Blauberg Axial Fans And Tangential Blowers: Technical Breakthroughs in Segmented Scenarios

Technological innovation in ventilation equipment is often reflected in the ultimate response to the needs of segmented scenarios. Blauberg Motor's axial fans and tangential blowers series, targeting the special requirements of industrial environments and household appliance fields respectively, have achieved precise matching between performance and scenarios through material innovation and structural optimization, realizing the leap from "scenario adaptation" to "scenario leadership".

The core competitiveness of the axial fan series lies in "extreme environment adaptability". Its impellers adopt a dual-material scheme: metal welded impellers undergo high-temperature aging treatment, which can withstand temperature fluctuations from -40℃ to 200℃, making them suitable for industrial scenarios such as metallurgy and chemical industry; glass fiber-reinforced plastic integrally formed impellers improve corrosion resistance while reducing weight by 30%, which are particularly suitable for humid marine engineering or food processing workshops. The driving motor is equipped with an energy-saving EC intelligent motor, combined with maintenance-free ball bearings, with a design life of 60,000 hours - equivalent to continuous use for 20 years when operating 8 hours a day. Through the analysis of the flow field of air duct pressure distortion, the R&D team optimized the gap parameters between the wind deflector and the impeller, reducing the air flow loss between the rotor and stator by 15%, and significantly improving the wind pressure stability under the same power. After applying this series of fans in a tunnel project, the operating noise was reduced by 8dB(A) compared with traditional products under the working condition of wind speed 12m/s, which was highly recognized by the construction party.

The tangential blower series focuses on "invisible empowerment in household appliance scenarios". With a cross-flow impeller with a diameter of 30~80mm as the core, the maximum length of a single segment can reach 650mm, and the maximum length of multi-segment splicing can reach 1190mm, which can adapt to various household appliance sizes from ovens to air conditioners. Its aluminum die-cast frame is combined with anti-vibration rubber damping pads to control operating vibration below 0.1mm/s, solving the noise problem caused by resonance between traditional fans and household appliance shells. The application of a three-core sine wave commutation circuit reduces the electromagnetic noise of the motor during operation to 28dB(A) (at a distance of 1.5m), equivalent to the quiet level of a library environment.

In response to the requirements of the home appliance market for appearance and safety, the tangential blower adopts an ultra-thin design (only 30mm at the thinnest), combined with an anti-vibration rubber mechanical soft connection system, perfectly integrating into the slim bodies of fireplaces, microwave ovens, air purifiers and other products. The moisture-proof and waterproof version has passed IP44 protection certification and can still operate stably in humid environments such as bathroom heaters. After a well-known air-conditioning brand installed this series of fans, the product noise complaint rate dropped by 70%, and user satisfaction increased to 96%.

Whether it is the severe test of industrial scenarios or the detailed demands of the home appliance field, Blauberg axial fans and tangential blowers have achieved the leap from "scenario adaptation" to "scenario leadership" through technological innovation. In the future, with the research and development of bionic impeller design, air flow efficiency will be further improved to provide better solutions for more segmented fields.
