HYDRAULIC FILTERS
PRECISION DEFENSE
99.99% filtration efficiency with integrated water separation. Rated to 450 PSI for high-pressure circuits — protecting pumps, valves, actuators and servo components from particulate abrasion, water ingress and fluid degradation.
HYDRAULIC FILTERS — HIGH-COLLAPSE GLASS FIBER MEDIA
Total Hydraulic Circuit Asset Protection
ELIMFILTERS® hydraulic filters are engineered for the most demanding fluid power circuits. The high-collapse glass fiber media achieves 99.99% single-pass efficiency, capturing particles down to 3 microns absolute before they reach precision-clearance components. A coalescing water separation stage removes free and emulsified water from the fluid stream — the primary cause of hydraulic pump cavitation, valve spool corrosion and fluid oxidation acceleration. Rated to 450 PSI collapse pressure, these elements hold structural integrity under the full shock-load range of mobile and industrial hydraulic systems.

THE COST OF CONTAMINATED HYDRAULIC FLUID
What ELIMFILTERS® Prevents
Pump scoring and cavitation — particles at 3–5 micron destroy piston and vane surfaces faster than any other wear mode
Servo valve spool seizure — 5 micron clearances mean a single hard particle causes a stuck valve and a dead circuit
Fluid oxidation acceleration — water contamination catalyzes acid formation, multiplying fluid replacement costs
Seal extrusion and bypass — degraded fluid attacks elastomeric seals, creating leak paths across the entire circuit
Cylinder scoring and rod seal failure — particulate contamination on rod surfaces destroys dynamic seals in one stroke
Without Adequate Filtration
ISO 4406 cleanliness code deteriorates rapidly — fluid contamination reaches critical levels within hours of operation
Pump efficiency drops 15–30% before catastrophic failure — measured power loss on every work cycle
Proportional valve response degrades — precision position control becomes impossible in mobile equipment
Fluid change intervals collapse from 4,000 hours to under 500 — maintenance cost multiplication across the fleet
Component replacement cascades — one contaminated pump destroys the entire downstream circuit

ABSOLUTE FILTRATION RATING
Precision protection for servo valves, proportional valves and piston pumps with 3–5 micron clearances
Results verified in construction, mining, agriculture, marine and industrial manufacturing hydraulic systems operating under continuous high-pressure load.
INDUSTRIAL APPLICATIONS
CONSTRUCTION
Excavators, cranes and hydraulic hammers. Protects high-pressure circuits from particulate ingression during boom, stick and bucket operations on contaminated job sites.
MINING
Hydraulic roof supports, drill rigs and haul truck suspensions. Guards servo valves and piston pumps in circuits operating at 3,000–5,000 PSI under continuous shock loads.
AGRICULTURE
Tractors, harvesters and precision planting equipment. Maintains proportional valve accuracy for GPS-guided implement control and hydraulic lift systems.
MARINE
Deck machinery, steering gear and stabilizer systems. Removes water contamination from marine hydraulic circuits exposed to condensation and sea spray.
MANUFACTURING
Hydraulic presses, injection molding machines and automated assembly. Sustains servo valve precision and cylinder positioning accuracy in high-cycle production environments.
HEAVY TRANSPORT
Tipper trucks, semi-trailers and refuse vehicles. Defends hydraulic cylinders and directional control valves against contaminated fluid from extended service intervals.
