New version RadiPac centrifugal fan
23rd March 2026
GERMANY: EBM‑Papst has announced a third generation version of its RadiPac centrifugal fan in a metal housing.
With high-performance metal impellers, optimised manufacturing processes and intelligent drive technology, these fans are said to meet increasing demands for energy efficiency, fire safety and reliability—both in North America and Asia.
The new series was specifically designed for HVAC systems, precision air conditioning units, electronics cooling, cooling towers as well as other refrigeration and air conditioning applications.
Modernized sheet metal forming and joining processes produce high-performance impellers that neither melt nor emit smoke in the event of a fire. Greater strength and improved efficiency result from a 3D-formed blade geometry with tight manufacturing tolerances. Hybrid designs combining a metal impeller and a plastic inlet nozzle with a smaller air gap can be manufactured upon request for even greater efficiency.
The new fans are available in several sizes with impeller diameters ranging from 280mm to 800mm. They cover a power range from 170W to 24kW with an airflow of up to 50,000m³/h (free discharge) and a pressure increase of approx. 2,500Pa.
The mounting plate and many peripheral components have been designed to allow for easy replacement of older models. Existing components such as inlet grilles and inlet nozzles remain compatible, facilitating universal use and simple integration into existing systems.
The series offers both standard and compact versions, making it ideally suited for space-constrained applications.
The automatic resonance detection integrated into the RadiPac protects the bearings during startup, reduces failures and thereby increases reliability, the company states. All fans support 0–10VDC or MODBUS RTU, feature EMC filters and meet all relevant EU and UL certifications. Additionally, remote monitoring of the fans is possible, as is the simple integration of external sensors into the fan control system.
