The Wacker Neuson Rear Air Inlet Duct Xlg is a genuine OEM component designed for the G150, G180, G230, and G240 series portable generators. Sourced directly from Wacker Neuson, this duct is manufactured to the exact dimensions and material specifications of the original part, ensuring a correct, trouble-free installation. It is compatible across a wide range of G-series generator configurations, including standard, cold weather, custom, and multi-voltage variants spanning Tier 3, Tier 4, and Tier 4 Final emissions levels.
Key Features
- OEM-Grade Airflow Integrity — Formed to the precise profile of the original duct, maintaining correct air volume and velocity through the generator's cooling system.
- Drop-In Replacement — Matches original mounting points and duct geometry on G150, G180, G230, and G240 generator enclosures for a straightforward swap.
- Broad G-Series Compatibility — Verified fitment across multiple G150, G180, G230, and G240 configurations, including standard, cold weather, custom, and Transport Canada spec units.
- Cooling System Performance — A correctly fitted inlet duct ensures the engine and alternator receive adequate airflow, preventing thermal stress that can shorten service life or trigger shutdowns under load.
- Durable Construction — Built to withstand the vibration, temperature cycling, and outdoor exposure typical of mobile generator operation on active job sites.
The rear air inlet duct channels outside air into the generator enclosure to cool the engine and alternator during operation. Without a properly sealed and correctly shaped inlet duct, airflow through the enclosure becomes turbulent or restricted, causing heat to build up around critical components. A cracked, warped, or missing duct can lead to overheating, nuisance shutdowns, or accelerated wear on the engine and alternator — particularly during sustained high-load operation. Replacing a damaged duct with a genuine OEM part restores the designed airflow path and keeps the generator running within its intended thermal limits.
