Dust Filter Socks Multipocket Bags Sleeves

R&B Industrial manufacture and supply a large range of dust and liquid non-woven filter bags.


Many popular bags are held in stock ready for next day delivery. For instance multipocket bags for DCE Unimasters, Airmaster, DCS, Spencer Halstead. Filter socks for DCE Dalamatics, Mikropul, Heaton Green, DISA, Nederman, etc. 

We manufacture filter bags from a range of different media, for a range of different applications. We will happily advise you on which media/finish is best suited to your particular application.

We can manufacture bespoke filters for a particular application or dust collector.

We can also supply bags in various specialised membranes and surface treatments. Please contact us for you specific requirements.

In filtration, non-woven fabrics can be generally described as a random fibrous web, having an interconnecting open area throughout the cross-section and able to remove a percentage of particulate from liquid or gaseous fluids streams flowing through it


Typically, non-woven fabric manufacturers supply filtration media having from 1 to 500 micron mean flow pore (MFP) ratings. Below 10-15 micron, the fabrics must be calendered in order to achieve the finer micron ratings. There are a number of different calendered finishes available dependant upon specific process requirements.

Micron ratings depend significantly on the test procedure by which the manufacturer rates the media and whether the rating is liquid or air. As ratings vary widely from one manufacturer to another, users must be extra careful when comparing media from one supplier to that of another. Huge variations can and usually do exist. Therefore, it is particularly important to ask the non-woven manufacturer for a copy of the test procedure used to rate their media.

In addition to the micron pore rating, there are a number of other considerations including dirt holding capacity, flow rates and differential pressure data to name a few.


Non-woven fabrics have been manufactured, in multiple forms, from many grades of cellulose and most natural and synthetic fibers at one time or another. The most popular fibers used being polyester, polypropylene and glass. Following are acrylics, rayon, nylon, cotton, fluoropolymers and a host of others that fill niche applications because of their special material compatibility for particular applications. Most people associate glass fibers with air and synthetics with liquid filtration, but there are plenty of exceptions, especially with synthetics in the form of melt blown non-woven fabrics that are increasing popular in air filtration.

Nonwoven fabrics have thicker cross-sections and bulk compared to membranes, wire cloth and monofilament fabrics. Thus, nonwovens fabrics are the material of choice when large quantities of particulate loading, long-life or where general clarification of a liquid or gas stream is required. Non-woven fabrics are relatively inexpensive compared to most other media.


We also have in stock a large range of filter cages and multi-pocket bag inserts.
