Q2: What is the energy efficiency performance of the fan, and why can it achieve high efficiency and energy saving?
A2: The fan has excellent energy efficiency performance, and the core reason lies in the dual optimization design: first, the composite material impeller is optimized by ternary flow CFD fluid simulation technology, combined with a reasonably designed flow channel to reduce air flow loss; second, it is equipped with an ultra-efficient EC motor, which itself has low energy consumption and high conversion efficiency. The combination of the two realizes the overall high efficiency and energy saving of the fan, suitable for various energy-sensitive scenarios.
Q3: What is the noise control level of the fan, and can it adapt to scenarios with high silent requirements?
A3: The fan has excellent low-noise performance. The design team deeply combines aerodynamics with sound source characteristics, making the blade angle and blade pattern fully adapt to the ternary flow field, which can continuously maintain lower noise at the same air volume, and can adapt to scenarios with high silent requirements such as IDC small cabinets and commercial air conditioners.
Q4: What guarantees are there for the reliability of the fan, and can it adapt to harsh environments?
A4: The fan has multiple guarantees for reliability: the motor has IP54 waterproof and dust-proof protection level and F-class insulation, which can resist the invasion of dust and water vapor; at the same time, it has passed 3 months of continuous 60℃ high temperature test and 40,000 hours of life test, with stable and worry-free quality; anti-vibration structure design is adopted for some scenarios (such as rail transit), which can adapt to harsh environments such as vibration and variable temperature and humidity.
