For decades, diesel powertrains held one significant advantage over their petrol counterparts – better fuel economy. In fact, some diesel engines register 20 percent better mileage over petrol, making them the optimal choice for large mobile fleets required to perform heavy-duty hauling and towing.

But improvements in both conventional petrol combustion engines and electric hybrid technologies pose serious threats to diesel’s fuel economy dominance. Complicating matters even further, mandates set by stricter environmental regulations makes diesel even less attractive compared to “cleaner” emissions-free alternatives.

In order to stand out in this new era of markedly improved fuel efficiencies and re-assert itself as the best option for heavy-duty mobile equipment, diesel needs a way to deliver maximized performance at the lowest possible cost. That’s where the new Ultipleat™ Diesel Plus filter from Pall Corporation comes in.

Free water and particulates in diesel fuel are two of the biggest contributors to decreased engine performance, reduced fuel economy, and even complete engine failure. For large mobile fleets, lost production due to downtime is unacceptable, costly, and completely avoidable with the right filtration system.

The Ultipleat™ Diesel Plus filter uses revolutionary technology to carry out two functions normally managed by a dual step process – water removal and particulate control – all within a single filter. The filter elements have a high dirt holding capacity for extensive service life, with industry-leading β5(C)≥1000 particulate removal to optimize filter performance.

Additionally, through the use of a coalescer media layer, the Ultipleat Diesel Plus filter offers true water removal (subsequently drained from the housing) rather than water absorbing media found in other dual element technologies.

The Ultipleat Diesel Plus filter puts diesel back in the game, delivering unmatched engine performance and optimal fuel efficiency. This directly translates into notable cost savings.


We asked a PALL Product Specialist a few questions about the Ultipleat Diesel Plus Fuel filter:

Question: What micron rating of Ulipleat Diesel Plus filters are used?

Answer: 5um @ ß≤1000 however we are looking at expanding the range to all standard Pall M&E filter grades (3, 7, 12, 22)

Question: What kind of Diesel fuel is compatible with Ultipleat Diesel Plus?

Answer: All types of diesel fuel up to B20 bio-diesels have been shown in lab testing to be compatible and have similar performance with the Ultipleat Diesel product.

Question: What is the recommended changeout differential pressure for the Ultipleat Diesel Plus element?

Answer: 35psi ≈ 2.4bar is Pall’s recommended change out differential pressure for Ultipleat Diesel Plus elements however terminal differential pressure for the element is 50psi ≈ 3.4bar

Question: What is the clean differential pressure across the element?

Answer: Clean differential pressure across the element is approximately 0.05bard/kL/min ≈ 0.0027 psid/USgpm

Question: With the higher water effluent ppm in certain fuels, will this affect the onstream life of the filters at all?

Answer: No, as the water is not held by the element, Ultipleat Diesel Plus elements contain a coalesce media layer between the media pack hence separating the water from the fuel instead of the conventional method of adsorbing the water from fuel which can lead to lower element life when challenged with high water ingress.

Question: Will a Ultipleat Diesel Plus element fit into a Ultipleat Diesel housing and vice versa?

Answer: An Ultipleat Diesel Plus element will fit into a Ultipleat Diesel housing but due to the lack of a separator the water will not collect away from the fuel hence free water will still be present in the fuel downstream of the element. Ultipleat Diesel elements will fit into a Ultipleat Diesel Plus housing but due to the lack of coalescing ability no water removing capabilities will be achieved.

Question: What happens to the water after it is removed from the fuel?

Answer: After the free water is separated from the fuel it collects in the bottom of the vessel to be drained off.

Question: How large is the water collection area of the vessel?

Answer: The water collection area also known as the sump area is approximately 10% of the overall vessel volume which is shown on the datasheet.
