ebm-papst adds 1030 mm and 1250 mm single-blade AxiBlade fans for high-airflow, low-noise refrigeration and data center systems

ebm-papst has unveiled two new axial fans that push its single-blade AxiBlade concept into the 1030 mm and 1250 mm diameter classes, targeting applications where high cooling capacity must coexist with low noise and high operational reliability. The AxiBlade.S.Perform (1030 mm) and AxiBlade.S (1250 mm) were presented at Chillventa and are intended for chillers, condensers, recoolers, data center cooling, greenhouses, livestock barns, and transformer cooling.

System-level tuning instead of a standalone fan

Rather than specifying the impeller in isolation, ebm-papst matches the impeller, EC motor, shroud, electronics, and other components to the target application. The single-blade design uses composite blades mounted on a hub ring; blades can be set at various angular positions at the factory, allowing airflow, pressure build-up, efficiency, and acoustics to be tailored to the customer's system.

Key specifications

• AxiBlade.S.Perform, 1030 mm – up to 50,000 m³/h (free-blowing) or 32,000 m³/h at 330 Pa; composite-material wall ring; designed for high airflow, flexible installation, and low noise.
• AxiBlade.S, 1250 mm – up to 58,000 m³/h (free-blowing) or 41,000 m³/h at 150 Pa; sheet-metal wall ring with protective cage; suited to large chillers, condensers, recoolers, and demanding data center applications.

Electrical and digital features

Both sizes are available with high-performance EC motors rated up to 8 kW, designed for ambient temperatures from −40 °C to +70 °C depending on the model, and offered with passive or active power factor correction. A MODBUS interface is provided as standard, enabling integration into ebm-papst's NEXAIRA digital ecosystem. Through NEXAIRA, operators gain access to operational data, improved transparency on efficiency and reliability, and digital services such as demand-based control and predictive maintenance.

Regulatory compliance and OEM support

The expanded AxiBlade series meets all requirements of the Ecodesign Directive and the Fan Regulation (ErP 2026). ebm-papst states that it supports OEMs with documentation, verification, and certification for the new models.
