The Wacker Neuson Fan Guard is a genuine OEM component designed for the HI 400HD G, HI 400HD D, HI 120, and HI 120HD indirect-fired air heaters. As a direct factory replacement, this fan guard installs exactly as the original, maintaining the correct clearance and airflow geometry around the combustion air fan. Sourced directly from Wacker Neuson, part number is the correct OEM specification for these heater models and carries the same fit and material standards as the part it replaces.
Key Features
- OEM-Grade Steel Construction — Manufactured to Wacker Neuson's original material and dimensional spec, ensuring the guard holds its shape under the thermal cycling and vibration typical of indirect-fired heater operation.
- Drop-In Installation — Mounts directly to the original fastener points on the fan housing with no drilling, cutting, or bracket modification needed.
- Broad HI Series Compatibility — Confirmed fit across the HI 400HD G, HI 400HD D, HI 120, and HI 120HD indirect air heater lineup, covering both gasoline and diesel variants in this family.
- Sustained Airflow Performance — A correctly fitted fan guard channels combustion air efficiently into the burner assembly; a damaged or missing guard disrupts airflow, leading to inconsistent heat output and potential heater shutdowns.
- Personnel and Equipment Safety — The fan guard provides a physical barrier between rotating fan components and personnel or debris, a critical protection point on open-air jobsite heaters operating in high-traffic environments.
The fan guard on a Wacker Neuson indirect-fired air heater shields the combustion air fan from physical contact and debris ingestion while helping direct airflow through the burner intake. Without a properly seated guard, the fan is exposed to damage from foreign objects, and airflow turbulence can disrupt the air-to-fuel mixture, causing incomplete combustion or burner lockout. On a workhorse like the HI 400HD or HI 120 series — where consistent heat output is critical in cold-weather concrete curing, thawing, or enclosure heating applications — keeping this component intact is essential to uninterrupted operation.
