The Wacker Neuson is a genuine OEM Water Separator Filter designed for the HI1000 Indirect Air Heater and E3000 Ground Heater series. Sourced directly from Wacker Neuson, this filter carries the same part number and construction as the unit installed at the factory, ensuring a direct, compatible replacement for your climate equipment. It fits multiple HI1000 DGM configurations — including electric break and surge brake variants — as well as E3000 6kW Ground Heater models. When fuel system integrity matters on the jobsite, using the correct OEM-specified filter is the straightforward choice.
Key Features
- OEM Fuel-Water Separation Efficiency — Manufactured to Wacker Neuson's original filtration specification, ensuring the correct micron rating and water-separating capacity for these heater and ground heating applications.
- Direct Housing Compatibility — Engineered to seat and seal correctly within the existing filter housing on HI1000 and E3000 units, with no adapter fittings or modifications needed.
- Broad Series Coverage — Fits HI1000 Indirect Air Heater (DGM, electric break, and surge brake variants) and E3000 Ground Heater (6kW LB and LB TC configurations).
- Protects Burner and Fuel Components — A functioning water separator prevents water-contaminated fuel from reaching the burner assembly, protecting injectors and fuel delivery components from corrosion and misfires.
- Fuel System Safety — Proper filtration in diesel-fired heating equipment is critical to consistent ignition and preventing uncontrolled burner behavior; the correct OEM filter maintains the designed fuel flow and separation performance.
A water separator filter sits in the fuel supply line and performs two jobs: it removes particulate debris from the diesel fuel before it reaches the burner, and it separates free water from the fuel stream before that water can cause ignition problems or accelerate corrosion in fuel system components. In diesel-fired indirect air heaters and ground heaters like the HI1000 and E3000 series, consistent, clean fuel delivery is essential to reliable ignition and steady heat output. When this filter becomes clogged or saturated, fuel flow is restricted, burner performance degrades, and water contamination can lead to hard starts, misfires, or damage to downstream fuel components.
