The Wacker Neuson Fan is a genuine OEM component designed for the FU 4/200, FU 5z/200, FU 4/200 SW, FU 4/200 SW-S, and FU 4/250/200 SW-S internal concrete vibrator converter series. Sourced directly from Wacker Neuson, this fan carries the same part number and specification as the original fitted unit — ensuring a direct, confidence-assured replacement. It serves the full range of FU-series converters, making it the correct choice whether you are servicing a standard FU 4/200 or one of the SW-S converter variants. When your unit runs warm or the fan shows signs of wear, replacing it with part number restores proper thermal management and keeps your converter operating within its designed parameters.
Key Features
- Genuine OEM Specification — Manufactured to Wacker Neuson's exact blade geometry and motor-coupling dimensions, ensuring correct airflow output specific to FU-series converter cooling requirements.
- Direct Drop-In Replacement — Matches the original mounting configuration of the FU 4/200 and related converter models, so installation uses the same hardware and seating as the unit being replaced.
- Broad FU-Series Compatibility — Confirmed fitment across FU 4/200, FU 5z/200, FU 4/200 SW, FU 4/200 SW-S, and FU 4/250/200 SW-S converters, covering a wide range of internal vibration equipment.
- Sustained Converter Performance — A properly functioning fan maintains safe operating temperatures inside the converter; a worn or seized fan can lead to thermal shutdown or permanent damage to internal electrical components.
- Electrical Safety Relevance — Adequate cooling is critical in high-frequency converter units operating at 200 Hz and 42 V output; using the correct OEM fan preserves designed thermal clearances and protects downstream vibrator components.
The fan in a Wacker Neuson FU-series converter is responsible for drawing air across internal electrical components to dissipate heat generated during high-frequency power conversion. These converters step utility voltage down and increase frequency to drive internal concrete vibrators at the high speeds needed for effective concrete consolidation — a process that generates significant heat under sustained use. When the fan fails or degrades, heat builds up inside the enclosure, triggering thermal protection shutdowns or, in severe cases, causing lasting damage to the converter's electronic components and reducing the effectiveness of concrete vibration on the jobsite.
