Product Description
rrr fan overview
Series of low-noise mixed-flow fans are listed in the National Spark Plan The project is an energy-saving ventilation equipment jointly developed by Shanghai Jiao Tong University and promoted and produced by our company. In view of the current situation in the ventilation and air conditioning system where the fan pressure is too high but the flow is insufficient, or the flow is too high but the pressure is not enough, the system does not match the fan. Based on the quasi-ternary theory and the meridian acceleration design principle, we have successfully developed this system. This new type of fan has a specific speed between centrifugal and axial flow, a pressure coefficient higher than that of an axial flow fan, and a flow coefficient larger than that of a centrifugal fan. Therefore, the user selection range is wider and the system matching is more reasonable, so it is beneficial to System energy saving. Proven by a large number of practical applications, the majority of users agree that this product is the ideal energy-saving, environmentally friendly, simple and practical ventilation equipment.

Features of rrr fan
Compact structure, easy installation, reliable operation: The fan blade shape is designed through computer dynamic simulation, which can greatly reduce the vibration Noise, under the working conditions of unit air volume and unit wind pressure, the specific sound level can be reduced, and at the same time, at a lower speed, a higher fan pressure can be obtained. In the air supply and exhaust systems of industrial and mining enterprises and high-end civil buildings, it can replace low-pressure centrifugal fans or high-pressure axial fans without requiring a large number of noise reduction measures.

Fan model description
◆In order to meet different usage needs, we launch two types of products - type and - type. - type is a single-speed type, and - type is a two-speed type. Users can choose the appropriate model specifications according to their needs.
◆The performance parameters and external dimensions of the original type (high pressure type) have been incorporated into the original type.
◆The series of fans can also be made into special types such as silencer type, anti-corrosion type, explosion-proof type, roof type, etc. to adapt to different use occasions and conditions.
◆There are only five recommended working condition points. If the parameters selected by the user are not listed here, please contact the company's technical department and the company will provide curve selection.
