Key Overview of Fleetguard AH1135 Air Filter
The Fleetguard AH1135 air filter is a heavy-duty, high-flow filtration solution engineered for large diesel engines and industrial equipment. Notably, it delivers exceptional airflow and filtration precision, making it ideal for power-dense engines like the Cummins QSK 19 M. Additionally, it supports a wide range of cross-reference part numbers, ensuring versatile compatibility across multiple leading equipment brands. Moreover, its robust construction and large dimensions cater to the high-demand operating conditions of heavy machinery, from construction cranes to generator sets.
Fleetguard, a trusted leader in heavy-duty filtration technology, designs the AH1135 to meet the strictest industry standards. Furthermore, it is built to handle extreme dust loads and high airflow requirements, ensuring consistent engine protection even in the harshest environments. For this reason, it becomes a top choice for equipment operators and fleets seeking reliable, long-lasting air filtration.
Unlike standard air filters that sacrifice flow for filtration, the AH1135 balances high-rated flow with superior contaminant removal. It also fits a diverse range of machinery, from Cummins engines to Gottwald cranes, making it a versatile solution for mixed-equipment fleets.
High-Flow Performance & Filtration Precision
The Fleetguard AH1135 air filter boasts an impressive rated flow of 39.6 m³/min (1398 cfm), catering to the high airflow needs of large diesel engines. Specifically, this high flow rate ensures the engine receives a steady supply of clean air, optimizing combustion efficiency and power output.
In addition to its high flow capacity, it maintains strict restriction control at 17.44 mbar (7 inch H2O). This restriction level prevents airflow bottlenecks, which can reduce engine performance and increase fuel consumption. Moreover, its advanced filter media traps harmful airborne contaminants, protecting critical engine components from premature wear.
Consequently, the AH1135 not only safeguards the engine but also enhances overall operational efficiency. It reduces unplanned downtime and extends the service life of expensive engine parts, delivering long-term value for equipment owners.
Precise Dimensional & Physical Specifications
The Fleetguard AH1135 features carefully calibrated dimensions to ensure a perfect fit with compatible equipment. First and foremost, its overall length measures 655.32 mm (25.80 inch), while its body length is 609.6 mm (24.00 inch)—designed to accommodate large engine air intake systems.
Additionally, it has a maximum body diameter of 343 mm (13.50 inch) and an outlet diameter of 177.8 mm (7.00 inch), ensuring secure integration with air intake housings. These dimensions align with OEM standards, eliminating fitment issues and ensuring a leak-proof seal.
Moreover, the filter weighs 8.500 kg, reflecting its robust construction and high-quality materials. Its volume is 0.095830 m³, optimized to fit the large engine compartments of heavy machinery like the Gottwald HMK 300 and Cummins QSK 19 M.

The Fleetguard AH1135 air filter is compatible with numerous cross-reference part numbers, expanding its versatility across brands. Specifically, these include AC DELCO A1463C, AMERICAN MOTORS CORPORATION SFA1135P, BERGERAT MONNOYEUR E9423, and BIG A 94851.
Other compatible cross-references include CATERPILLAR 3I1034, CUMMINS 3050498, DONSSON GX122, EXMAN SFA1135P, and FREIGHTLINER DNP524838. This wide range of cross-parts simplifies inventory management for repair shops and fleets.
Furthermore, it matches KOHLER 400896003, NELSON 87256N, ONAN 1402413, SDMO 330560504, and VMC AH524838, ensuring operators can easily find a replacement regardless of the original part number.
Fleetguard AH1135 Multi-Brand Equipment Compatibility
The Fleetguard AH1135 is primarily designed for the Cummins QSK 19 M engine, a power-dense diesel engine used in heavy industrial applications. It also fits a range of other high-demand machinery across leading brands, making it highly versatile.
For Gottwald, it suits models including the HMK 300, HMK 3406, and HMK 5506—large cranes commonly used in construction and port operations. For SIMED, it fits the 1000 KVA GROUPE ELECTROGENE, a high-capacity generator set relied on for industrial power supply.
Additionally, its cross-compatibility with Caterpillar, Freightliner, and Kohler equipment means it can serve as a universal replacement filter for mixed fleets, reducing the need to stock multiple filter models.
Fleetguard AH1135 Durability & Heavy-Duty Reliability
The Fleetguard AH1135 is built to withstand the rigors of heavy-duty operation. Its thick, robust body resists physical damage, engine vibration, and environmental exposure—common challenges in construction, mining, and industrial settings.
Unlike lightweight aftermarket filters, it maintains structural integrity even in extreme temperatures and high-dust environments. This durability reduces filter replacement frequency, lowering long-term maintenance costs. Moreover, its high-quality filter media resists clogging, ensuring consistent performance over its service life.
Additionally, its large size and high flow capacity make it ideal for continuous, high-load operation. This reliability ensures that critical equipment—like generator sets and cranes—remains operational when it matters most, minimizing unplanned downtime.
