Dust Collectors and Filters: What They Are and Types

Dust ExtractorA dust collector is a must-have equipment for safety reasons in every surface finishing process. While working, you are prone to breathing toxic debris that poses a health hazard. A collector also helps you to recover your scrap, which you can monetise. But, what do you consider when looking for a collector?

Your Choice of Collector is Critical

You will want to consider the various types of collectors there are in the market. Here are the two main classifications:

Floor-Standing Collectors

These collectors are large and take up a lot of working space. However, the maintenance requirements are low, and the collector handles volumes of work comfortably. You will also spend a little more to buy this type of collector than the table top one.

Tabletop Collectors

Just as the name suggests, these collectors comfortably sit on a tabletop hence taking up less space. They are a cheaper option for collectors especially if you have a less workspace and are handling a small workload.


These are central to the operations of your collector. The floor-standing design is available with bag-type and cartridge filters. The tabletop design is available with drop-in fibreglass filters.

Cartridge Filters vs Bag filters

Bag filters have a large filtration area hence common in large machines. While their efficiency is almost similar to that of cartridge filters, you do not change bag filters as often as the cartridge counterparts. On the other hand, cartridge filters use a new technology hence use up less space. You will need to change the cartridge filters quite often, but the changing process is faster and takes up less time.

Lastly, when choosing your dust collectors, remember to look at the cubic feet per minute rating. A higher CFM rating means your machine will move more dust, fast. You will, however, have to look for a means to handle the loud noise such high CFM collectors produce.
