AC Snail Centrifugal Blower Fan is a kind of driven fluid machine which relies on the mechanical energy input to increase the gas pressure and to discharge the gas side by side.Centrifugal fans are widely used for ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings.Ventilation and induction of boilers and industrial kilns;Cooling and ventilation in air-conditioning and household appliances;Drying and selection of grains;The wind source in the wind tunnel and the charging and pushing of the hovercraft.

AC Snail Centrifugal Blower Fan uses a high-speed rotating impeller to accelerate the gas according to the principle of converting kinetic energy to potential energy, then decelerates and changes the flow direction to convert kinetic energy to potential energy (pressure).In single-stage AC Snail Centrifugal Blower Fan, gas enters the impeller axially, and as it passes through the impeller, it changes to a radial direction, then enters the diffuser.In the diffuser, the flow direction of the gas is changed and the airflow is decelerated by an increase in the cross-section area of the pipe. This deceleration converts kinetic energy into pressure energy.The pressure increase mainly occurs in the impeller, followed by the diffusing process.In the multi-stage AC Snail Centrifugal Blower Fan, a return current is used to flow the air into the next impeller, generating higher pressure.

AC Snail Centrifugal Blower Fan works essentially the same as a turbine compressor because the gas flow rate is low and the pressure does not change much. It is generally not necessary to consider the change of the specific capacity of the gas, that is, to treat the gas as an incompressible fluid.

AC Snail Centrifugal Blower Fan can be made into right-hand and left-hand styles.Look directly at the side of the motor: the impeller rotates clockwise, called the right rotating fan;The impeller rotates counterclockwise, called the left rotating fan.
