Abstract: A cleaning device for cleaning a filter arrangement which has a first fluid connection, a second fluid connection, and a filter assembly between the first and second fluid connections and which has a surface to which contaminants can adhere. A generator device for generating a gas-fluid mixture includes a receiving chamber for receiving a fluid, and a pressurized gas generating device. A first pipe assembly is connected to the generator device so that the gas-fluid mixture can be provided under pressure into the filter arrangement. A second pipe assembly is connectable to the second fluid connection and a collection device. The collection device collects the gas-fluid mixture and contaminants entrained from the filter arrangement. The first pipe assembly has a deflection pipe section which allows the receiving chamber to be filled with fluid without fluid entering the filter arrangement before the gas-fluid mixture is generated.

Abstract: A method for cleaning a filter arrangement which has a first fluid connector, a second fluid connector and a filter device which is arranged between the first and second fluid connectors and which has a surface to which contaminants can adhere. The method has the following steps: connecting the first fluid connector to a blowing chamber which has a gas connector, at least partially filling the blowing chamber with a liquid, and generating a cleaning pulse, in which gas is conducted under pressure via the gas connector into the blowing chamber for a first time duration, such that a gas-liquid mixture is forced via the first fluid connector through the filter device and out of the second fluid connector.
