FILTERS

Our Hydraulic Filters are manufactured and tested in absolute compliance with ISO multi-pass test standards. Utilizing advanced micro-glass fiber media and specialized structural multi-layer synthetic configurations, our elements deliver a high Beta ratio ($beta_x ge 200$), ensuring deep particulate separation and stable fluid cleanliness under severe cyclic flow stresses.

Each serves a specific architectural role: Suction Filters protect the hydraulic pump from large debris entry from the reservoir; Pressure Filters are heavy-duty, inline housings positioned downstream of the pump to shield ultra-sensitive servo or proportional valves; Return Filters mount at the reservoir tank entry to capture all particulate accumulation generated by mechanical cylinder or motor friction before it re-enters the fluid storage tank.

Nominal filtration indicates an arbitrary percentage of particle retention (typically 50% to 70%), which permits harmful micro-abrasives to continuously pass through the system. Absolute filtration ratings, backed by verified ISO standards, guarantee the capture of up to 99.5% or higher of target micronic contaminants (e.g., $3 mu m, 10 mu m$, or $25 mu m$) at the stated micron dimension.

To prevent the filter element from entering automated bypass mode, we supply robust monitoring indicators. Installers can specify traditional Visual pressure gauges for manual fleet auditing, Electrical differential switches for telemetry signaling, or dual visual-electrical indicator mechanisms that alert operators when differential pressure limits are reached.

During extreme cold-start operations, hydraulic fluid viscosity increases dramatically, creating a temporary artificial pressure spike across the filter element. Our integrated bypass valves open precisely at calibrated cracking thresholds (typically 1.5 to 3 bar depending on housing configuration) to prevent structural element collapse, ensuring continuous oil circulation until operating temperatures stabilize.

Our filter housings conform strictly to international standardizations, providing high-strength machined ports with options for standard BSP parallel threads, NPT configurations, metric sizes, or SAE split-flange coupling configurations. This ensures direct inline mechanical integration without auxiliary adaptors.

Absolute micron-glass filtration is critical for any circuit using high-pressure gear, vane, or variable piston pumps. This incorporates heavy mobile construction excavators, tipping commercial transport fleets, industrial concrete pumps, injection molding setups, and scrap metal waste recycling balers.

As hydraulic cylinders extend and retract, the internal oil level in the reservoir fluctuates constantly, drawing atmospheric air into and out of the tank. Hayneks tank-top air breathers utilize high-efficiency spin-on elements to capture incoming airborne dust and moisture, stopping contaminants from corrupting the fluid circuit from above.

Yes. Our replacement filter elements are engineered to achieve absolute dimension and structural media equivalence to dominant global OEM brands. Matching exact end-cap heights, structural inner support bypass designs, and internal seal materials, they function as premium, cost-effective drop-in drop replacements.

While clogging indicators offer the safest real-time feedback, as a standard fleet maintenance rule, we recommend replacing high-pressure elements after the initial 100 hours of system commissioning to catch manufacturing debris, and every 500 to 1000 operating hours thereafter depending on environmental conditions.
