Zhejiang Yidun Electromechanical Co., Ltd. (also known as Zhejiang Yidun Mechanical & Electrical Co., Ltd. or EDON/Redbo brand). It is the Vortex Blower Division section, focusing on vortex blowers (also called ring blowers, side channel blowers, regenerative blowers, or high-pressure vortex air pumps) and related accessories. These are commonly used for applications like pneumatic conveying, vacuum adsorption, water treatment aeration, printing, packaging, medical, and environmental uses.
Redbo Product Category & Specific Model (Inferred)
Welding Machine Category — Redbo WFJ Series
The page identifier “wfj_15” most likely corresponds to a product series within Redbo’s welding machine lineup. In typical Redbo naming conventions:
-
“WFJ” often appears as a welding machine product prefix (e.g., inverter welding machines)
-
The suffix “15” likely denotes a specific model within that series
This inferred product series typically belongs to inverter welding machines used for MMA / MIG / multi-process welding.
