The Wacker Neuson Fan Guard is a genuine OEM component designed for the HI 90, HI 90HD, HI 300D, and HI 300HD D series indirect-fired diesel air heaters. As a direct OEM replacement, this fan guard is sourced and produced to the same specifications as the original part, ensuring a correct, hassle-free installation. It is compatible across the HI 90 and HI 300 series platforms, making it a straightforward service part for fleet operators running multiple Wacker Neuson heater models. Keep a spare on hand to stay ahead of scheduled maintenance and unplanned repairs on the jobsite.
Key Features
- Genuine OEM Construction: — Fabricated to the original structural and dimensional tolerances required for proper airflow protection on Wacker Neuson indirect-fired diesel heaters.
- Direct Bolt-On Replacement: — Mounts to the same attachment points as the original guard, requiring no modification to the heater housing or fan assembly.
- Broad HI Series Compatibility: — Fits HI 90, HI 90HD, HI 300D, and HI 300HD D diesel indirect air heaters, consolidating a single part number across multiple models in the lineup.
- Protects Fan Integrity: — A correctly fitted fan guard prevents contact with the rotating fan blade, maintaining proper airflow velocity and protecting the internal fan from impact damage during operation and transport.
- Personnel Safety: — The fan guard serves as a physical barrier between operators and the spinning fan assembly, an important safety feature on heaters used in occupied worksites, tents, and enclosed job trailers.
The fan guard on an indirect-fired air heater shields the internal combustion air fan from physical contact and debris ingestion while directing airflow efficiently through the heat exchanger. Without an intact guard, the fan blades are exposed to accidental contact during operation and vulnerable to damage from loose material on the worksite. A missing or damaged fan guard can also disrupt the designed airflow pattern, reducing heating output and putting stress on the fan motor over time.
