Equipped with a powerful copper motor and high-precision bearings for effective rotor rotation. Ensures smooth operation, time savings, improved work efficiency, and reduced environmental pollution.Discover enhanced performance with our regenerative fan, engineered for both powerful blowing and suction functions. Made from a sturdy aviation aluminum shell, this fan is fireproof, resistant to high temperatures, and designed for superior heat dissipation. It features a robust copper core motor and a double-sided all-aluminum impeller, maximizing efficient centrifugal circulation to deliver optimal air discharge with reduced vibration, ultimately boosting work efficiency. Key features include: 1. Durable Material: The fan is constructed from a single-piece aviation aluminum shell and a double-sided all-aluminum impeller, providing exceptional fire resistance, high-temperature tolerance, and effective heat dissipation. 2. High Power: It is powered by an efficient copper core motor with fully sealed steel bearings, facilitating smooth centrifugal air circulation, ensuring high wind pressure and quick wind speed. 3. Thoughtful Design: The dual-purpose functionality for blowing and suction is enhanced by an integrated air duct silencer sponge and dust filters at both the inlet and outlet.
