The Wacker Neuson Flange is a genuine OEM component designed for HI 400HD D and HI 120HD indirect-fired air heaters. As a factory-sourced part, it is manufactured to the exact specifications required by Wacker Neuson, ensuring a correct, consistent fit within the heater assembly. This flange is the right choice when restoring your HI-series heater to full operating condition and you need a part you can trust to match the original.
Key Features
- Factory-Matched Tolerances — Manufactured to OEM dimensional specs, so mating surfaces seal and align exactly as designed for heater duct and burner assemblies.
- Direct OEM Replacement — Sourced directly from Wacker Neuson; installs in place of the original flange without alteration or adaptation.
- HI-Series Heater Compatibility — Confirmed fitment for the HI 400HD D and HI 120HD indirect-fired air heaters.
- Combustion System Integrity — A correctly fitted flange maintains proper airflow and exhaust routing within the heater, supporting consistent heat output across demanding jobsite conditions.
- Fuel System Safety — Flanges in diesel-fired heater systems are part of the combustion and exhaust pathway; using a correctly rated OEM part helps ensure sealed, leak-free operation in accordance with the original design.
A flange in an indirect-fired air heater serves as a connection and sealing interface between sections of the burner, exhaust, or duct assembly. It ensures that combustion gases remain properly routed and isolated from the clean air supply — which is critical in an indirect heater where exhaust and heated air must never mix. When a flange warps, cracks, or corrodes, it can compromise the seal, reduce heating efficiency, or allow exhaust gases to escape into the airstream. Replacing a worn flange with the correct OEM part restores the integrity of the heater's internal pathway and keeps the unit operating safely and efficiently.
