1. Spiral Inlet Design: The fan inlet employs a spiral configuration, creating sequential cavities that open and close with impeller rotation, effectively minimizing fan pulsation.
2. Advanced Rotor Technology: Enhanced rotor design with a utilization coefficient of 0.53 boosts volumetric efficiency by 5%~8% at 98kPa pressure, while reducing noise by approximately 5dB(A).
3. Precision Manufacturing: All rotors are crafted using precision CNC equipment and inspected by a three-coordinate measuring center, ensuring uniform performance across turbines. Dynamic and static balance tests are conducted pre-assembly, resulting in minimal fan vibration.
4. High-Precision Grinding Gears: Utilization of high-precision grinding gears reduces mechanical noise to meet Grade 5 precision standards set by national standard GB/T 10095-2008.
5. Enclosed Oil Tank and Lubrication System: A fully enclosed oil tank and lubrication system prevent oil spraying and leakage, eliminating on-site pollution common with older Roots fan models.
6. Echo Corridor Structure: Developed in collaboration with a Beijing acoustics research institute, the "echo corridor" structure dissipates heat from lubricating oil while effectively reducing mechanical noise by about 3-5dB(A).
7. Enhanced Parts Interchangeability: Improved quality and production management systems enable the interchangeability of various fan parts, reducing production costs and lead times. Ample inventory ensures same-day delivery for prompt service.
