Centrifugal compressor DK-GF300A-T

airDCstationary

Overview
The DK-GF300A-T integrates two-stage compression with a VNT turbine energy-recovery system for air supply to fuel cell systems. It operates over 20–340 g/s, achieves a maximum pressure ratio of 4.0 and is specified to enable up to 30% energy-efficiency improvement in 150–200 kW fuel cell systems. Designed for system integration with IP67 protection and air suspension bearings.
