The Fleetguard AF1828 is a heavy-duty axial-seal primary air filter built for high-airflow industrial and construction engines. The element draws air outside-in through pleated cellulose media and seals into the housing with a moulded urethane gasket, achieving 99.9% full-life efficiency. With a 525.75 mm overall length and 306.80 mm largest outer diameter it is a long-version replacement for the shorter AF25762, suited to single-stage and two-stage air-cleaner systems on construction equipment, mobile compressors and large agricultural windrowers. The element ships with a 3830497S bolt seal for installation on housings that require it.
