High Efficiency Fuel Cleaning:

The M3 Filter Polisher is designed for high efficiency fuel cleaning.  Positive displacement pumps flow fuel through a multi-phase particulate and water coalescing filter to clean fuel to ISO 18/16/13 Standard or better.

Comprehensive Control and Monitoring:  

The system controller allows for scheduling of filtration cycles to meet the facilities operating needs.  Filter differential pressure, filter water, pump flow, and leak detection sensors are integrated with the controller.  The system integrates with BMS and SCADA systems using BACnet or Modbus communication.

Adaptable to User Requirements:

The M3 Filter Polisher can be equipped with special equipment to meet user requirements for water holding tanks, magnetics, and final filtration.
