ABSTRACT:
A filter has a perforated support tube, a tubular corrugated element wrapped around the support tube, two end plates fitted to the opposite ends of the support tube and a fastening band for fastening the opposite ends of the filter element to the support tube. The support tube is divided into a plurality of filtering portions and a plurality of flexible portions. The filtering portions are solidified at their opposite ends by setting resin. Thus, the replacement of the filter element becomes remarkably simple.
