Supply of circular duct ventilation fan

Supply of circular duct ventilation fanprinciple

The circular duct fan adopts a wing shaped backward tilting impeller, which fully utilizes the gas fluid dynamics during high-speed operation, resulting in a very high energy efficiency ratio of up to 70%. This means that a small motor power can deliver large wind power, which is an effect that ordinary forward tilting centrifugal fans cannot achieve. Therefore, pipeline fans are both energy-efficient and capable of producing strong winds. The ultra-high wind pressure can be connected to a pipeline of tens of meters for centralized ventilation, and the main characteristic of the pipeline fan is high pressure. Replaced traditional ventilation equipment. The fan has no vibration and a dynamic balance value of less than 0.17g. Only such a standard value can ensure the quality of the fan. The imported metal impeller is matched or PP plastic is poured according to the wing shape. Its characteristics are strong rigidity, high temperature resistance, environmental protection, large air volume, and can reduce noise to a certain extent.

Duct ventilation fans are generally divided into circular duct fans and square duct fans.

The casing of a circular duct fan is cylindrical, which is an ideal ventilator that combines performance and appearance; It has the characteristics of easy installation, light weight, and low noise. The shell of a square duct fan is square, and its internal structure is similar to a circle.

Supply of circular duct ventilation fanIt is a circular pipeline centrifugal fan. Its straight in and straight out design greatly facilitates the workload of installing and connecting pipes. The impeller of the fan is designed with an aluminum wing shaped high-efficiency blade shape, which provides high air volume and high static pressure performance while ensuring low noise levels. The flange of the air inlet and outlet is a standard configuration, and the design of this fan makes it suitable for lifting or floor installation. Its impeller width can be designed to achieve the required air volume and pressure under direct connected constant speed conditions. Avoiding the need for a frequency converter to adjust the speed to achieve the desired parameters in the responsible system, thereby reducing initial investment.
