AIR FILTER CARTRIDGE FOR I.C. MOTORS, METHOD FOR ITS MANUFACTURE AND AIR FILTER INCORPORATING SAID CARTRIDGE

摘要

Air filter cartridge for I.C. motors, including a body in which there are defined, in the flow direction of the air to be filtered, an upstream face and a downstream face of the cartridge, wherein the body includes at least one pair of panels of filtering material provided in a substantially V-shaped arrangement, so that at least one channel for the passage of air is define between the panels of the at least one pair of panels, wherein the filtering material of at least one of the panels includes a corrugated sheet of filtering material, wherein, on opposite surfaces thereof, a succession of corrugations and grooves are defined. The invention further concerns the method of manufacturing the cartridge as well as a filter equipped with the cartridge.

1. An air filter cartridge for I.C. motors, comprising a body having a parallelepipedal or cubic shape in which there are defined, in the flow direction of the air to be filtered, an upstream face and a downstream face of the cartridge, said body comprising at least a pair of panels of filtering material provided in a substantially V-shaped arrangement, so that at least one channel for the passage of air is defined between the panels of said at least one pair of panels, wherein the filtering material of at least one of the panels comprises a corrugated sheet of filtering material in which, on opposite surfaces thereof, a succession of corrugations and grooves are defined mutually parallel and parallel to said upstream face and said downstream face of the cartridge, and wherein at least two of the corrugations have mutually different height.
