Key Features
- Genuine OEM Enclosure Integrity — Manufactured by Wacker Neuson to match the original guard geometry, ensuring proper airflow channeling and debris protection around the cooling fan assembly.
- Drop-In Installation — Mounts to the same factory attachment points as the original, with no trimming or drilling needed to fit the G100 or G120 generator housing.
- Broad G-Series Fitment — Confirmed for G100 and G120 T4i generators across Custom, Standard, Cold Weather, and Hertz configurations, covering the full production run of these models.
- Cooling System Protection — A properly fitted fan guard keeps foreign objects clear of the rotating fan blades, maintaining consistent airflow to prevent thermal buildup during extended generator operation.
- Personnel and Equipment Safety — Fan guards are a designated protective component; using the correct OEM replacement ensures the guard meets the original design intent for operator protection around exposed rotating parts.
The right fan guard shields the cooling fan on the generator's exhaust or intake side, directing airflow efficiently while preventing contact with rotating components. When a fan guard is cracked, missing, or improperly fitted, cooling performance can be compromised and rotating fan blades are left exposed — creating both a thermal risk to the engine and a physical hazard to anyone working near the unit. Replacing a damaged guard promptly with the correct OEM part restores safe, efficient operation and keeps the generator running within its designed thermal envelope.
