Shandong Yuyun Sanhe Machinery is a professional manufacturer of ventilation fans, industrial air heaters, cooling and humidifying equipment as well as light traps and filters. Our primary advantage lies in that each component used in our equipment is produced in our own factory, which allows us to control product quality and reduce production costs, enabling us to provide high cost-performance products.

Selection of raw materials
YUYUN SANHE purchases raw materials in a manner of large-batch centralized customization (General manufacturers use hot-dip galvanized steel plates with zinc coating thickness of 80g/m² for manufacturing, while we 275 g/m².), lowering production costs. The purchase prices are lower than market average while the products' quality higher than market quality.

Manufacturing workshop
Equipped with a complete set of numeric controlled manufacturing equipment and precision molds, all product parts are independently produced with an error range below 0.03mm. Our main processing equipment includes decoiler machines, fiber laser cutting machines, CNC shearing machines, CNC turret punch presses, electro-hydraulic synchronous numerical control bending machines, open type press with fixed beds, heavy-duty presses, open type presses, automatic welding machines, spraying lines, automatic hydraulic pipe benders, dynamic balance correcting machines for fan blades, high frequency seam welders, plastic injection molding machines, plastic extruders, automatic die-casting machines for aluminum and magnesium alloys, CNC lathes, etc.

Assembly workshop
YUYUN SANHE introduces high precision dynamic balance correcting machines for fan blades to perform dynamic balance testing and correction of each batch of delivered fan blades, preventing faults and noises caused by vibration that appears during fan operation. In addition to that, our company also imports advanced motor running detector to test motors at the power supply parameters of the country where the customer is located, so as to ensure the fans operate normally.
