FILTER ASSEMBLY WITH PLEATED MEDIA V-PACKS, AND METHODS
摘要
<p>A generally cylindrical filter element incorporating nonsymmetrical or asymmetrical V-pleated media. The V-pleated media provides increased filter media per given filter volume, extended filter life, and a smaller filter for equivalent filter life. A smaller filter is generally beneficial for some applications such as aircraft, due to its lower weight. Various features of the filter include asymmetric variable pleat heights applied to a cylindrical or obround filter; defined pleat spacing applied to a variable pleat height element; optimal pleat density; and optimal shape of inlet and outlet.</p>
