Shangyu Shanggu Pipe Ventilation Fan Low Noise Mixed Pressure Flow Fan

Shangyu Shanggu Pipe Ventilation Fan Low Noise Mixed Pressure Flow Fan Installation and Usage
Horizontal, vertical, and suspended ceilings can be installed. Exhaust, supply, and pipeline pressurization can all be used. Fan usage, maintenance, and upkeep

SWF low-noise mixed flow fan manufacturer quotation for maintenance and upkeep
1. Before installation, carefully check whether the fan blades and casing are damaged or deformed due to transportation, otherwise they should be repaired before installation;

2. Check if the blades and air ducts have collided with the shell due to loose connecting screws. If the gap between the blades and air ducts is uneven, it should be adjusted before installation;

3. Before starting the fan, the first thing to check is whether there are any objects inside the fan and pipeline that hinder rotation;
4. Check whether the insulation performance of the motor is good, and after connecting the power, check for friction, collision, and abnormal vibration;

5. During normal operation, if the motor temperature rises above 70 degrees Celsius, it should be stopped immediately for inspection; Electric Changbai Smoke; Strong vibration or loud magnetic noise occurs.

1. The fan mechanism is compact, easy to install, and reliable to operate: This fan has a smaller volume than axial flow fans under the same air volume and pressure, and can be directly connected to the air duct. It can be installed horizontally or vertically, and is easy to operate and use
2. Low noise: The casing of this fan has been specially designed to significantly reduce external noise. Under the working conditions of unit air volume and unit air pressure, the sound level can be reduced by 2-3dB (A) compared to A, and at lower speeds, higher fan pressure can be obtained. In the air supply and exhaust systems of industrial and mining enterprises and high-end civil buildings, low-pressure centrifugal fans or high flow fans can be replaced without the need for extensive noise reduction measures.

3. Wide range of use: This series of products is available in two models: single speed and dual speed. The installation angle of the fan can be changed according to different usage scenarios, and the number of blades and speed can be adjusted to meet its requirements.

SWF (A) mixed flow fan is used in ventilation and air conditioning systems for situations where the fan volume is low and the air pressure is low

The newly developed fan, a mixed flow fan with a higher air volume than an axial flow fan and a lower air pressure than a centrifugal duct fan, combines the advantages of two different specifications to achieve an ideal state. Positive pressure air supply and negative pressure exhaust for ventilation ducts are both good choices. Based on the "quasi three element" theory and the "meridian acceleration" design method, we have successfully developed a new type of fan with a specific speed between centrifugal and axial flow, a pressure coefficient higher than that of an axial flow fan, and a flow system higher than that of a centrifugal fan. Therefore, the user selection range is wider, the system matching is more reasonable, which is conducive to energy saving and noise reduction of the system. It is currently the most suitable new product for pipeline pressurization systems in ventilation fans.

SWF low-noise mixed flow fan manufacturer quotationThe basic structural type is that the inlet and outlet are on the same axis (i.e. horizontal inlet and outlet), the impeller hub is a conical cylinder, and the blades have unequal width shapes along the flow direction. There are three types of cylindrical shapes: straight cylindrical, drum shaped, and imported with curved mufflers, which provide scientific basis for the full transmission of air volume and pressure. According to the principle of meridian acceleration of airflow, fans have dual characteristics of centrifugal and axial flow, with high pressure and large flow rate, as well as advantages such as high efficiency, low noise, and wide high-efficiency zone, which can effectively meet user requirements.
