Abstract
A filter element has a pleated filter mat (). The terminal axial ends () of the mat are connected to end caps (). The mat has a main structural layer () having filtering properties and a first additional structural layer and a second additional structural layer (). The surface area of each of the additional structural layers () is smaller than the surface area of the main structural layer (). The axial ends () of one additional structural layer () is located at an axial distance from the axial ends () of the other additional structural layer () on the filter mat ().
