In 2015, Xi'an Ultrafiltration made a grand comeback in the compressed air sector. The zero-gas-consumption adsorption dryer emerged unexpectedly. The energy-saving rate was as high as 60-95%.

      2015 was the concluding project of Xi'an Ultrafiltration. A new large-scale test bench with a 60m3 blower and external heating, which consumed zero gas, passed the full-flow test and was supplied in batches to 22 units at one time.

      2016 saw Xi'an Ultrafiltration continuing its journey: natural gas, compressed air, high-pressure military gas sources, and industrial gases supported a large sales platform. No matter how turbulent the market was, the bright spot would always be there in the East.
