The Wacker Neuson Fan is a genuine OEM component designed for the HDR 115 Direct Fired Radiant Heater. Sourced directly through the Wacker Neuson parts network, this fan is manufactured to the exact tolerances required to maintain proper combustion airflow and heat distribution in the HDR 115. Replacing a worn or failed fan with the correct OEM part ensures the heater performs as intended without guesswork on fitment or output compatibility.
Key Features
- OEM-Matched Blade Geometry — Engineered to the exact pitch and diameter spec required by the HDR 115 combustion chamber for consistent, controlled airflow.
- Direct Drop-In Replacement — Matches the original mounting configuration and shaft interface, allowing straightforward removal and reinstallation.
- Confirmed Fitment — Verified for the HDR 115 Direct Fired Radiant Heater, so you can order with confidence.
- Sustained Heat Output — A properly functioning fan maintains the air-to-fuel ratio needed for efficient combustion; a degraded fan can cause uneven heating or heater shutdown.
- Genuine Wacker Neuson Quality — Built and validated to the same production standards as the original component installed at the factory, using materials suited to the thermal environment inside a direct-fired heater.
The fan in a direct-fired radiant heater is responsible for drawing in combustion air and pushing heated air out into the work area. Without adequate airflow, the burner cannot maintain a stable flame, which leads to inefficient fuel burn, inconsistent heat output, or automatic safety shutoff. Over time, fan blades can crack, warp, or become unbalanced from heat stress and debris exposure — any of these conditions will compromise heater performance and can trigger protective cutoffs on the unit.
