Centrifugal fans for a wide range of applications
Rosenberg offers a wide range of centrifugal fans. In addition to different housing designs, Rosenberg radial fans are available in both single-sided and double-sided suction versions. The fans are also available with different drives. Energy-saving EC external rotor motors, conventional AC external rotor motors and IEC standard motors are used.
Centrifugal fans with
backward curved impellers
EC centrifugal fans with backward curved impellers
This series exclusively uses energy-efficient EC external rotor motors for the drive. The high-performance radial fans with backward curved blades have been specially developed for use in modern ventilation and air conditioning units and are suitable for conveying air with low dust content and slightly aggressive gases and vapours. The sizes correspond to the standard number series R20 according to DIN 323.
Centrifugal fans with backward curved impellers
These centrifugal fans have been specially developed for use in modern ventilation and air handling units and are suitable for conveying air with low dust content and slightly aggressive gases and vapours. The sizes correspond to the standard number series R20 according to DIN 232.
Centrifugal fans with standard motors and backward curved impellers
The high-performance centrifugal fans in the EHN.. series are suitable for conveying clean or low-dust air and slightly aggressive gases and vapours. They are not gas-tight. The permissible conveying medium temperature is between -30°C and 60°C.

High-performance centrifugal fans with slip characteristics
By using specially designed external rotor motors with high rotor resistance in combination with forward-curved centrifugal impellers, we have developed a series of centrifugal fans with extremely high slip characteristics. The external rotor motor adapts its operating behaviour to the respective loads. This causes the speed to change depending on the total pressure. This is particularly advantageous when resistances change during operation, e.g. when filters become dirty, duct systems are switched on and off, and for clean room technology.
Centrifugal fans with standard motor and forward curved impellers
The high-performance ERN.. type centrifugal fans are suitable for conveying clean or low-dust air and slightly aggressive gases and vapours. They are not gas-tight. The permissible conveying medium temperature is between -30°C and 60°C.
