Fleetguard HF7520 Hydraulic Filter

The Fleetguard HF7520 is a high-performance cartridge hydraulic filter built for heavy‑duty hydraulic systems. It uses premium microglass media to efficiently capture solid particles, sludge, and wear debris, protecting pumps, valves, cylinders and other critical components from abrasion and premature failure. Engineered to ISO standards, it delivers stable filtration and consistent fluid cleanliness for demanding operations.
Its robust cartridge design features reinforced end caps, reliable gaskets, and optimized pleating for high dirt‑holding capacity and low pressure drop. The filter fits standard OEM housings and suits excavators, loaders, mining machinery, and other heavy equipment, ensuring easy installation and dependable sealing under pressure and vibration.
As a genuine Fleetguard component, the HF7520 supports extended service intervals, reduces maintenance downtime, and preserves hydraulic system efficiency. It helps extend oil life, lower operating costs, and maintain equipment reliability in harsh working environments.

Advantages of HF7520 Hydraulic Filter

The HF7520 uses high‑performance microglass media rated at 5–6 microns with a Beta efficiency of βx≥1000. It effectively removes fine particles that cause rapid wear in precision hydraulic parts, maintaining clean fluid and stable system performance throughout the service cycle.
Optimized pleated structure provides a large filtration area and exceptional dirt‑holding capacity. This extends service life, reduces replacement frequency, cuts maintenance labor, and minimizes unplanned downtime for fleets and heavy equipment.
Carefully engineered flow characteristics keep pressure loss to a minimum. Stable pressure supports responsive machine operation, reduces energy consumption, and avoids performance issues linked to flow restriction, even in cold‑start conditions.
Reinforced construction and high‑integrity seals withstand high pressure, vibration, and temperature variations. Precision dimensions ensure perfect OEM compatibility for direct fitment, preventing bypass leaks and delivering consistent protection in harsh construction and mining environments.
