High Dirt-Holding Capacity
Holds up to 30% more contaminants than conventional mesh filters, extending service intervals.
Consistent Filtration Accuracy
The sintered structure maintains stable porosity under pressure and thermal cycling.
Corrosion Resistance
Compatible with oil, water, and mixed-phase systems, ensuring long-term integrity in harsh environments.
Reusable and Backflushable
Supports intermittent backflushing, enabling cleaning and reuse in suitable systems.
This compact sintered bronze filter is ideally suited for:
Bearing Lubrication Systems
Ensures clean lubricant flow, reducing friction and wear in high-speed assemblies.
Small Hydraulic Power Units (HPUs)
Protects sensitive valves and components from particulate contamination.
Pneumatic Instrumentation
Removes fine contaminants from air lines feeding control instruments and actuators.
Fuel Pre-Filtration
Pre-cleans diesel, kerosene, or aviation fuels before reaching primary filters or injection systems.
Cleaning Method
Recommended: ultrasonic cleaning with isopropanol for deep pore purification.
Replacement Trigger
Suggested change when differential pressure exceeds 2 bar (ΔP > 2 bar).
Average Service Life
Typically 9 to 12 months under standard usage conditions.
