Strainer Bags

Menardi manufactures high quality liquid filter bags to fit standard size filter vessels, as well as custom designed products where requested. The constituent materials have been chosen for their purity, ensuring consistent high quality and performance. Filter bags are available in traditional stitched form or with a fully welded construction, and are fitted with a comprehensive choice of rings.

Menardi is a leading manufacturer of fully welded filter bags, which are available for applications requiring standard polypropylene or polyester felts, extended life felts or high efficiency media.

All seams are welded rather than sewn, and combined with either of our positive sealing moulded Welseal (polypropylene or polyester) welded rings, no process liquid can bypass through needle holes caused by the sewing process or around a sewn snap ring. The Welseal ring forms a hermetic seal between the filter bag and housing, eliminating any possibility of bypass around a steel ring, which is a potential source of product contamination. These features ensure that fully welded filter bags perform to a higher efficiency than a sewn equivalent.
