The Wacker Neuson Air Intake is a genuine OEM component designed for the HI 400HD G and HI 400HD D indirect-fired air heaters. Sourced directly from Wacker Neuson, this part carries the same specifications as the original component installed at the factory. It is confirmed compatible with both the gas-powered HI 400HD G and diesel-powered HI 400HD D models, making it the straightforward choice for operators servicing either unit in the HI 400HD series.
Key Features
- Genuine OEM Airflow Geometry — Manufactured to the exact inlet dimensions and flow path of the original, ensuring the burner assembly receives the correct volume and velocity of combustion air.
- Direct-Fit Replacement — Matches the original mounting points and connection interfaces on both HI 400HD G and HI 400HD D heaters for a straightforward swap during service.
- Dual-Model Coverage — A single part number covers both the gas-powered HI 400HD G and the diesel-powered HI 400HD D variants of Wacker Neuson's heavy-duty indirect air heater line.
- Combustion Efficiency Maintained — A correctly functioning air intake keeps the air-to-fuel ratio within design parameters, supporting consistent heat output and efficient fuel consumption across demanding jobsite conditions.
- Fuel System Safety Compliance — Proper intake airflow is critical to clean, complete combustion; a cracked, blocked, or damaged intake can cause incomplete burn, carbon buildup, or unsafe heater operation. Replacing with a genuine OEM part restores safe operating conditions.
The air intake on an indirect-fired heater channels outside air into the combustion chamber where it mixes with fuel to sustain the burner flame. On indirect heaters like the HI 400HD series, the combustion gases are kept entirely separate from the heated air delivered to the space, so a properly sealed and unobstructed intake is essential to both heating performance and safe operation. When the air intake is cracked, clogged, or worn, combustion efficiency drops — leading to uneven heat output, increased fuel consumption, or burner lockout.
