High Efficiency Filter Bags – 500 series
The 500 Series filter bag from Allied Filter Systems Ltd contains in excess of 5m2 of materials, and provides a very high oil and dirt holding capacity at high efficiency. It is constructed from 100% meltblown polypropylene microfibre filter media, giving a broad chemical compatibility.
The constituent media has enhanced oil absorbent properties, and coupled with the high surface area, the 500 Series is most commonly used for applications where a high amount of oil absorbance is required. For example, it is widely used in the automotive industry for heavily contaminated electrocoat baths.
The multi layered construction provides an exceptional depth of filter media, around 50mm. The layers of oil absorbent media are separated by drainage layers, ensuring a good flow of liquid and minimising the pressure drop across the filter bag. The outer layers of the filter provide an effective final filtration of the process fluid, retaining very high levels of solids. Particle retention is >95% at the stated micron rating.

The depth of the filter media makes the 500 Series very effective at filtering fluids containing gels or deformable particles.
The 500 Series is manufactured with fully welded seams and our Santaseal ring for optimum performance, or sewn seams with steel or stainless steel ring. It is available rated at 1 – 25 micron in size 1 and size 2 only.

Standard Filter Bags
Allied Filter Systems Ltd 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, consistent high quality and repeatable performance. Filter bags are available in traditional stitched form or with a fully welded construction, and are fitted with a comprehensive choice of rings.
Sewn Needlefelt Filter Bags
Needlefelts are a versatile and cost effective media providing a high solid holding capacity for both non-deformable and deformable, gelatinous particles. By means of a depth filtration mechanism, particles penetrate and are captured throughout the depth of the filter media.
Fully Welded Filter Bags
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 360o hermetic seal between the filter bag and housing, ensuring that fully welded filter bags perform to a higher efficiency than a sewn equivalent.
