03140253 | High-Pressure Hydraulic Oil Filter
Glass Fiber Composite Media for Grove Cranes, JLG Lifts & Bobcat Telehandlers | Precision Replacement for Hydac 0055D010ON & Fleetguard HF35555
03140253 Description
The AYREST 03140253 Hydraulic Pressure Filter represents the pinnacle of micro-particle capture technology for modern high-pressure hydraulic circuits. Utilizing imported glass fiber composite media, this element provides a multi-stage filtration depth that standard cellulose filters cannot match. Its core advantage lies in a reinforced internal metal support structure, which allows the filter to maintain a Δ Collapse Pressure of 20 bar, ensuring the media remains structurally intact even during extreme system pressure spikes or cold-start viscosity surges.
Engineered specifically for high-frequency operating conditions found in aerial work platforms and mobile cranes, the 03140253 features an optimized deep-bed filtration layer. This design ensures a consistent β200 @ 10µ efficiency rating, effectively shielding precision hydraulic actuators, servo valves, and sealing surfaces from abrasive wear. By maintaining ultra-clean oil, this filter minimizes internal leakage risks and significantly extends oil change intervals for high-value machinery such as Grove GMK cranes and Manitou telehandlers.
With a wide operating temperature range of -30°C to +100°C and premium Nitrile (NBR) seals, the 03140253 is built for the most punishing environments-from sub-zero forestry work in Fendt tractors to the high-heat industrial cycles of DMG Mori CNC machines. It is the ideal core filtration solution for ensuring continuous operation and reducing unplanned downtime in global fleets.

03140253 Technical FAQ
Q1: What makes Glass Fiber media superior to Cellulose for high-pressure systems?
A: Cellulose fibers are thick and irregular, while Glass Fiber is inorganic, much thinner, and uniform. This allows for a higher pore density, capturing 99.9% of particles at 12 microns (β1000) without significantly increasing flow resistance. Glass fiber also does not swell when exposed to water or chemical additives in hydraulic oil.
Q2: Why is the "Collapse Pressure" rating critical for JLG and Grove equipment?
A: Lifting equipment involves massive load shifts that create sudden pressure pulses in the return and pressure lines. A lower-quality filter could collapse inward during these pulses, allowing unfiltered oil to bypass directly into the servo valves. Our 20-bar collapse rating ensures the filter stays functional under these surges.
Q3: Does the 03140253 prevent valve "stiction" in CNC and precision machinery?
A: Yes. "Stiction" (static friction) in hydraulic valves is usually caused by fine silt buildup. Our 10-micron nominal filtration captures this silt before it can settle on valve spools, ensuring the smooth, lightning-fast response required by machines like the DMG Mori CTX series.
Q4: Can this filter replace Hydac 0055D010ON without modifications?
A: Absolutely. It is a 1:1 dimensional and performance match. It fits the same Hydac pressure housing and meets or exceeds the original manufacturer's flow and filtration specifications.
Q5: How does this filter contribute to "Green" operations?
A: By capturing more contaminants and maintaining structural integrity longer, the 03140253 extends the service life of the hydraulic oil itself. This reduces the frequency of oil disposal and new oil purchases, lowering the overall environmental footprint of the fleet.
