What air cleaner has air travel through two filters before entering the intake piping?

The two-stage cleaner is specifically designed to enhance air filtration efficiency by utilizing two separate filters before the air enters the intake piping of an engine or system. This multi-stage process allows for more thorough removal of particulates and contaminants from the air, which can significantly improve the performance and longevity of the equipment reliant on clean air intake.

In a two-stage configuration, the first filter typically captures larger particles, while the second filter is more finely woven to trap smaller debris and contaminants. This layered approach ensures that the air entering the intake is as clean as possible, which is crucial for maintaining optimal performance and reducing wear on engine components.

While other options such as a single-stage cleaner and centrifugal cleaner are also methods of filtration, they do not offer the same level of filtration efficiency as a two-stage system. A single-stage cleaner only uses one filter, potentially allowing more contaminants to pass through. Centrifugal cleaners operate differently by using centrifugal force to separate dirt from the air but do not employ dual filtration stages like the two-stage cleaner. Therefore, in terms of effective air cleaning for engine performance, the two-stage cleaner is the optimal choice.
