Blended fuel cycles through
multiple-stage Aquabloc filtration.

The GreenMAX Fuel Filter Water Separator features a patented Direct Injection Fuel Blending (DIFB) Valve. 

This DIFB Valve technology utilizes unused warm engine fuel returning to the tank to provide on-demand fuel heat transfer for cold weather conditions. This cold weather feature allows for direct fuel-to-fuel contact providing instantaneous heat rise. The increase in fuel temperature melts the wax and paraffins that separate from diesel fuel at cold temperatures (cloud point) and restrict fuel flow during the filtration stage. 

The optional DIFB valve is thermostatically controlled to direct engine return fuel into the GreenMAX prior to the filtration stage.

The engine return fuel is mixed with the GreenMAX incoming fuel flow from the fuel tank, providing optimum fuel temperature for efficient fuel filtration and engine performance.

When the fuel system temperature is stabilized for optimum fuel filtration and engine operation, the DIFB valve automatically redirects the engine return fuel to the fuel tank.


















200W in-bowl heater.
 
Gets you started quickly.

To bring fuel quickly to operating temperatures in very cold conditions, optional 
200W in-bowl heater is available. Thermostatically controlled and self-regulating, automatically shutting down once target fuel temperature is achieved.
