275g/m³ zinc coating is used for the galvanized sheet of the outer frame to effectively avoid rusting.
When the two doors of the fan are closed, a rubber sealing device is added. When the fans are not started at the same time according to the environment condition, the air backflow can be avoided effectively and the operating efficiency can be greatly improved.Compared with the same power fan, the efficiency can be increased by 15-20%.
Jianwei Fan's special fan shape design makes it self-cleaning to achieve the highest efficiency. The blades are made of Krupp self-cleaning stainless steel by die stamping, large air volume, no deformation, no fracture, no ash hanging, beautiful and durable.
stainless steel thickness: 1.5 mm
Surface finish: Ba
