Multi-blades Centrifugal Fan

The multi-blade centrifugal fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. According to the principle of converting kinetic energy into potential energy, a high-speed rotating impeller is used to accelerate the gas, then decelerate and change the flow direction to convert kinetic energy into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, changes to the radial direction as the gas flows through the impeller, and then enters the diffuser. In a diffuser, the gas changes the direction of flow causing a deceleration, which converts kinetic energy into pressure energy. The pressure increase occurs mainly in the impeller, and secondly in the diffusion process. In a multi-stage centrifugal fan, a recirculator is used to move the airflow to the next impeller, creating a higher pressure.

The multi-blade centrifugal fan is a forward, multi-blade, narrow-wheel impeller with excellent process design, solid material, reliable performance, low noise, high efficiency, long life, small volume, high pressure, and easy installation. This series of fans are widely used in telecommunications, electricity, electronics, coal mines, ships, papermaking and other industries, especially for plastic machinery, printing machinery, cable machinery, blow molding machines, printers, dryers, cooling and temperature control of underground facilities and ventilation.
