Abstract
A candle type precoated filter for residual volume filtration has a pressure vessel having a cylindrical upper part and a conical base, a plurality of filter elements arranged substantially vertically and including at least one residual filter element and other filter elements formed so that the at least one residual filter element is lengthened toward the base and is longer than the other filter elements and a separating wall which separates the residual filter element in an upper portion of the pressure vessel from the other filter elements so as to be tight against media and to project out in a lower portion of the pressure vessel beyond a length of the other filter element.
