The Wacker Neuson Filter Foam Reticulated 45Ppi is a genuine OEM air filtration component designed for the GP3800A, GP4000, GP5600A, GP6600A, GP2500A, GPS5600A, and GPS6600A series portable generators. As a direct factory part, the is manufactured to Wacker Neuson's exact material and pore density specifications — 45 pores per inch — ensuring consistent airflow and filtration performance. This foam filter fits across a wide range of GP and GPS series generator configurations, including wheel kit variants, electric start models, EPA-compliant units, and CSA-certified versions. Keeping this filter in good condition is one of the simplest ways to protect the engine and maintain steady output on the job.
Key Features
- 45Ppi Open-Cell Filtration Density — The 45-pores-per-inch reticulated foam structure delivers the airflow balance your generator's engine demands, filtering out particulates without starving combustion.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this filter matches the original foam grade, cell structure, and dimensional profile — no trimming or adaptation needed to seat correctly in the air cleaner housing.
- Broad GP and GPS Series Compatibility — Fits GP2500A, GP3800A, GP4000, GP5600A, GP6600A, GPS5600A, and GPS6600A generators across EPA, CSA, and GFI configurations, including wheel kit and electric start variants.
- Protects Engine from Contaminant Ingestion — A degraded or missing foam pre-filter allows dust and debris to bypass the main air cleaner, accelerating bore wear and shortening engine service life on your portable generator.
- Fuel System Protection Through Clean Air Supply — Consistent, filtered airflow supports correct air-to-fuel ratios, helping maintain stable voltage output and preventing rough running caused by a contaminated or restricted air intake.
The foam reticulated filter serves as the first line of defense in the generator's air intake system, capturing airborne dust, dirt, and debris before they can reach the carburetor and engine internals. The open-cell, reticulated structure allows high air volume to pass through freely while still trapping particles — this balance is critical for maintaining the engine speed and load stability that portable generators depend on for steady electrical output. When this filter becomes clogged, torn, or deteriorated, airflow is restricted, the engine runs rich, and power output drops; in severe cases, contaminants can reach the carburetor jets and cause hard starting or damage requiring costly repairs.
