Abstract

In order to provide an intake system for sucking in combustion air of an internal combustion engine of a piece of equipment, in particular a portable, manually guided piece of equipment, having more than one centrifugal separator comprising a centrifugal separator housing, and having an air filter device comprising an air filter housing, which bounds an air filter receiving space for an air filter, in which the combustion air can be separated by means of the centrifugal separator into a core volume stream and an outer volume stream, wherein the core volume stream is fed to the internal combustion engine through the air filter receiving space, which intake system is as compact as possible and correspondingly designed to be not very component-intensive, it is proposed for the centrifugal separator housing to be arranged on the air filter housing such that it ends directly at the air filter receiving space or projects directly into the air filter receiving space.
