ROLAIR R431 Air Intake Filter Element

This two-pack Rol-Air R431 air intake filter element is a direct replacement for Rol-Air 431-series air cleaners, designed to trap dust, pollen, and other particulates before they reach the compressor pump to help protect the internal components and sustain steady performance. Typically, the filter consists of a pleated-paper element mounted in a rigid metal frame, and installation is straightforward: remove the wing nut secured air cleaner cover and swap in the new element; some listings describe a complete assembly that also includes the rubber intake hose. Because this is a two-pack, you can keep a spare on hand for minimal downtime, and many replacement-part catalogs reference the 431 element across Rol-Air pumps, including models in the K12 through K30 series. By filtering intake air at the source, the R431 filter element helps reduce abrasive wear and clogging, supporting longer service life and consistent airflow in everyday shop and automotive air-compressor applications.
