What is the difference between high-voltage blower and blowe

Fans have high-voltage blower and low-voltage blower. High-pressure fan generally has high speed, small blade, large blade angle and small handling air volume compared with low-pressure fan (fan blade length is short, fan diameter is small, blade speed is more than 1500 revolutions/minutes close to 45 degrees angle full pressure can reach more than 800Pa). Low-pressure fan generally has low speed, low wind pressure and large handling air volume (fan blade). Length of sheet, large diameter of fan, low speed about 500 rpm/min 50Par) Low-pressure fan generally has a larger air handling capacity, suitable for places where large volume of mute displacement air is needed.
Fan is a kind of driven fluid machinery, which relies on the mechanical energy input to increase the gas pressure and discharge the gas side by side. Fan is the customary abbreviation of gas compression and gas conveying machinery in China. Generally speaking, fans include fans, blowers and wind turbines.
Gas compression and gas conveying machinery is a machine that converts rotating mechanical energy into gas pressure energy and kinetic energy and conveys gas out.
The main structural components of the fan are impeller, casing, air intake, bracket, motor, belt pulley, coupling, muffler, transmission parts (bearings), etc.
Non-power ventilator is the use of natural wind and indoor and outdoor temperature difference caused by the air thermal convection, to promote the rotation of the turbine, so as to use centrifugal force and negative pressure effect to discharge indoor stale hot air.
