The Wacker Neuson Air Duct is a genuine OEM component designed for the G70, G95, G100, and G120 series portable generators. As a direct OEM replacement, this air duct is manufactured to the same specifications as the original part, ensuring a correct fit across the full range of G-series generator configurations — including standard, cold weather, skid-mounted, Tier 4i, Tier 3, and custom variants. Whether you're servicing a mobile unit on a job site or maintaining a permanent skid installation, part number restores proper airflow management to your generator. Confirm your model number against the fitment list before ordering to ensure compatibility with your specific configuration.
Key Features
- Genuine OEM Airflow Geometry — Manufactured to the exact duct profile and dimensions of the original, so air is directed correctly through the generator enclosure without gaps or misrouting.
- Drop-In Installation — Mounts to the same attachment points as the factory part across all G-series configurations, with no trimming or adaptation needed.
- Broad G-Series Compatibility — Fits G70, G95, G100, and G120 generator models across standard, cold weather, skid-mounted, Tier 3, Tier 4i, and custom configurations.
- Sustained Cooling Performance — A correctly seated air duct maintains the designed airflow path through the generator set; a cracked or missing duct allows hot air recirculation, which can cause the engine to run hot and trigger thermal shutdowns.
- Thermal Safety Compliance — Proper air ducting is critical to keeping engine and alternator temperatures within safe operating limits, protecting both the machine and the electrical loads it serves.
The air duct channels cooling air from the intake through the generator enclosure and across the engine and alternator, then directs spent hot air out of the housing. This controlled airflow path prevents heat buildup that can degrade insulation, shorten alternator life, and cause the engine to overheat. When an air duct cracks, warps, or comes loose, hot exhaust air can recirculate back through the intake, steadily raising internal temperatures until the generator's thermal protection system shuts the unit down — or, in severe cases, causes undetected heat damage to electrical components.
