Abstract

A method for extracting process air loaded with overspray from a coating plant, which includes leading overspray picked up by an air stream as process air along a flow path to a conditioning device. The process air is led on the flow path through at least one replaceable flow module having an inlet opening and an outlet opening, on the inner surfaces of which overspray can be deposited and, after a limiting loading with overspray has been reached, can be replaced by an unloaded flow module. An apparatus for extracting process air loaded with overspray having at least one replaceable flow module having an inlet and an outlet opening arranged in the flow path of the process air. On the inner surfaces of the flow module, overspray can be deposited. The flow module can be replaced with an unloaded flow module after a limiting loading with overspray is reached.
