J221-78B-041000 Suction Oil Filter is a premium universal hydraulic filter for heavy-duty construction machinery, industrial hydraulic systems, and agricultural equipment. It focuses on all-round hydraulic system protection and clean fluid circulation, ensuring stable operational performance and extended component life in high-pressure, harsh working environments.
It delivers superior filtration efficiency, capturing metal particles, wear debris, and contaminant residues as small as 3 microns with high capture rate. This eliminates contamination-induced wear on hydraulic pumps, valves, and cylinders, avoiding system blockages and premature hydraulic failures.
Crafted with high-performance composite media, it balances thorough contaminant removal with low flow resistance. Its optimized structure maintains consistent hydraulic flow, enhancing system response speed and operational smoothness while reducing energy loss.
Thoughtfully engineered for universal compatibility, it installs easily without extra adjustments. Its precision sealing structure prevents unfiltered fluid bypass, fully protecting hydraulic systems across various equipment types.
Constructed from high-strength, pressure-resistant, and corrosion-proof materials, it withstands extreme hydraulic pressures, intense vibration, and temperature variations (-30°C to +110°C), maintaining reliable guard performance over extended use.
More than a filter – it’s a universal hydraulic system protection core. It boosts operational durability, reduces maintenance frequency, and upholds rigorous quality standards for high-performance hydraulic filtration.
