Component display

Blades are made from Krupp self-cleaning stainless steel through a stamping forming process that is beautiful in appearance and prevents dust accumulation. Specially enhanced fan-shape design allows for large and constant air volume, no deformation or breakage. The thickness is 1.2mm and the surface finish reaches BA grade.

The belt pulleys are all made from high-strength aluminum-magnesium alloy through a die casting process that enables excellent corrosion resistance and lightweight performance. Special pulley design with three reinforced ribs, in combination with blast sanding surface treatment enhance the aesthetic extent and eliminate internal stress to effectively improve its own strength that it is not easily broken.

Both YUYUN SANHE motor and SIEMENS motor are available, with voltage and frequency customizable depending upon customers' needs. Motor protection level IP55, insulation grade F.
