The Wacker Neuson Pipe is a genuine OEM component designed for the HI series indirect-fired diesel air heaters, including the HI110D, HI110HD D, HI200D, HI200HD D, HI300D, HI300HD D, HI400HD D, HD50, HD70, HI35, HI90, HI90HD, HI120, and HI120HD models. As a direct OEM replacement, part is manufactured to the same specifications as the original, ensuring a correct installation without modification. This pipe is a critical component within the heater's air or fuel flow path, and using the correct part keeps the unit operating as intended across demanding jobsite conditions.
Key Features
- Genuine OEM Construction — Manufactured to the same dimensional and material standards as the original, ensuring correct flow characteristics and connection integrity specific to HI series indirect air heaters.
- Direct Replacement Fit — Matches the original routing and connection points, dropping in as a straight swap with no reworking of adjacent components.
- Broad HI Series Compatibility — Fits a wide range of Wacker Neuson indirect diesel air heaters, from the compact HI35 and HI90 through to the heavy-duty HI300HD D and HI400HD D units.
- Supports Consistent Heat Output — A correctly fitted pipe maintains the designed airflow or fuel delivery path, allowing the heater to reach and sustain its rated output in cold-weather operations.
- Fuel System Integrity — On diesel-fired heaters, a cracked or deteriorated pipe can allow fuel or combustion gases to escape the intended circuit; replacing a worn pipe promptly restores safe, contained operation.
On an indirect-fired diesel air heater, internal pipes route either combustion air, exhaust gases, or fuel between key components within the burner and heat exchanger assembly. Maintaining an intact pipe ensures that heat transfer and fuel delivery occur along the correct path, keeping exhaust separated from the clean air supply delivered to the space being heated. When a pipe cracks, corrodes, or develops a leak, the heater may lose efficiency, fail to reach temperature, or trigger a safety shutoff — making timely replacement essential for consistent performance in cold-weather construction, concrete curing, and enclosed-space heating applications.
