the main features and selling points of the fan
(1)the overall structure of the fan hydrodynamic design ability of wind pressure, negative pressure output stability;
(2)machine flue gas is lower than the same industry products 20% (ppm) thermal efficiency can improve by 2-3 percentage points;
(3)the motor configuration hall sensor output voltage controller with control points in order to achieve different air pressure machine
(4)the motor can be run at low voltage (187v) to ensure that the wind turbine output voltage fluctuation factors negative pressure can be maintained for the machine to work properly;
(5)solder joint welding firm and strong tensile strength of up to 6000-7000n;
(6)low fan noise (≤ 60db) using reliable long life;
