2-stage 8-15bar

Two-stage screw compressors for the 8 to 15 bar band, the pressure range most industrial plants and laser installations actually run. Two rotors in series share the compression ratio, which lowers discharge temperature and improves efficiency compared with a single stage at the same pressure. The range includes dual-stage machines at 8, 13 and 15 bar with Hanbell and Baosi air ends, in PM VSD and fixed-speed versions, up to 250 kW. These units suit plants that run continuously at 10 to 13 bar and want to cut specific power rather than add capacity. Tell us the pressure, flow and annual running hours and we will show the comparison.
