Multi Layer Felt Filter Bags
Multi Layer felt filter bags provide graded density, multi stage depth filtration in a single filter bag. A high dirt loading capacity and superior filter bag lifetime is achieved by selecting the optimum micron ratings of the pre-filtration and final filtration layers in accordance with the needs of the filtration process.
Multi Layer filter bags can be produced with 2 or 3 layers of polypropylene or polyester needlefelt, and to further enhance performance, a layer of extended life felt can be incorporated. An optional mesh exterior cover can also be provided.

Allipure Series – High Efficiency Filter Bags
Read moreAllied 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
Read moreIncreased 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.
