The filter has a filter chamber, in which a plurality of tubular filter elements and at least one support plate (provided with apertures for receipt of the filter elements) are disposed. A slot between the support plate and each filter element is sealed by disposing at least two seals which have the same diameter as the slot, and engage both the support plate and tubular filter. The seals preferably are flexible in the same way as a piston ring.
