Continental Fan says its newest Elta axial impellers incorporate an advanced airfoil blade design that is both quiet and efficient. The impellers are designed with the latest computer aided technology, and integrates pressure cast aluminum hubs and adjustable pitch blades. Custom diameters are available from 12 inches to 79 inches, and deliver airflows to 200,000 cubic feet per minute. Elta impellers are ideal for manufacturer applications or as replacement impellers, officials say.
