The Wacker Neuson Air Duct Tube is a genuine OEM component designed for the HDR 155 Direct Fired Radiant Heater and HDR 45 direct-fired radiant heaters. Sourced directly from Wacker Neuson, this part meets the exact design specifications of the original, ensuring a correct fit within the heater's airflow system. If your HDR-series heater is showing restricted heat output or signs of duct wear or damage, replacing the Air Duct Tube restores proper airflow and combustion performance.
Key Features
- Genuine OEM Airflow Integrity — Manufactured to Wacker Neuson's original duct geometry and material spec, ensuring the correct volume and direction of heated air reaches the output.
- Direct Drop-In Replacement — Engineered to align with the existing mounting points and connections in HDR-series heaters, allowing straightforward installation without modification.
- Confirmed HDR-Series Fitment — Verified for the HDR 155 Direct Fired Radiant Heater and HDR 45, covering two key models in the Wacker Neuson radiant heater lineup.
- Restored Heat Distribution — A damaged or collapsed air duct tube disrupts combustion airflow, reducing heating efficiency; a fresh 5200011782 brings output back to rated performance.
- Combustion Safety Compliance — Correct duct routing is critical to safe burner operation in direct-fired heaters; using the genuine OEM tube maintains proper air-to-fuel delivery and prevents uncontrolled heat buildup.
The air duct tube channels combustion air through the heater's burner assembly and directs the heated airflow toward the output end of the unit. In a direct-fired radiant heater like the HDR 155 and HDR 45, this tube is a structural part of the airflow path — without it functioning correctly, the burner cannot maintain a stable flame or deliver consistent heat output. A cracked, deformed, or missing duct tube can cause uneven heating, burner lockout, or potentially unsafe operating conditions, making timely replacement essential for reliable cold-weather operations.
