Weg IEC Tru-Metric Totally Enclosed Fan Cooled Motors are designed and built according to European IEC 34 and IEC 79 Standards. The enclosure TEFC (IP55) is ideal for indoor and outdoor applications. These motors are tested according to IEEE 112 std., method 'B' and their efficiency values are certified according to EPACT regulations (CC029A).
Weg W22 motors are tough enough for severe duty applications. The sturdy cast iron body is covered with durable epoxy paint, and the gasketed conduit box prevents contaminants from getting in. More motor features include:
- Optimized cooling system
- Inverter Duty
- Movable conduit box
- Bearing seal system
- Low Vibration levels
- 1.25 S.F.
- Certified Class 1 Div 2, Groups A, B, C, D; Class II, Div 2, Groups F&G
