Air Filter | DPU3050H, DPU3750H

The Wacker Neuson 108903 Air Filter is a genuine OEM air filter designed for a wide range of Wacker Neuson equipment, including DPU series reversible vibratory plate compactors, PT2H and PT3H self-priming centrifugal trash pumps, HSH350 hydronic surface heaters, and E1100 ground heaters. As a direct OEM replacement, part 108903 is manufactured to the same specifications as the original component, ensuring a correct, consistent fit across every compatible model. This part covers an extensive fitment range — from DPU 2440H and DPU 2540H through the DPU 3750H and DPU 3760H families, as well as DPS1850H and DPS2050H plate compactors — making it a practical stock item for operators and service technicians running mixed Wacker Neuson fleets.

Key Features

• OEM Filtration Media: — Built to the same filtration efficiency rating as the factory-installed filter, protecting the engine from airborne particles, dust, and debris on active worksites.
• Drop-In Replacement: — Designed to seat and seal correctly in the OEM air filter housing across all listed models, with no trimming or adaptation needed.
• Broad Cross-Family Fitment: — A single part number covers DPU and DPS reversible and single-direction vibratory plate compactors, PT2H and PT3H trash pumps, HSH350 and E1100 surface and ground heaters.
• Engine Protection at Every Service Interval: — A clean, properly seated air filter maintains the correct air-to-fuel mixture, supporting full engine output and fuel efficiency. A clogged or degraded filter restricts airflow, causes rough running, and accelerates internal engine wear.
• Fuel System Integrity: — Maintaining a clean air supply is critical to preventing contaminant ingestion into the carburetor and fuel system — particularly on equipment operating in sandy, dusty, or demolition-site conditions.

The air filter is the engine's first line of defense against airborne contaminants. It traps dust, grit, and debris before they can enter the carburetor and combustion chamber, preventing premature wear on pistons, cylinders, and valve components. On equipment like vibratory plate compactors and trash pumps that regularly operate in dirty, dusty environments, the air filter works hard and should be inspected and replaced at every recommended service interval. A restricted or damaged filter starves the engine of clean air, causing hard starting, loss of power, increased fuel consumption, and — if left unchecked — accelerated internal engine damage.
