Extended Service Without Compromise
The Venturi™ Combo's key features support ESI:
- Enhanced gasket and media durability
- Real world contaminant removal
- Real world contaminant capacity
- Low cold-flow restriction
Real World Testing and Performance
Sludge, which occurs when contaminants concentrate in oil, causes extreme engine wear. In the real world outside the laboratory, sludge is an all-too-common enemy. By using real world testing, not simple bench testing, Cummins Filtration has proven that the Venturi™ Combo's by-pass-stacked discs remove harmful sludge and allow the lube system to perform more effectively than full-flow only synthetic filters. In fact, the Venturi™ Combo removes up to three times as many contaminants as full-flow-only synthetic filters.

By-pass Filtration: Superior By Design
Cummins Filtration led the industry by developing by-pass filtration in the 1980s. This technology was quickly adopted as standard by many original equipment manufacturers worldwide. The Venturi™ Combo, featuring our patented
StrataPore™ media and stacked-disc design, removes the smallest dirt particles-which cause the most engine damage-and reduces engine wear by more than 60%, in some cases.

Here's how it works: First, the patented Venturi™ nozzle creates a low-pressure zone to help oil flow efficiently through the stacked-disc section. Then, the nozzle diffuser maximizes the flow through the pleated StrataPore™ media for minimum total-filter restriction.
Why is this better? Because in the real world:
- Cellulose media and current gasket materials are not durable enough for extended service use.
- Low flow restriction is critical to engine protection, especially in cold-start situations.
- Lube filtration systems must have sludge-removal capabilities for extended service use.
- Filter plugging, high-soot engine testing is the best way to measure filter capacity.
Innovative design and thorough testing make Venturi™ Combo the answer for your real world filtration needs.
