Product catalog summary

About Blauberg Group
Blauberg Group, based in Munich, Germany, specializes in energy-efficient ventilation equipment, including domestic and industrial fans. The company emphasizes innovative technology, contemporary design, and traditional German quality, with R&D centers in Germany, Ukraine, and Poland.

Fan Motors
The catalogue describes two main motor types: asynchronous and EC motors. Asynchronous motors are known for their simple design and resistance to mechanical overloads, while EC motors offer high efficiency, energy savings, and smart functions like temperature and pressure-based fan control.

Designation Key
A systematic designation key helps identify fan models based on features such as impeller diameter, number of poles, voltage, and modifications like grid presence and impeller material.

AC Axial Fans
The catalogue provides specifications for AC axial fans with impeller sizes of 200 mm to 350 mm, detailing technical data such as voltage, frequency, speed, power input, sound pressure level, and ambient temperature. These fans are designed for continuous operation with self-resetting motor protection.

Technical Features and Specifications
Each fan model includes details on impeller material, rotation direction, protection type, insulation class, and bearing type. Diagrams and tables illustrate performance curves and dimensions, aiding in installation and selection.

Conclusion
Blauberg's axial fans are efficient and reliable, suitable for various applications with customizable features. The catalogue offers comprehensive technical details for selecting appropriate fan models.

FAN MOTORS THE MOTORS ARE POWERED BY DIRECT OR ALTERNATING CURRENT. A direct current motor is powered by a direct power supply. ALTERNATING CURRENT MOTORS HAVE TWO TYPES: Synchronous electric motors are alternating current motors with a rotor that rotates synchronously with An alternating current motor is powered by an alternating power supply. Asynchronous electric motors are alternating current Alternating current motors are the most widely used motors because the basic electric grid in the country has alternating power supply. motors with the magnetic field frequency exceeding the motor rotation...

EC motors The electric motor with high-efficient EC motor is a synchronous direct current motor driven by an electronic commutating unit (controller). It has no friction and wearing parts as a collector or brushes, unlike the standard motor. The function of these parts is performed with the maintenance-free electronic circuit of the EC controller. The EC technology is the state-of-the-art method for arrangement of energy saving and high efficient ventilation. The energy demand of EC motors is by 50% less as compared to standard motors and efficiency reaches 90%. These new electric motors are...
