Continental Fan's DC Motorized Centrifugal 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 a DC external rotor motor, new standards for air performance and sound levels have been achieved. 
DC Impellers are completely speed controllable. Motor and impeller are located directly in the air stream, providing excellent heat dissipation and efficient motor cooling.   
Suitable for either supply or exhaust use, DC Impellers are an excellent choice for applications where transient electrical noise is prohibited.
