Abstract
A filter arrangement for backflushable filtration as well as a filter candle are formed in such a way that dead spaces and screw connections that are difficult to subject to backflushing are avoided, especially in the non-filtrate space (6). The filter candles (7) are held by a head portion (13). The head portion (13) is pressed against a holder arrangement (3) by means of tensioning means (9) arranged in the filtrate space (6). A support element (10) connects the head portion (13) with the tensioning means (9), said tensioning means (9) being able to bear against a contact surface (11) of the support element (10). The filtered liquid is led from the inside of the filter candle (7) through a flow-through channel (22) between the outside surface (20) of the support element (10) and the inside surface (21) of the opening (4) in the holder arrangement (3) into the filtrate space (5).
