You might think that all you need to do is call them up, tell them your model number and you will be set. But is it really that easy? Can you always rely on just any supplier to get you the right bags, at the best price, every time?
Outlined below are several things that will help you to find the right supplier for your next set of replacement baghouse filters. Going into the filter quoting process armed with this information will enable you to secure the products at a fair price. These are the three key points to keep in mind when searching for your next set of replacement bags.
Have The Correct Information Before You Call
Most people begin their search for replacement bags with only the most basic of information, if any at all. At times all they have is some supplier’s arbitrary product number from their last set of bags, or a serial number from the side of their baghouse. The fact is that there is no central database of baghouse filters out there for your supplier to check. The majority of these product numbers are from their respective manufacturers and only for their internal record keeping/branding.

While you may not have easy access to all of this information when sourcing quotes, the more you have the easier it will be for the supplier to give you an accurate quote. Information to have on hand includes:
Dust Collector Type – What kind of filters, cleaning system type, etc.
Filter Measurements – Physical dimensions of the filters
Filter Construction – This differs based on how the bags are installed in the baghouse
- Top (Snapband, Strap, Raw Edge, etc.)
- Bottom (Snapband, Disk, Compression, etc.)
Filter Fabric – The material along with any coatings, finishes or membranes
- Fabric (Polyester, PPS, Cotton, Fiberglass, etc.)
- Coating/Finish (Singed, fire-resistant, etc.)
- Membrane (PTFE, etc.)
Special Considerations – Special added features needed only on certain bags
- Antistatic wires
- Support rings

This would include air temperature, product to be filtered, alkali or acidic level, combustibility of the dust, etc. You should also including information about how often you replace your filters, system pressure drop, filtering efficiency. While not absolutely necessary, this information will allow a good supplier to offer suggestions for different products that might improve the operation of your system. (SEE BELOW)

How to Choose a Baghouse Filter Supplier
There are hundreds of filter suppliers, manufacturers, and sales reps out there to choose from. Finding one that will get you the best product and provide you with the best service for a fair price is no easy task.
Often times, companies portray themselves as “dust collection experts” when in reality they are only sales reps that have little real knowledge of how these complex industrial systems operate. You will want to consider their level of experience in the industry. Companies with real-world experience in the field are able to provide a vastly superior service than the rest. For example, an experienced supplier will be able to not only take your order, but also offer suggestions on how to improve your dust collector operation by offering tips on installation methods, maintenance procedures, and other ways to increase system efficiency, and extend bag life. They also will be able to offer suggestions for different products (such as new fabrics, pleated elements vs. traditional bags, etc.) that could reduce costs and increase efficiency.
Additionally, you should look into the reliability and trust-worthiness of the company before doing any business with them. This can include asking for references from their previous clients, reviewing their return policy, and any guarantees they may offer on their products.
