W2D155-EB08-01 ebmpapst 400V 155mm IP55 AC Axial Fan

Description

The ebmpapst W2D155-EB08-01 is a professional-grade 3-phase AC axial fan designed for high-performance thermal management in demanding industrial environments. Featuring a robust 155 mm die-cast aluminum housing and a sickle-shaped sheet steel impeller, this unit is engineered for exceptional durability and vibration-free operation. A key technical feature is its dual-frequency compatibility, delivering a rated speed of 2600 RPM at 400 VAC (50 Hz) and reaching up to 3255 RPM at 480 VAC (60 Hz). With an upgraded IP55 protection rating, the W2D155-EB08-01 is fully protected against dust ingress and low-pressure water jets, making it ideal for cooling frequency converters and telecommunications cabinets in harsh conditions. Powered by an external rotor motor with integrated thermal protection, it ensures reliable S1 continuous operation and consistent air displacement across a wide temperature range of -25 °C to +75 °C.
