Product Features

Integrates progressive three-stage fine filtration with advanced Balanced Charge Agglomeration technology. It extends contaminant capture capability down to the sub-micron range, rapidly intercepting ultra-fine suspended particles and restoring oil cleanliness to stringent international standards (e.g., NAS 1638 / ISO 4406).
Sub-Micron Balanced Charge & Progressive 3-Stage Filtration
Integrates progressive three-stage fine filtration with advanced Balanced Charge Agglomeration technology. It extends contaminant capture capability down to the sub-micron range, rapidly intercepting ultra-fine suspended particles and restoring oil cleanliness to stringent international standards (e.g., NAS 1638 / ISO 4406).
Specifically targets and actively removes dissolved oxidation gums, soft contaminants, and varnish deposits that standard mechanical filters miss. It thoroughly eliminates sluggish movement and sticking in high-precision servo and proportional valve spools, deep-cleaning internal piping to restore full control responsiveness.
Varnish & Oxidation Gum Elimination to Prevent Valve Sticking
Specifically targets and actively removes dissolved oxidation gums, soft contaminants, and varnish deposits that standard mechanical filters miss. It thoroughly eliminates sluggish movement and sticking in high-precision servo and proportional valve spools, deep-cleaning internal piping to restore full control responsiveness.
Features an integrated intelligent monitoring interface that continuously tracks and displays critical operational metrics in real time: pre-filter pressure, collector pressure, high-voltage electrostatic field voltage, and leakage current. Provides instant diagnostics and element replacement alerts for maximum operational safety.
Real-Time Data Telemetry & Electrostatic Field Monitoring
Features an integrated intelligent monitoring interface that continuously tracks and displays critical operational metrics in real time: pre-filter pressure, collector pressure, high-voltage electrostatic field voltage, and leakage current. Provides instant diagnostics and element replacement alerts for maximum operational safety.
Employs a non-intrusive bypass "kidney-loop" circulation design, purifying reservoir fluid continuously without causing pressure drops or interfering with running host machinery. Delivers 24/7 unattended reliability, extended consumable lifespan, and low energy consumption, substantially slashing long-term maintenance expenditure.

Delivers 24/7 unattended reliability, extended consumable lifespan, and low energy consumption, substantially slashing long-term maintenance expenditure.

How It Works

Balanced Charge Agglomeration

Positive and negative electrodes are placed in two parallel flow paths through the non-conductive fluid, charging the particulate contaminants — one path with a positive (+) charge and the other with a negative (-) charge.


The oppositely charged particles are then remixed, attract each other and agglomerate into larger clusters, so that fine particles that are otherwise difficult to filter can be easily captured and removed.
