Liquid Filter Bags Details:



Needle felt bags give depth filtration in a range of 1 to 200 micron, with 60%-70% efficiency. All felts used in the manufacture of our bags are scrim supported and are heat calendared to eliminate fibre migration.


Mesh filter bags can be manufactured from Nylon, Polyester, and Polypropylene Monofilament mesh, a precision woven thermo fixed structure giving absolute micron ratings with no fibre migration. Micron ratings from 1 to 1500.


Ultrasonically welded seams give 100% integrity, combined with our welded rings, our product gives high efficiency, superior sealing and ease of use whilst remaining cost effective. Welded materials include Polyester, Nylon and Polypropylene felts as well as, Nylon and Polypropylene monofilament meshes.


Tri-star ‘Extended Life’ filter bags are available in Polypropylene and Polyester. The extended life filter media permits an increased retention of particles and therefore the filter bag has a lifetime of up to four times that of an equivalent standard felt filter bag. This feature enables a reduction in purchasing costs and minimizes equipment downtime and engineer exposure. Tri-star ‘Extended Life’ filter bags offer an all welded construction and are available with our custom designed plastic welded sealing rings.


The fully welded multi-layer construction consists of a pre-filter scrim, a micro fibre filter media and an outer layer giving support and eliminating fibre migration.

Tri-star high efficiency filter bags are available in absolute micron ratings of 0.5, 1, 3, 5, 10, 15, 25 and 50 and 100 micron and are manufactured to industry standard sizes.

The oil absorbent property of Tri-star high efficiency bags makes them particularly useful for decontaminating liquids, for example removing silicones and fluorocarbons from e-coat paints.


Tri-star filter bag housings are used in general chemical and processing duties, we offer a versatile range of filter housings starting with the small ‘mini’ series using 4¼” ring bags right through to the industry standard 7″ ring bags in multi pot housings. We offer simple free standing side entry models with Vee clamp closures for economy through to top entry bolted cover designs for maximum security and robustness, the various different designs available will allow you to select exactly the right model for your application, all offer pressure rating up to 10 barg and are electro polished inside and out as standard.
