The Wacker Neuson Fan is a genuine OEM component designed for the HDR 115 Direct Fired Radiant Heater. Sourced directly from Wacker Neuson, this fan carries the same part number and build specification as the original unit installed at the factory. It is a direct replacement for the HDR 115, making it the correct choice when the original fan needs to be swapped out. Trust the to restore your heater's airflow performance to its original operating condition.
Key Features
- Genuine OEM Airflow Specification — Built to the exact blade geometry and motor-mount tolerances specified for the HDR 115, ensuring consistent air movement across the radiant heat exchanger.
- Direct Drop-In Replacement — Matches the original mounting configuration of the HDR 115 fan assembly, so installation follows the same steps as the factory unit.
- HDR 115 Compatibility Confirmed — Verified fitment for the HDR 115 Direct Fired Radiant Heater (Model HDR115_5100018592).
- Sustained Heat Output — A properly functioning fan maintains the correct airflow over the radiant element; a worn or failed fan leads to overheating, uneven heat distribution, and potential heater shutdown.
- Fuel System Safety Relevance — In a direct-fired radiant heater, adequate fan operation is critical to safe combustion airflow; replacing a degraded fan with a genuine OEM part supports correct burner operation and reduces the risk of combustion irregularities.
The fan in a direct fired radiant heater drives the airflow that carries heat from the radiant element out into the work area. It also plays a role in controlling combustion conditions within the heater body, helping to maintain the correct air-to-fuel balance for clean, efficient burning. When the fan weakens or fails, heat output drops, the heater may cycle off on thermal protection, or combustion can become unstable — all of which interrupt work in cold-weather jobsite conditions.
