The TNK Motorized Impeller is designed for applications where space is limited. The fan combines the efficiency of the TEK backward-curved airfoil wheel with the technology of an external rotor motor. According to the company, this achieves better air performance and sound levels. The fan is suitable for either supply or exhaust applications, and includes a 100 percent speed-controllable external rotor motor. Models are available in one- or three-phase voltages and 500 cfm and 5,000 cfm.
