NxHE Series Two-Stage
125-350HP / 90-260kW

FS-CURTIS’s 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. Compared to single-stage 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.
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
• Lowest life-cycle cost of any compressor on the market
