All in One Wastewater Aeration Blower for Chemical Powder Handling Plant
Product Introduction
Our blower incorporates three critical components. First is the ternary flow impeller made of 7075 aluminum alloy, enabling stable ultra-high speed operation. Precision-machined using five-axis CNC technology and designed with ternary flow principles, it achieves 92% multi-variable efficiency. Second is the high-efficiency permanent magnet motor featuring advanced air-cooling technology (97% efficiency), with characteristics including variable frequency speed control, energy efficiency, compact structure, high power density, wide speed range, strong overload capacity, and excellent reliability. Third is the self-acting hydrodynamic air bearing with flexible surface support, offering exceptional durability, reliability, stability, load capacity, and heat resistance. This lubrication-free design minimizes power loss, eliminates internal friction (rotor vibration <0.02mm), and has passed 20,000 start-stop cycles, making it virtually a permanent bearing solution.
