Centrifugal compressor DK-GF180B

airDCstationary

Overview
The DK-GF180B is a two-stage fuel cell air compressor designed without an energy-recovery turbine. It delivers an oil-free airflow of 13–245 g/s, driven by a 30 kW motor, with a maximum pressure ratio of 3.5 and IP67 protection for integration into industrial fuel cell systems requiring precise airflow control.

Key features

• Two-stage supercharging architecture for wide operating range
• Oil-free operation using air suspension bearings
• Flow control range: 13–245 g/s
• Speed range: 30,000–95,000 rpm
• Voltage: 450–750 VDC; motor up to 30 kW
• Maximum pressure ratio: 3.5
• Protection level: IP67 for harsh environments
• Start–stop endurance: 300,000 cycles

Applications
Integration in stationary and mobile fuel cell systems that require oil-free air supply, wide flow modulation and environmental protection (IP67). Suitable for manufacturers and system integrators working on fuel cell stacks and balance-of-plant components.
