General Guide

How Does a Dust Collector Work?

Dust collectors are designed with a powerful 1 HP or 1.5 HP motor and a strong impeller fan that creates speeds of 3450 RPM for smaller dust collectors or 6,000 RPM for larger machines. A dust collector is very easy to use. Just attach it to your wood cutting, beveling or wood smoothing tool with a flexible hose and the advanced filtration system will suck the dust out into an attached collection bag. Once the bag is full, you can safely dispose of the dust in the trash.

How do you choose a Dust Collector

To find the right dust collector for your workshop, consider these important features.

Filtration System

Dust collectors are designed with either a single-stage or two-stage filtration system.

Single-Stage Dust Collector

If you have a small workshop or you are a hobby woodworker, a single-stage dust collector is perfect for you. A single-stage dust collector’s filtration system captures dust particles with a size of 2 or 2.5 microns, which is sufficient for most small-medium woodworking tasks.

Two-Stage Dust Collector

A two-stage or cyclonic dust collector is a must-have machine for any DIY woodworking enthusiast or a professional carpenter. Extremely efficient, a two-stage dust collector has improved suction power that can suck up the smallest of dust particles down to 1 micron as well as larger wood chips. This type of dust collector is ideal for medium-to-large woodworking tasks, but it might be too bulky for a small workspace.

Dust Separator

If you already have a wet/dry shop vacuum, you can transform your vacuum into a two-stage dust collector by attaching a dust separator.

Wall Mounted and Mobile Dust Collectors

If your workshop has limited space consider a wall-mounted dust collector. If you are looking for a unit that you can transport easily around your work area, consider a dust collector with a rolling base or a mobile dust extractor.

Cubic feet per minute (CFM)

The airflow speed of a dust collector is measured in cubic feet per minute which is usually between 537 to 800 CFM. To find the right dust collector for your work needs, think about the CFM rating of the power tools that you use on a daily basis. For instance, a bandsaw can create between 300 to 400 CFM and a planer between 500 to 800 CFM.

Dust Collection Bag

A dust collector may have a plastic collection bag or a collection drum. Plastic collection bags are very easy to empty and may also have a viewing window that helps you to monitor the amount of dust inside the bag. Even though a plastic bag is lighter than a collection drum, the bag can break if you overfill it.

Hose/Inlet Port Sizes

You also have to consider the size of the hose or the inlet port that connects the dust collector to your woodworking machine. A dust collector may have a 2 or 4-inch inlet or hose, so make sure that you check the size of the port on your miter or band saw first. You also need to be aware that the hose may or may not come with the dust collector.

Noise Production

The noise production of a dust collector will depend on its suction power and filtration system. Fortunately, most dust collectors produce an acceptable level of noise in the 70 to the 90-decibel range. A more powerful dust collector can still be too noisy in a small workspace, so make sure you invest in ear protection.

Our Verdict

A dust collector, sometimes called a dust extractor, is an indispensable cleaning machine for any woodworking enthusiast. Woodworking tools like a band saw, a miter saw or a belt sander, generate a lot of fine dust that is tough to clean up and hazardous to your health. Whether you work at home or in a professional carpentry shop, a dust collector will help you to work smarter by creating a dust-free workspace that is full of fresh, clean air.
