The Wacker Neuson 24" Fan is a genuine OEM component designed for the G70 and G100 series portable generators. As a direct OEM replacement, this fan is produced to the exact specifications required by Wacker Neuson, ensuring it seats and spins correctly within the generator's cooling system without any fitment guesswork. The covers an extensive range of G70 and G100 configurations, including Standard, Cold Weather, Custom, and Extended Run variants across T4, T4i, and T4F emission tiers. When your cooling fan is cracked, broken, or out of balance, replacing it promptly with the correct OEM part protects the engine from heat-related damage and keeps your generator producing full rated output.
Key Features
- OEM-Matched Blade Geometry — Manufactured to the exact pitch, diameter, and balance spec of the original fan, delivering the correct cubic feet per minute of airflow the G70 and G100 cooling systems require.
- Direct Bolt-On Replacement — Engineered to match the original hub bore and mounting configuration, so installation goes straight onto the existing shaft without modification.
- Broad G70 and G100 Coverage — A single part number covers Standard, Cold Weather, Custom, Extended Run, and URI HVAC configurations across T4, T4i, and T4F emission tiers in both the G70 and G100 generator families.
- Protects Engine Temperature Under Load — A functioning fan draws cooling air consistently across the engine and alternator; a failed or cracked fan leads to thermal buildup that can force the generator into protective shutdown on the job.
- Genuine Wacker Neuson OEM Part — Sourced directly through the authorized Wacker Neuson parts channel, so you receive the same component installed at the factory — not an approximation.
The cooling fan on a portable generator is responsible for drawing a continuous stream of air across the engine and generating components to dissipate heat produced during operation. On the Wacker Neuson G70 and G100, the fan works in concert with the engine shrouding to direct airflow precisely where cooling is needed most. When the fan cracks, chips, or loses a blade, airflow drops and the balance of the rotating assembly is disrupted — both conditions accelerate wear on bearings and can trigger high-temperature shutdowns. Replacing a damaged fan with the correct OEM part restores proper thermal management and keeps the generator running at full capacity through extended runtimes.
