Choosing the Best Fabric Filters


Fabric filters are also known as baghouses. They are commonly used in many industrial applications. Fabric filters have a functioning that is similar to that of vacuum cleaners. Gases with dust pass through fabric bags. When this happens, the particulates get trapped on the fabric surface.

When dust layers are built up of filters at, they are eliminated after high-pressure air is passed through the fabric, or by shaking the fabric.

Dust from the fabric falls to a hopper collection, and this is periodically removed. Accumulated dust is also known as the dust cake. Fabric filters collect dust particles that are sized from a range of submicron to some hundred microns in diameter. The efficiency of this ranges from 99-99.9 percent.

When looking for a fabric filter, you ought to consider the following features.


Fabric filters come in different sizes of fabric filter vessels some are a single length, but others have double length. These have flow rates that differ. The size you chose ought to be determined by the use you are intending to apply the fabric filter in. Your budget too could matters since these are priced differently. If you are not used to fabric filters, functioning, and probably what size will suit you best, it is important to ask an expert in the field. Some stores will also guide you on this. Since most fabric filters have manuals, you will not find it hard identifying a suitable size. Visit this website about filter.


There is four main fabric sewed on dust collector filter socks. These are polyester, polypropylene, Nomex, and nylon. Other fabrics are available for special applications. Mesh and felt material can be used on bags.

If you want a bag that is resistant to chemicals, organic acids, alkalis, mineral acids, and organic solvents, you should consider polypropylene felt bags.


Once you have considered the material, you ought to consider how its construction is. Filter bags have an either sewn or welded construction. Some people opt for sewn constructed filters arguing that its strength is mechanically secure. Once concern about sewn bags is that should the holes be larger than the bag’s micro ratio, the unwanted material might by-pass the filter bag. This becomes a problem in the case when the bag is not properly sewn. Welded construction filter bags do not have any holes, and there are no chances of particles bypassing it. People, however, fear that these bags are not as strong as welded ones.

Finally, consider the micron ratings. This feature should be in line with the use you intend to put the fabric filter in.
