Precleaners are essential to improve the life of air intake filter elements in harsh environments. Precleaners help remove dirt and debris before it gets to the filter element, for longer filter life and fewer element changes.

Reducing the number of filter element changes reduces the risk of dirt entering the air intake ducts during changes, thus resulting in reduced costs and increased uptime.

Our Syklone precleaners are available to suit a variety of engine intake flow rates. Made from very durable polymer material, they are virtually indestructible.

Syklone precleaners are self-cleaning and require no maintenance. Their clever design removes contamination using an impeller rotor driven by airflow, creating a centrifugal force that removes debris through an ejection chute.

Try our single stage precleaner calculator or dual stage precleaner calculator to see how much you could save by incorporating air precleaners into your air filtration system.

To correctly size a precleaner for your air intake system, check out our precleaner sizing wizard or contact our customer support centre for help.


Should you change air filters by miles or hours?

Air filters should be changed only by engine manufacturer's recommendations on air restriction as measured by an air restriction gauge.

Will air filter efficiency change during the filter's life?

Air filter efficiency changes over time. Air filters are least efficient when new; dirt buildup on the outside of the filter makes it more efficient over time.

What is the difference between Cummins Filtration's Magnum and standard line of air filters?

Magnum air filters have more media and more surface area as a result, which extends filter life by providing more dirt holding capacity.

How often should I change my secondary element?

Secondary or inner elements should be changed every third change of the primary element. Secondary filters should not be disturbed until this interval has been reached.

What is Cummins Filtration's recommended air filter change interval?

Cummins Filtration recommends changing the air filter once you have reached 80% of the engine manufacturer's recommendations on air restriction. This ensures minimum downtime during filter change intervals.

Can I use a conventional secondary element with Radial Seal primary filters and vice versa?

No. Once your filter housing has been adapted to use Radial Seal air filters, you must use a radial seal type filter. If your housing has not been adapted for radial seal filters, you must use the standard type filter for proper internal sealing.

What is the micron rating of Cummins Filtration air filters?

Air filters are measured on an efficiency basis over a wide range of particle sizes. Micron ratings do not apply to air filters.
