Abstract: A filter bag assembly includes a filter media fabricated from synthetic materials, has a heat sealed edge forming a cylinder, with one end of the cylinder being heat sealed (welded) to form a closed container. The other cylinder end is folded over a relatively rigid ring member and is sewn (stitched) in a manner to affix the ring member to the filter media thereby maintaining the integrity of the media's micron rating.

Abstract: A filter bag with removable ring and handle suitable for use with high pressure filter housings includes a two-piece ring which is assembled together with a filter bag without the need for stitching or welding and includes a handle as an integral part of one of the rings to facilitate removal of the filter bag from a filter housing.A method of assembling a filter bag with a removable ring and handle for removal of the filter from a filter housing is disclosed.

Abstract: A high pressure liquid filter vessel fabricated of non-metallic materials and used for the filtering of liquid in a permanent installation provides for a simplified method of replacing the filter bag and includes a removable cover which displaces a relatively large volume of liquid. Removal of the cover from the filter housing reduces the liquid level within the housing to a level below the lip of the filter bag, making it easier to grab the lip thereof, and remove the bag without coming into contact with the liquid being filtered. The bracket used for retaining the cover on the filter housing prevents distortion thereof and makes the filter ideally suitable for high pressure filter applications where corrosive liquids are involved.
