Modern HVAC technology faces rising energy costs, limited installation space and increasing performance requirements. With the RadiFlow 630, ebm‑papst introduces a fan solution that addresses these challenges head-on. High airflow rates, significantly improved efficiency in the application, and an exceptionally compact design open up new possibilities for manufacturers of HVAC units, CRAH units and fan wall units (FWU)—especially in data centers.

The RadiFlow 630 was specifically developed for applications with low to medium back pressure. Thanks to the axial flow, high airflow rates can be achieved even in narrow air ducts—without the performance losses typically associated with such designs. In FanGrid concepts, the fan design enables more efficient use of space as well as significant space savings.

At the heart of the concept is a newly developed impeller made of glass-fiber-reinforced composite material. The diagonal impeller with six blades significantly reduces flow losses. The result is up to 10% higher efficiency in the application compared to market competitors—especially in the lower speed range, which is crucial for many HVAC applications.

The highly efficient EC motor is integrated into the impeller in a space-saving design, significantly reducing the fan’s overall length. A specially designed motor suspension distributes forces evenly across multiple mounting points and ensures smooth, quiet operation. The integrated resonance detection protects the bearings during startup and enhances operational reliability in the respective installation scenario.

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 (Power Factor Correction) reduce grid disturbances and minimize the need for external filters and infrastructure components. In combination with integrated EMC filters, international approvals, remote monitoring functions and the compact design, scalable climate control concepts with high power density can be implemented—from space-optimized air handling units to FanGrid systems in modern data centers.
