The 2SY series is a high-performance two-stage liquid ring compressor/vacuum pump engineered for demanding industrial environments. By utilizing a dual-stage series structure, it achieves superior compression ratios, 15-20% higher energy efficiency than single-stage models, and safe handling of flammable or corrosive gases. With a maximum discharge pressure of 0.8MPaG and versatile dual-functionality (vacuum and compression), it is the premier choice for petrochemical, power, and mining applications requiring reliability and safety.
