The Wacker Neuson is a genuine OEM Lower Frame designed for the HI750G, HI750GM, and HI900G series indirect-fired air heaters. As a factory-sourced structural component, it meets the original engineering specifications for these skid-mounted and portable heating units. This part is confirmed across multiple HI750 and HI900 configurations, including natural gas, LP, and dual-fuel variants. If your indirect heater has sustained frame damage or requires structural restoration, the is the correct OEM replacement to restore integrity.
Key Features
- Genuine OEM Structural Integrity — Manufactured to Wacker Neuson's original design tolerances, ensuring the frame maintains correct load distribution and component alignment across all supported heater configurations.
- Broad HI-Series Compatibility — Fits multiple HI750G, HI750GM, and HI900G configurations, including skid-mounted, 3×16, 4×12, and factory-installed option builds.
- Direct Bolt-In Replacement — Engineered to match the original mounting geometry, allowing the heater's burner assembly, fuel components, and housing to reattach without modification.
- Supports Stable Heater Operation — A sound lower frame keeps burner and heat exchanger components properly positioned; a damaged or distorted frame can cause misalignment that affects combustion efficiency and airflow.
- Verified OEM Part Number — Cross-referenced against Wacker Neuson's official parts documentation for the HI750 and HI900 indirect air heater families, giving you confidence in fitment before the part ships.
The lower frame is the primary structural base of the indirect-fired air heater, providing the foundation on which the burner assembly, fuel system components, heat exchanger, and outer housing are mounted and supported. It absorbs the stresses of transport, skid deployment, and continuous operation, keeping all internal components in their correct positions relative to one another. When the lower frame is bent, cracked, or corroded, it can compromise the alignment of combustion and airflow components, leading to uneven heat output, increased wear on attached parts, and potential safety concerns during operation.
