MBP Series – High Efficiency Filter Bags
The MBP Series high efficiency filter bags are available rated at 1-25 micron, and perform to efficiencies >95%.
The filter bag consists of up to 4 layers of meltblown polypropylene media, including an outer cover to prevent fibre migration into the filtrate as well as providing added support to the filtration media. The high density of small diameter fibres compared to that of a standard needlefelt enhances particle retention, leading to superior, highly efficient filtration.
Combined with our polypropylene Welseal ring, the MBP Series high efficiency filter bags are available with a fully welded construction, ensuring that no by-pass of process liquid can occur through needle holes. Each layer is individually welded, giving enhanced filter bag integrity and seam strength compared to single weld construction methods.

[wpex more=”Read more” less=”Read less”]Whilst the fully welded versions give optimum performance, sewn versions with a steel or stainless steel ring are also available for universal fitting into all makes of standard size housings, or for custom manufacturing to non- standard sizes.Recently developed is our unique MBPE Series, which features an all polyester construction. This enables high performance filtration at temperatures in excess of 100oc. (e.g. filtration of edible oils or resins). It is also used in applications where polypropylene is unsuitable for chemical compatibility reasons.
MBP and MBPE Series high efficiency filter bags meet EC food contact directives and are constructed from FDA listed materials conforming to code of Federal Regulations 21 CFR Part 177.
MBP and MBPE bags are used in applications previously dominated by expensive cartridge filtration due to higher dirt holding capacities, longer service life and lower overall cost whilst maintaining or increasing the required filtration efficiency. Example applications include protection of membranes in reverse osmosis systems, carbon removal and final filtration of critical fluids. They can also be used as a pre-filter to prolong the life of expensive, sub micron cartridges.
Standard Filter Bag Overview
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.
Sewn Needlefelt Filter Bags
Traditional sewn needlefelt filter bags 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.
