ER-series

ER-series Air compressors provide clean, good quality oil-free compressed air with injected water into compression process. High efficiency The injected water of ER-series is the functions of sealant and coolant. Sealant: Injected water can reduce leakage between rotors and housing, which improved the compressor efficiency by 15% as compared to dry screw compressor Cooling: Injected water is mixed with compressed air and efficiently cool down and dissipate heat generated compression process. The compression is near to isothermal compression. High reliability The start of the art design on airends of ER series provide good air quality perfect performance and high reliability. Oil free air is the trend of global world compressor market. Environment friendly, availability are important issues to customers. Low maintenances intervals Professional engineering design and precise machining with long bearing life. The maintenance interval is enlarged
