The Wacker Neuson Duct is a genuine OEM component designed for the HI 770 XHD series indirect-fired diesel air heaters, including Arctic Bear XHD and HI770XHD configurations. As a factory-sourced part, the matches the original specification for correct airflow routing and a secure, leak-free fit within the heater assembly. This duct is compatible across multiple HI 770 XHD variants, covering 1x16, 1x20, and 2x12 duct configurations as well as Extra Heavy Duty Air Heater builds. When your existing duct is cracked, collapsed, or deteriorated, replacing it with the correct Wacker Neuson part restores full heating output and keeps your crew working through cold-weather conditions.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional spec, ensuring the duct maintains its shape and integrity under sustained high-temperature airflow.
- Direct-Fit Replacement — Engineered to connect at the same attachment points as the original, so installation on HI 770 XHD units is straightforward with no reworking of surrounding components.
- Broad HI 770 XHD Compatibility — Fits Arctic Bear XHD, Arctic Bear XHD NS, and HI770XHD series heaters across multiple machine configurations, including 1x16, 1x20, and 2x12 variants.
- Uninterrupted Heat Delivery — A properly seated duct channels heated air efficiently to where it's needed; a cracked or ill-fitting duct bleeds heat, reduces output, and forces the heater to work harder in freezing conditions.
- Verified OEM Part Number — Ordering by part number 5000169719 confirms you're receiving the exact component Wacker Neuson specifies for these HI 770 XHD heater assemblies, eliminating guesswork on compatibility.
The duct in an indirect-fired air heater is the channel that routes the warmed air output from the heat exchanger to the discharge point or connected hose runs. It keeps the heated airstream contained and directed, which is essential for efficient heating performance across a worksite or enclosed space. When a duct cracks, collapses, or pulls loose from its connection points, warm air escapes before it reaches its destination — reducing effective output and placing extra load on the burner system. Replacing a damaged duct promptly with the correct OEM part restores full airflow efficiency and protects the broader heating system from strain.
