Demand Flow Technology

AirDog® II-4G Fuel Air Separation System

Designed to operate under flow and pressure conditions beyond the max parameters of your diesel engine, this patented device filters particulate contaminants and power-robbing air/vapor. Through the positive fuel air separation features of the patented AirDog® II-4G the separated air/vapor is discharged from the filter and back to the fuel tank (through the primary air/vapor discharge port).Excess fuel not needed by the engine during the fuel-cycle is re-captured internally through the pressure regulator back to the water separator.
