Fan-Motors
- EC fan motors
- Available with high efficiency axial EC fans Ø 914 mm, in a range of different fan speed executions, 1 to 14 fans.
- Motors with external rotor, protection class IP55, F-class insulation.
- Corrosion resistant fan blades and guards.
- IEC fan motors
- Direct driven axial fans with squirrel-caged motors for outdoor use built to IEC standards.
- Ø 910 or 1240 mm.
