Plastic Hub With Plastic Blades
Description: Axial impellers utilise blades with an airfoil profile with plastic/aluminium hubs having optional mounting arrangements for a wide range of HVAC&R applications for air conditioning, refrigeration, air curtain, clean room equipment, cooling tower, ventilation and air washers. This profile is chosen for a wide range of applications including HVAC, compressor and engine-driven equipment. The blade dimension is chosen to provide a uniform blade area resulting in optimum performance advantages. The impellers are common one-piece injection moulded. The impeller diameters range from 315 to 810 mm with pitch angels from 15° to 40° to meet specific application requirements. The blades are fixed in the hub by means of a plastic angle locator, ensuring a preset blade angle that can not move or change under load. The blades are made from high strength injection moulded thermal plastics. These find applications in air conditioning plants, ceramics industry, condensers, construction machines, cooling installations, dry cooling towers, earth movers, gearboxes, generator sets, harvesting machines, hot air generators, hovercraft, internal combustion engines, industrial plant, municipal service vehicles, plant protections installations, ventilating fans, vehicles and transformers.
