Wacker Neuson 5000152885 Rear Duct Left Side Insulator

The Wacker Neuson Rear Duct Left Side Insulator is a genuine OEM component designed for the G50, G70, and G85 series skid-mounted and mobile generators. Sourced directly from Wacker Neuson, this insulator is manufactured to the same standards as the part originally installed on your machine. Fitment covers skid-mounted and cold-weather mobile generator configurations across the G50, G70, and G85 series, making this the correct choice for operators running any of these units in demanding field conditions.

Key Features

• Genuine OEM Thermal Integrity — Manufactured by Wacker Neuson to maintain the correct thermal barrier rating of the original rear duct assembly, preventing heat transfer and protecting surrounding components.
• Left-Side Specific Fit — Engineered exclusively for the left-side rear duct position; installs directly into the existing mounting points without rework or shimming.
• Broad G-Series Compatibility — Fits G50, G70, and G85 skid-mounted mobile generators, including standard and cold-weather configurations, across multiple machine numbers.
• Protects Airflow Path Performance — A correctly seated duct insulator keeps exhaust and cooling air channeled as designed; a damaged or missing insulator allows heat to migrate into unintended areas, accelerating wear on adjacent parts.
• Thermal and Electrical Safety Relevance — Proper insulation in the rear duct zone is critical to maintaining safe surface temperatures and protecting wiring and fuel system components routed near the exhaust path.

The rear duct left side insulator forms part of the thermal management system within the generator enclosure. Its role is to line and seal the left-side panel of the rear duct, directing hot exhaust airflow out of the machine while shielding the surrounding structure from excessive heat buildup. When this insulator degrades, cracks, or goes missing, heat can radiate into adjacent compartments, putting wiring, hoses, and structural panels at risk and potentially triggering thermal protection shutdowns. Keeping this component in sound condition is essential to the safe, continuous operation of the G50, G70, and G85 generator units.
