Abstract

1. A vertical filter having cleaning means which are directed towards its inner chamber and which are adapted for the removal by blowing of impurities deposited on the filter member, such impurities then being removed from the inner chamber, the cleaning means having a pressure chamber which extends at least substantially over the whole height of the filter member and which is formed with a slot-like air outlet directed towards the filter member, the same being connected to rotating means which rotate the filter member around its axis past the air outlet of the pressure chamber, characterised in that the filter is a bag filter (5) having an unsupported stretched out filter bag (20), and the air outlet (35) of the pressure chamber (30) is sealed off from the environment by means of two resilient strip seals (37) bearing on the filter bag (20), the seals (37) covering a zone (T) of a predetermined minimum width on the periphery of the filter bag (20).
