Nothing compares to the efficiency of dust collectors when it comes to dust extraction. No wonder they have become a key component of any woodworker’s shop. To make the best decision regarding your buying needs, it is essential to know the various types of dust collectors and their components. Here are pointers on some common types worth checking out:

dust collectors

1) Unit Collectors

Unit collectors are known to initiate the process of controlling contamination at its source. They are easy to use since they only consist of a fan and a dust collector. Their small size also gives them an edge over the rest by ensuring portability.

Apart from the portability as mentioned above feature, they also come with aplenty benefits such as small space requirements, low initial cost, and the return of collected dust to maintain material flow to mention just a few. Unit collectors are available in two forms – fabric and cyclone collectors. The former is used with manual shaking or pulse jet cleaning. It is normally used for fine dust cleaning. Cyclone collectors, on the other hand, are often used for coarse dust.

Getting the best dust collection system can be a hassle but the unit collectors are a worthy option to help you jumpstart your search in the best way. Perhaps you will not even consider other options as soon as you get your hands on this unit.

2) Inertial Separators

As their name suggests, inertial separators separate dust from gas streams. This is achieved by a combination of forces such as gravitational, inertial, and centrifugal. These forces propel the dust to those areas where the forces exerted by the gas are negligible. The separated dust is then moved into a hopper by gravity for temporary storage.

The three basic types of inertial separators include centrifugal collectors, baffle chambers, and settling chambers. Even though these dust collectors are not often used in the minerals processing industry, their principles of operation remain a critical aspect in the design of high-quality dust collectors.

3) Fabric Filters

Also known as baghouses, fabric collectors utilize the process of filtration to separate dust particles from gases. Over the years, these filters have built an unrivaled reputation as one of the most efficient and cost-effective types of dust collectors with a collecting efficiency of up to 99% for very fine particles.

It also works on a simple process where the dusty gases enter the baghouse before passing through fabric bags acting as filters. The bags can be made from various products such as synthetic fiber, woven or felted cotton, and glass fiber among others.

4) Cartridge Collectors

Unlike the baghouses that use woven or felt bags, cartridge collectors use perforated metal cartridges with pleated, nonwoven media. The pleated design ensures greater filtering surface area than what you would have in a conventional baghouse of a similar diameter.

The greater filtering area implies that these collectors will have reduced air to media ratio, low pressure, and reduced overall size.
