The Wacker Neuson Guard is a genuine OEM component designed for the HI 400HD D and HI 120HD indirect-fired air heaters. Sourced directly from Wacker Neuson, this guard matches the original specification and installs as a direct replacement with no fitment uncertainty. It is verified for use across the HI 400HD D and HI 120HD heater models, making it a straightforward choice when servicing either unit.
Key Features
- Genuine OEM Construction — manufactured to the original design spec, ensuring the guard seats and secures exactly as the factory-installed component does.
- Direct-Fit Replacement — matches the original mounting points on the HI 400HD D and HI 120HD, allowing a clean swap during scheduled service or repair.
- Confirmed Heater Fitment — verified compatible with the HI 400HD D Indirect Air Heater and the HI 120HD, covering both models in the HI heavy-duty indirect heater range.
- Protective Function Restored — a correctly installed guard shields critical heater components from accidental contact and debris, maintaining safe, uninterrupted heating output on the jobsite.
- Safety-Relevant Component — guards on indirect-fired heaters help prevent unintended contact with hot surfaces and moving or energized components; replacing a damaged or missing guard promptly supports safe heater operation.
A guard on an indirect-fired air heater serves as a physical barrier that protects both the operator and internal components from accidental contact, impact, and debris ingestion. On units like the HI 400HD D and HI 120HD, which run continuously in demanding construction and industrial environments, a compromised or missing guard can expose combustion and heat-exchange components to damage and create a contact hazard for workers nearby. Replacing a cracked, bent, or missing guard restores the heater's intended level of protection and keeps the unit operating within its designed safety parameters.
