Elta impellers are ruggedly constructed, says the company, with cast aluminum hubs and steel taperlock bushings. Airfoil shaped, adjustable-pitch blades are available in pressure-cast aluminum or glass-reinforced polypropylene (GRP). Both materials and both rotations are stocked for quick response, the manufacturer says. The company’s fan selection software program allows users to choose from a wide range of possibilities and select the impeller that best meets their application criteria, the company says.
