The PuriFarr® Modell 400 liquid filter provides superior wear and protection to power assemblies, fuel injectors and other components. Its dual-stage design contains up to four times the media area of conventional single-stage filters for higher efficiency, greater dirt-holding capacity and longer service life.
The Model 400 also features a unique two-piece design for optimum maintenance ease and safety. The filter element breaks down into two sections after use, reducing lifting weight by 50%. Weighing less tha 30lbs. when saturated, used element halves are easy to remove and carry.
The PuriFarr Model 400:
- Filter element splits in two after use for maintenance ease and safety.
- Patented quick-change lid on the filter bowl is easily opened without tools for rapid servicing.
- Has two stages of pleated media to hold eight times more dirt that leading single-stage filters.
- PuriFarr provides a full 92 day service interval to railroads.
- Dual-stage filtration also ensures more complete removal of all size contaminants, reaching efficiencies as high as 99+%.
- Enlarged steel inner core allows the element to operate at very low pressure drop, resulting in longer filter life and more efficient operation.
Engineering studies show that microfine contaminants in the 5-10 micron range are the most damaging to diesel engines. PuriFarr is rated as a 10 micron filter, offering the most effective removal of fine contaminants for maximum engine protection.
