Bag filters, when used in food, beverage or pharmaceutical applications, must conform to EC directives governing plastics in contact with food. Migration limits of contaminants from polymers into a food product have been imposed, and independent testing and certification of component materials is required to ensure these regulations are satisfied. Stringent manufacturing and warehousing conditions as well as special packaging procedures are also required to eliminate other sources of contamination.

Increased thickness of the filter media compared to that of the equivalent standard felt filter bag enables an increased retention of particles. In addition, the extended life filter media has a graded density structure i.e. progressively smaller particles are captured as the fluid follows a tortuous path through the media, stopping the filter bag from blinding prematurely. The result is a filter media with a higher dirt holding capacity, leading to increased filter bag lifetime.

A Filter Bag optimised for your specific application. The NEW “Mega Depth” multi-layered filter bag range has been developed to optimise filtration efficiency, lifetime and dirt holding capacity in either a continuous or batch process. The constituent filter bag layers are customised and selected to meet the needs of your specific application, giving a filter bag which optimises your filtration process.

All seams are welded rather than sewn, and combined with our positive sealing moulded Welseal (polypropylene or polyester) welded ring, no process liquid can bypass through needleholes caused by the sewing process or around a traditional metal ring. The Welseal ring forms a 360^o hermetic seal between the filter bag and housing, ensuring that fully welded filter bags perform to a higher efficiency than a sewn equivalent.
