Axial fan blades are currently domestically used variable-section space-distorted airfoil blade technology, which has a long service life, is not easy to cut, and has high efficiency conversion, which effectively reduces the noise of the blade rotation.

The axial fan wheel shell adopts the channelless wind to clamp type technology, which can reduce the installation space and make the installation more convenient. The installation angle can be adjusted according to the user's demand for air volume and pressure. The fan blades are positioned by the clamp type wheel shell to increase the blade Strength, operation is more stable.

The blades of the axial flow fan can be adjusted to make the blades produce forward flow and realize the need of forward ventilation, and it can also be adjusted to make the blades produce reverse flow and realize the need of reverse ventilation. The installation angle of the blades is 15-40 six kinds. Do static stepless adjustment.
