We offer axial fan impellers made by Wentech/PL, Howden/NL, Cofimco/I, and other manufacturers.
Fan selection criterias are maximum efficiencies and adequate flow and pressure margins. The low-weight airfoil aluminum and fiberglass reinforced polyester fan blades are statically balanced for smooth and trouble-free operation. The blades are connected with the epoxy coated or galvanized steel hub plates by means of aluminum brackets and stainless steel bolting.
Fan impellers are available in a large variety of sizes, materials and cost ranges and, of course, super silent designs.
