ebm-papst launches RadiFlow 630 fan for HVAC and data centers

ebm-papst has introduced the RadiFlow 630, a compact fan solution with a diameter of 630 mm for HVAC units, CRAH units and fan wall units, including applications in data centers. The company says the fan is designed to address rising energy costs, limited installation space and increasing performance requirements.

The RadiFlow 630 was developed for applications with low to medium back pressure. Its axial flow design enables high airflow rates in narrow air ducts, while FanGrid concepts can use the fan design for more efficient use of space and significant space savings.

The fan uses a newly developed impeller made of glass-fiber-reinforced composite material. The diagonal impeller has six blades and is designed to reduce flow losses, delivering up to 10% higher efficiency in the application compared with market competitors, especially in the lower speed range.

The EC motor is integrated into the impeller to reduce the fan’s overall length. A specially designed motor suspension distributes forces across multiple mounting points for smooth, quiet operation, while integrated resonance detection protects the bearings during startup.

RadiFlow fans support demand-based speed control via 0–10 VDC or MODBUS RTU and are designed for continuous operation in HVAC and data center applications. Variants with Active PFC reduce grid disturbances and minimize the need for external filters and infrastructure components, while integrated EMC filters, international approvals, remote monitoring functions and the compact design support scalable climate control concepts with high power density.
