NXHE Series

The FS-Curtis NxHE Series two-stage rotary screw air compressors are heavily relied upon in industry for their legendary reliability and highly energy efficient operation. NxHE splits the compression process into two stages and removes heat of compression in between. The result is less input horsepower required to generate the same flow as single stage. Splitting the compression process over two stages also reduces the compression ratio, which results in lower thrust loads on the bearings and longer air end life. NxHE two-stage compressors offer unparalled energy efficiency in a reliable long life industrial air compressor - making it ideal for high flow base load industrial applications.

More acfm per horsepower than single stage equals power savings, and the ability to select a smaller compressor Lower specific power/higher Isentropic Efficiency than single stage equals power saving Two-stage air end life is considerably longer than its single stage counterpart due to reduced thrust loads on bearings (lower compression ratio in each stage) Over / Under design allows for inter-stage cooling which removes heat of compression and improves overall efficiency Independent bearing lubrication system delivers oil to critical wear points to extend air end life
