The Wacker Neuson 15.75 Fan is a genuine OEM cooling fan designed for the G25 and G20 series mobile generators, covering skid-mounted, custom, cold weather, extended run, and Tier 4i/4F configurations. As a direct OEM replacement, this fan is manufactured to the same specifications as the original, ensuring proper airflow across the generator's cooling system. It is compatible across a broad range of G25 machine numbers and select G20 variants, making it the correct choice for most G25 fleet configurations.
Key Features
- Correct Blade Diameter: — At 15.75 inches, this fan matches the original swept area specification, delivering the airflow volume the G25 and G20 cooling systems depend on.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, this fan is manufactured to the same tolerances and material grade as the unit installed at the factory.
- Broad G25 and G20 Compatibility: — Fits skid-mounted, custom, cold weather, extended run tank, and Tier 4i/4F G25 configurations, as well as select G20 mobile generator units.
- Drop-In Replacement: — Designed to mount using the existing hardware and hub interface, allowing a straightforward swap without machining or adapter components.
- Prevents Thermal Overload: — A worn or damaged fan reduces airflow to the engine and alternator, leading to elevated operating temperatures that accelerate wear and can trigger automatic shutdowns on the jobsite.
The cooling fan on a portable generator draws or pushes air across the engine and alternator to dissipate heat generated during continuous power production. Without adequate airflow, internal temperatures rise beyond safe operating limits, stressing engine components and shortening alternator life. On G25 and G20 series generators — which are commonly run at sustained load for extended periods on construction sites — a correctly sized and properly balanced fan is critical to maintaining stable output and protecting the drive system from heat-related damage.
