Wacker Neuson 5000152905 Rear Side Duct Insulator

The Wacker Neuson is a genuine OEM Rear Side Duct Insulator designed for G120, G125, and G160 series mobile generators. Sourced directly from Wacker Neuson, this insulator matches the exact material grade and dimensional profile of the original component installed at the factory. It is confirmed to fit skid-mounted, custom, and cold-weather configurations across the G120, G125, and G160 generator families, covering a broad range of jobsite power applications. When your original insulator is damaged or worn, replacing it with the correct OEM part keeps heat routed properly and protects surrounding components from thermal stress.

Key Features

• Genuine OEM Thermal Material: — Manufactured to the same insulation grade as the original, ensuring consistent heat resistance and duct sealing performance specific to this generator enclosure design.
• Drop-In Replacement: — Matches the original mounting points and duct geometry of the G120, G125, and G160 enclosure so installation is straightforward with standard hand tools.
• Broad G-Series Fitment: — Compatible with skid-mounted, custom, and cold-weather variants of the G120, G125, and G160 mobile generator lines, covering multiple configuration types within a single part number.
• Protects Adjacent Components: — A properly functioning duct insulator contains exhaust heat within the designed airflow path, preventing heat soak to wiring, fuel lines, and enclosure panels that can lead to premature wear or damage.
• Verified OEM Part Number: — Part number 5000152905 is the factory-correct reference for this application, eliminating guesswork when cross-referencing against your machine's serial number and configuration.

The rear side duct insulator lines the exhaust or ventilation duct channel at the rear of the generator enclosure, containing heat within the designed airflow path and preventing it from radiating into surrounding structural and electrical components. Without an intact insulator, excessive heat can migrate to areas of the enclosure not built to withstand it, degrading wiring insulation, seals, and painted surfaces over time. On cold-weather-configured units in particular, maintaining correct thermal boundaries is essential to keeping the machine operating within its designed temperature range.
