Abstract: The present disclosure relates to pleated filter element comprising: a pleated filter media comprising a major upstream face and a major downstream face and comprising a plurality of oppositely-facing pleats extending between said major upstream face and said major downstream face such that the pleated filter media comprises a first corrugated edge and a second corrugated edge and a first noncorrugated edge and a second noncorrugated edge, wherein the pleated filter media comprises a main pleat section and a first edge pleat section at the first noncorrugated edge, wherein the length of the first edge pleat section is less than 50% of the total length of the pleated filter element between the first noncorrugated edge and the second noncorrugated edge, and/or wherein the maximum pleat height in the first edge pleat section is lower than the maximum pleat height in the main pleat section. The present disclosure further relates to an air filter comprising the pleated filter element in a casing.

Abstract: The present invention relates to a system (40) for air filter management, the system comprising a plurality of air filter devices (41a,b) and an air filter control station (42). Each air filter device (41a,b) is provided at an air filter arrangement in an air flow inlet to an industrial installation and comprises at least one filter medium capable of removing particulate material and/or airborne molecular contamination, AMC, from an air flow received at the air flow inlet. Each air filter device comprises a set of sensors arranged to gather sensor data representative of an operating state of the air filter arrangement, a microprocessor and a communication unit. The air filter control station (42) comprises communication unit arranged to receive operating state information from the plurality of air filter devices and a user interface for selecting an air filter arrangement of an air filter device.
