MBP 300 Series High Efficiency Filter Bags
Allied Filter Systems Ltd has developed the MBP 300 Series a unique range of absolute rated filter bags rated from 1 – 10 micron, performing to an efficiency of >99% at the stated micron rating.
For processes requiring absolute filtration, the use of filter cartridges has previously been the method of choice to achieve high performance in critical applications with consumable filter elements.
The MBP 300 Series utilises filter media which enables processes to achieve the same efficiencies using bag filters whilst benefiting from the advantages that a bag filter system has over an equivalent sized cartridge system. These advantages include
- Higher dirt holding capacities
- Higher flow rates (i.e. lower quantity of filter elements required to achieve the same flow rate as an equivalent sized cartridge system)
- Lower initial pressure drops, resulting in longer service life
- Solids are collected inside the bag, rather than on the exterior of a cartridge, leading to easier and quicker filter element disposal and less cleaning of filter housing.
- Ease of handling leading to increased speed of changeout (less process downtime)
- Lower number of sealing points compared with equivalent number of cartridges
- Less storage space required for filter bags compared with necessary number of cartridges.
- Lower disposal cost due to the lower quantity of filter elements required
The result is a high performance filter for the most critical applications which provides a significant reduction in the cost of filtration, without compromise to your process.
The MBP 300 Series filter bags are constructed from up to 5 layers of polypropylene melt blown media, graded to give progressively finer filtration as the process liquid passes through the filter bag. This ensures that the dirt loading of fine particles is distributed effectively within the filter media.
To prolong filter bag lifetime, a coarse melt blown pre-filter layer is present to give a high dirt holding capacity and protection to the finer filtration layers.
All constituent materials conform to EC and FDA requirements for food and pharmaceutical contact applications.
Chemical Compatability Guide
|Media / Collar Type||Acids||Alkali||Solvents||Oxidants||Recommend Maximum Operating Temperature (*C)|

*Flow rate depends on factors such as filter media type, micron rating, and fluid being filtered. All dimensions are nominal.
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.
