Abstract

A filter candle, especially for gas equipment, includes a plurality of cooperatively associated tubular mutually telescopically engageable filter-candle segments. Each segment is comprised of an inherently dimensionally stable material. Each segment has structure for supporting each segment relative to the other segments, and additional structure for limiting the movement thereof relative to the associated segment. Structure is also provided for releaseably supporting the segments together as a filter candle.
