Product description
Structure
4-72 centrifugal fan is an efficient and energy-saving centrifugal fan. Its structure, such as airfoil-shaped blade, curvilinear impeller front plate and conical and arc inlet collector, gives the fan excellent aerodynamic performance. It has made a great contribution to our economic construction. The fan can be driven in four ways: A, B, C and D. Type A is the direct drive between impeller and motor. Type B is belt drive with belt pulley between two bearings; Type C is belt drive with the belt pulley on the cantilever outside the bearing; Type D is driven by impeller and motor through coupler.
Applicable occasion
