About Structure
The blades are designed with high-efficiency and low-noise wing shapes, and both the hub and blades are made of high-quality high-strength aluminum alloy by die-casting.
Treatment onto Blade
Each blade has been done by heat treatment, X-ray inspection, tensile testing, and approved by metal performant test, dynamic balance verification which ensures reliable quality for safe operation.
About Dual Dynamic Balancing Test
The dynamic balancing of the whole impeller is introduced in the link of SDS jet fan.
Adjust Blade Angle to Fit Your Working Condition
The blade angle is adjustable and stationary. After stopping the machine, loosen the blade bolt and adjust the blade angle to adapt the flow rate and pressure of the fan to meet different operating conditions.
Switch Forward to Reverse Rotation
The switchable rotation of the whole impeller is introduced in the link of SDS jet fan.
