Continental Fan’s EC & DC Backward Curved Motorized Impellers are superbly crafted and precision balanced air-moving devices, featuring superior performance and compact design. By combining the efficiency of a backward curved airfoil wheel with the advanced technology of an EC or DC external rotor motor, new standards for energy savings and performance have been achieved.
EC Impellers are ideally suited for many air-moving applications, including cooling of motor controls, Electronic cabinet cooling, electronics, power converter cabinets, EC Fan array, and modular air conditioners.
DC impellers are completely speed controllable. Suitable for either supply or exhaust use, DC Impellers are an excellent choice for applications where transient electrical noise is prohibited.
