Beschreibung
Zusammenfassung:	A filter includes a pleated filter material with a plurality of pleats arranged circumferentially. The pleated filter material includes a top half and a bottom half. An end cap is coupled with an axial end of the pleated filter material bottom half, and at least a portion of the pleated filter material is tapered. With a smaller end cap, the filter has less area on which dust can accumulate. L'invention concerne un filtre comprenant un matériau de filtre plissé avec une pluralité de plis agencés sur une circonférence. Le matériau de filtre plissé comprend une moitié supérieure et une moitié inférieure. Un capuchon d'extrémité est couplé à une extrémité axiale de la moitié inférieure du matériau de filtre plissé, et au moins une partie du matériau de filtre plissé est conique. Avec un capuchon d'extrémité plus petit, la surface de filtre sur laquelle peut s'accumuler la poussière est moindre.
