The latest generation “UfiCore” air filters by Ufi Filters are now available on the aftermarket. Featuring filtration efficiencies that can reach 99.99 percent, they come in eleven codes that together cover more than 500 different applications
One of the most pressing challenges for designers working in off-road machinery sectors is the need to protect onboard systems of various vehicles—and, of course, their operators—from external contaminants such as dust, moisture, liquids, and gases. This protection is typically achieved either through physical barriers placed where necessary—such as O-rings and seals used to isolate bearings from the external environment and ensure proper lubrication—or through dedicated filtration systems. Examples include cartridges designed to keep hydraulic and lubricating oils clean or those intended to filter the air drawn into engines. The latter is particularly critical, both due to the large fluid volumes involved and the impact that filters have on engine performance and fuel consumption.
To give an idea of the scale, consider a four-liter turbo diesel engine running at 2,200 rpm with a volumetric efficiency between roughly 1.5 and 2.0. Such an engine inhales between six and eight cubic meters of air per minute.
The latest generation of filters
Over an eight-hour shift, this corresponds to air consumption between three and four thousand cubic meters—the equivalent volume of roughly 11 to 15 apartments, each about 100 square meters in size. Essentially, this engine breathes the air contained in an entire apartment block every eight hours, and that air must reach the combustion chambers as clean and contaminant-free as possible. At the same time, this requirement must not negatively impact the engine’s volumetric efficiency, which can happen if air filters are poorly designed or clogged.
Ufi Filters has been studying this problem for years and decided to solve it by offering machine manufacturers an extensive range of air filters—over two thousand aftermarket models—each tailored to meet a specific need. In this context, the latest and most technologically advanced addition is the “UfiCore” off-road filters, already available in more than 500 models grouped into eleven codes. These feature a filter media structure made up of a system of closed and open channels.
A corrugated groove design directs airflow to the filter side of the device, which is closed at the end, causing the air to divert toward the adjacent channel. In this way, clean air reaches the engine’s intake system while minimizing losses in velocity and pressure.
This unique technology allows the filter size to be reduced by up to 40 percent compared to traditional solutions based on pleated filter media. It delivers a declared functional efficiency of approximately 99.99 percent with minimal pressure drop and reduces the overall weight of the unit, making installation easier. All of this is achieved with filter media composed of cellulose and synthetic fibers that are easy to dispose of.
