This 120mm small double-inlet centrifugal blower adopts external rotor brushless motor, built in between the casing and the impeller. It is a driven fluid machine that relies on the input mechanical energy to improve the gas pressure and send the gas side by side. According to the principle of converting kinetic energy into potential energy, the gas is accelerated by high-speed rotating impeller, and then slowed down and changed the flow direction to convert kinetic energy into potential energy. Low noise, high work efficiency, large air volume, stable output performance, stable operation, energy saving and environmental protection, efficient loss reduction. The casing is made of high quality galvanized sheet, the volume of the fan is small, and the air inlet of the side plate is equipped with an air inlet ring, which can make the air flow into the impeller without loss of ground.
Volute design firm, compact structure, easy installation and use, light weight. Blades are designed to conform to specific aerodynamic shapes, resulting in higher efficiency, lower noise, lower vibration and greater stability. This double inlet centrifugal blower is widely used in large factory buildings, warehouses, stadiums, livestock farms, commercial places, high-rise buildings, residential buildings and so on.
