Available in single or 3-phase voltages, TMK Motorized AC Impeller is completely speed controllable. Impeller and dual frequency 50/60 Hz motor are located directly in airstream, where impeller acts as rotating heat sink with optimized heat dissipation and efficient motor cooling. Housed version TMK-H eases installation and minimizes assembly time. Both are equipped with BC airfoil wheel and provide capacities to 5,060 cfm. Matching capacitors and inlet cones are available.
