The Wacker Neuson Filter is a genuine OEM Filter designed for the HI series indirect-fired diesel air heaters and CUB series skid-mounted and mobile indirect-fired air heaters. This is a direct OEM replacement sourced from Wacker Neuson, ensuring it meets the original design specifications for fuel or air filtration on these diesel-powered heating units. It fits a broad range of models including the HI110D, HI110HDD, HI200D, HI200HDD, HI300D, HI300HDD, CUB400, and CUB700 series. Having the correct filter in service keeps combustion and fuel delivery running cleanly in demanding jobsite heating applications.
Key Features
- Genuine OEM Filtration Media — Sourced directly from Wacker Neuson, this filter is built to the original flow-rate and filtration-efficiency specifications for diesel indirect-fired heater systems.
- Drop-In Replacement — Matches the original mounting interface and port sizing of the HI and CUB series heater platforms, so installation swaps out cleanly without adaptation.
- Broad HI and CUB Series Coverage — Compatible with HI110D, HI110HDD, HI200D, HI200HDD, HI300D, HI300HDD, CUB400, and CUB700 skid-mounted and mobile indirect-fired diesel heaters.
- Protects Fuel System Components — A clean, functioning filter prevents particulates from reaching the burner assembly and fuel delivery components, maintaining consistent heat output across the operating cycle.
- Fuel System Safety — A clogged or degraded filter in a diesel-fired heating unit can cause incomplete combustion or fuel delivery faults; replacing it on schedule is a critical step in safe heater operation.
A filter in an indirect-fired diesel air heater removes contaminants from the fuel supply before they can reach the burner assembly or fuel injector components. Clean fuel flow is essential for reliable ignition and steady heat output — particularly in cold-weather construction, concrete curing, or temporary heating applications where uninterrupted performance is critical. When this filter becomes clogged or degraded, fuel delivery is restricted, which can lead to ignition failures, erratic burner cycling, or unburned fuel accumulation in the heat exchanger.
