Claim:
1. An air filtration system with vertical construction, in which a suction intake for taking in air contaminated with particles to be separated is provided in the upper region of the system, in which a vertical channel is provided in the interior of the system and contaminated air being taken in is conveyed downward in the interior of the system through said vertical channel, in which the vertical channel features in the lower region of the system a lateral opening, through which the air flow is deflected toward and conveyed through a material pre-separator arranged in the region of the opening, in which a process chamber is provided in the air flow path downstream of the material pre-separator and receives the air flow from the material pre-separator, wherein one or more filter elements is/are arranged in the process chamber, in which a fan for driving the air flow is provided in the air flow path downstream of the process chamber, wherein the material pre-separator has an intake side and an outlet side for a particle-contaminated air flow and consists of several strip-shaped separating elements that are arranged vertically on top of one another, wherein the separating elements are initially arranged from the top toward the bottom with an increasing positive angle relative to the vertical line and at least one lower separating element has a negative angle relative to the vertical line.
