Venturi™ Designs | Cummins Filtration

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. Fleetguard Venturi Combo lube filters, featuring our patented StrataPore® media and stacked-disc design, remove the smallest dirt particles-which cause the most engine damage-and reduces engine wear by more than 60%, in some cases. The Venturi combination takes lube filtration to a new level of performance, offering key benefits that support extended service intervals (ESI) without compromising engine protection.


By-pass Filtration: Superior by Design
Field testing 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.

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.
