Axial Fans

Blaunerg Axial fans adopt both metal welding and single-piece plastic with glass fiber reinforcement aerodynamic impeller, compact energy-saving smart EC motor drives it with maintenance free ball bearing to guarantee longer lifespan. The fans could be installed at all directions with variety of fan safety guard grill, wall ring and air-guiding wind deflector dome where the patten and causation of flow loss caused by the pressure distortion in rotor and stator were analyzed. Quieter sound level contributes at customer requested fan performance working point compare with competitors in their ventilation, heating, refrigeration product or system. AC and DC power supply are available for entire range of fans with integrated and intelligence EC technology motor with inside or outside mounted international standard remote control R485 communication protocol that’s suitable to be adopted in IoE(Internet of Everything), IoT(Internet of Things), smart home system, Industry 4.0 and committed to Carbon Neutrality climate change by reducing customers carbon footprints. PFC(Power Factor Correction), up to λ>96%, is optional for electricity grad stabilization compliance in certain circumstances of applications.
