Claim 6:
7. A method for cleaning off the impurities deposited on a filter element (5) of a fluid filter (18) according to claim 1, the method comprising the steps of:
blocking the fluid inlet (7) and the fluid outlet (8) and holding the compressed air inlet (11) in a closed state, and
opening the fluid outlet (8) and connecting it to the atmosphere and opening the fluid inlet (7) as a dirt outlet (12), subsequently closing the fluid outlet (8) and activating a compressed air flow being present at the compressed air inlet (11) such that it acts on the upper edge (13) of the fluid reservoir (14) which is present in the interior of the fluid filter (18), or
opening the compressed air inlet (11) and connecting it with atmosphere, and opening the fluid inlet (7) as a dirt outlet (12), subsequently activating a compressed air flow at the compressed air inlet (11), wherein the connected compressed air flow is made to act on the upper edge (13) of the fluid reservoir (14) which is present in the interior of the fluid filter (18), or
activating a compressed air flow at the compressed air inlet (11) and opening the fluid inlet (7) as a dirt outlet (12), wherein the connected compressed air flow is made to act on the upper edge (13) of the fluid reservoir (14) which is present in the interior of the fluid filter (18).
