Wacker Neuson 5200022112 Diesel Pre-Heated Filter

The Wacker Neuson Diesel Pre-Heated Filter is a genuine OEM component designed for the HDR 155 Direct Fired Radiant Heater. As a direct factory replacement, this filter installs exactly as the original, ensuring the fuel system operates within spec with no guesswork on compatibility. Sourced directly through authorized Wacker Neuson supply channels, this part carries the same quality assurance as the unit that shipped with your machine. If you're servicing an HDR 155 and need a dependable fuel filter replacement, this is the correct part.

Key Features

• Genuine OEM Fuel Filtration Integrity — Manufactured to the same filtration specification as the original, ensuring contaminants are kept out of the fuel circuit in cold-weather diesel heating applications.
• Pre-Heated Design for Cold-Climate Operation — The integrated pre-heating function prevents diesel gelling and wax crystal buildup in low-temperature environments, maintaining consistent fuel flow to the burner.
• Direct Drop-In Replacement — Engineered to the exact mounting and connection dimensions of the original HDR 155 filter, fitting the fuel line without adaptation or modification.
• Verified Fitment for the HDR 155 Direct Fired Radiant Heater — Confirmed compatible with the HDR 155 series, making part selection straightforward for service technicians and operators.
• Protects Burner Performance — A clean, unobstructed fuel supply keeps the radiant heater igniting reliably and burning efficiently; a clogged or failed filter can cause hard starts, burner lockout, or uneven heat output.

The diesel pre-heated filter sits in the fuel supply line and performs two critical jobs: it removes particulates and water contamination from the diesel before it reaches the burner, and it applies heat to the incoming fuel to prevent cold-weather gelling that can restrict or block fuel flow entirely. In direct-fired radiant heaters like the HDR 155, reliable fuel delivery is essential to consistent ignition and steady heat output. When this filter becomes clogged or loses its heating function, the heater may fail to start, run erratically, or shut down on safety lockout — making timely replacement a straightforward way to keep the unit running through demanding cold-weather work.
