High Aerodynamic Efficiency: Features twisted airfoil blades with C4-II ternary flow wing design for significant energy saving.
Stable Operation Safety: Equipped with steady flow ring device; characteristic curve has no hump to prevent surge risk.
Durable Blade Material: Blades use wear-resistant anti-corrosion metal coating, 10 to 50 times more durable than carbon steel.
Flexible Wind Reversal: Capable of reversing wind with a rate greater than 60%, eliminating need for reverse wind channels.
Adjustable Blade Angle: Blade installation angle is adjustable to adapt to changing mine working conditions anytime.
Compact and Moisture Resistant: Steel plate and section steel block welding structure ensures high strength and moisture resistance.
Direct Drive Structure: Motor and impeller direct connection offers high stability, low resistance, and easy maintenance.
Wide Application Range: Suitable for coal mines, metallurgy, tunnels, civil air defense, and large workshops.
