Independent bearing lubrication • High efficiency, easy-to-maintain oil separator • IE3 high efficiency motor • End face sealed to prevent leakage • Connections utilize o-ring face seals for leak–free performance • Asbestos-free gaskets protect operator health

7-12 Bar, Direct Driven, Fixed & Variable Speed Rotary Screw Compressor Compact in design, robust in power, the smooth, quiet operation of the NX is ideal for a wide variety of applications ranging from auto body shops to light industrial. High-Performance, Legendary Reliability Stable air pressure, steady airflow, and quieter, continuous-duty operation are just a few of the advantages you get with FS-Curtis rotary screw compressors. These smart, compact units also offer better air quality with less oil carryover than reciprocating models. Intuitive controls and diagnostics make them easy to use and service, too. It all adds up to an extremely reliable machine that can run 100% continuous duty, delivering more airflow and better efficiency in a space-saving design — making the Nx Series ideal for automotive, light industrial, and other applications that require reliable performance in demanding conditions. Nx 15-90 kW Features dBA SHIELD NOISE REDUCTION Designed for quiet operation. Integration of centrifugal blower and drive motors make for extremely smooth and quiet operation Extra-thick sound insulation reduces noise Can be installed in applications where a quiet setting is important eCOOL® TECHNOLOGY The ultimate in system protection and reliability. Protects critical components from compressor-generated heat Extends component life and reduces downtime Compartmentalized air flow design and standard aftercooler QUALITY COMPONENTS Built to the highest levels of dependability and reliability. Standard TEFC motor protects compressor from surrounding dirty air, increasing the efficiency and prolonging the life of the motor. Spin-on air/oil separator allows for quick maintenance and results in one-to-three PPM oil carryover. This translates into lower make-up oil costs and higher quality compressed air. SUPERIOR PACKAGE DESIGN Designed for low cost of ownership and easy service. Space-saving design Pulsation-free air 100% continuous duty Extended service intervals More CFM per horsepower Improved air quality Energy efficiency at full load delivers more air for the mone integrated into a smaller footprint Exclusive FS-Curtis airends utilize the latest rotor profile to maximize efficiency Optional DemandSmart Energy Management System Ideal combination of variable speed drive, controller, and drivetrain. The VSD – time proven directly coupled design – offers faster response and greater operational efficiency Variable operation slows airend speed, which lowers energy costs and reduces wear With DemandSmart technology, the VSD enhances quality by stabilizing air pressure at 1 psi increments Built-in DC Choke protects against harmonic disturbances and eliminates the need to source additional corrective devices iCommand Controller is intuitive and easy to use while precisely delivering compressed air usage.
