Centrifugal compressor DK-GF180A-T

airDCstationary

Overview
The DK-GF180A-T is a two-stage air compressor integrating a VNT (variable nozzle turbine) energy-recovery stage for fuel-cell air supply. It operates across 15–245 g/s, reaches a maximum pressure ratio of 3.8 and can improve energy efficiency by up to 30% while meeting vehicle integration and IP67 environmental protection requirements.
