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.
High Efficiency Filter Bag Brochure
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.

Allipure Series – High Efficiency Filter Bags
Allied Filter Systems Ltd has developed the Allipure series, a unique range of absolute rated filter bags rated from 5 to 0.6 micron, which perform to an efficiency of 99.98% (Beta 5000) at the stated micron rating. For processes requiring absolute and/or sub micron liquid process filtration, the use of filter cartridges has previously been the method of choice to achieve high performance in critical applications with consumable filter elements.
Extended Life Filter Bags
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.
Filter Bag Accessories
Allied Filter Systems Ltd is able to supply a wide range of bag filter accessories to complement our range of filter housings and also those from other manufacturers. Restrainer baskets – Stainless steel 316L in all industry standard sizes and available in a variety of styles to fit all types of housings. Baskets can also be manufactured with a stainless steel mesh lining (37 to 840 micron) or produced from perforated sheet other than the standard 3mm, commonly 1mm to 10mm. Coated baskets (e.g. Halar) are also available.
