The Wacker Neuson Air Filter Seal is a genuine OEM component designed for a broad range of Wacker Neuson equipment, including CT36-9 and CT48-9 concrete power trowels, PT3 trash pumps, GP4000 and GPi4300 portable generators, and BFS series floor saws. As a genuine OEM part, is manufactured to the same specifications as the original seal fitted at the factory, ensuring a correct interface between the air filter housing and the engine intake. This seal is the exact replacement for all listed CT, PT, GP, GPi, GPSi, and BFS model variants covered by this part number.
Key Features
- OEM-Grade Sealing Material — Produced to the original compound and compression specification, maintaining an airtight barrier between the filter element and housing across all covered models.
- Drop-In Housing Fit — Engineered to seat directly into the original air filter housing without trimming or adjustment, matching the OEM profile exactly.
- Wide Cross-Equipment Compatibility — A single part number covers CT36-9 and CT48-9 trowels, PT3 trash pumps, GP4000 / GPi4300 / GPSi4300 generators, and BFS 914, 935, 940, and 16-inch floor saws.
- Protects Engine Intake Integrity — A properly seated air filter seal prevents unfiltered air, dust, and debris from bypassing the filter element and entering the engine — a leading cause of premature bore and valve wear.
- Fuel System Safety Relevance — A failed or compressed seal allows contaminant ingestion that can disrupt air-fuel ratios, contributing to running issues and potential engine damage on fuel-sensitive machines.
The air filter seal forms the compression gasket between the air filter element or cover and the engine's intake housing. Its job is to create a dust-tight boundary so that all incoming combustion air passes through the filter media rather than around it. When this seal hardens, tears, or loses its compression set, unfiltered air bypasses the element entirely — accelerating internal engine wear and causing erratic running, difficult starts, or increased fuel consumption. On multi-application machines like generators, trowels, pumps, and saws that often operate in dusty or debris-heavy environments, a serviceable air filter seal is a critical maintenance item.
