The SDS and SDS(R) are designed by Shanxi Jinyun Anfeng Machinery Co., Ltd. for tunnel ventilation systems. The fan uses a direct-drive motor, and the blades are cast aluminum alloy airfoil blades. According to the actual application scenarios, it is divided into two series: SDS unidirectional jet fan and SDS(R) reversible jet fan. The blades of both fans are adjustable.

Standard jet fans can be selected according to Jinyuan's product catalog. Jinyuan can also customize designs to meet specific thrust requirements by modifying the fan hub diameter, number of blades, and blade angle.

The components of this type of fan are: fan section (including casing, motor/motor bracket, impeller), external junction box on the casing, inlet and outlet silencers, protective net cover and bell-shaped mouth. For special noise requirements, a silencer core can also be used. When installing the jet fan, the support position should be on the fan section, not the silencer section. The silencer is connected to the fan using a flange. Typically, the length of the silencer is 1 or 2 times the diameter of the fan, depending on the technical requirements. For vibration isolators, different types and materials of vibration isolators are available depending on the application and technical requirements. They have advantages such as low natural frequency, wide applicable load range, simple structure, and easy installation.
