One obstacle every CNC machine user comes across is how to contain the dust produced by cutting materials. Not only is it important to contain dust to keep your workshop clean, but also for your own safety.

The solution? A CNC dust collector. 

In this guide, we review the best dust collector systems for CNC machines, so that you can keep your workshop clean and safe. First, let’s take a closer look at how CNC dust collection systems work and why it’s vital to have one. 

What is a CNC Dust Collector?

A CNC dust collector is a vital component of any workshop as it safely collects dust and debris that is produced by cutting materials like wood, plastics, and soft metals such as aluminum.

If dust from these materials is not safely collected and disposed of, it can cause eye and skin irritation and potentially lead to respiratory problems if breathed in.

There are four main components to a CNC dust collection system 

  • The dust shoe (or boot)
  • The hose
  • The vacuum and filter system
  • The collection bag

The dust shoe attaches to your spindle or gantry and has a curtain made of flexible brush material.

This curtain covers the area immediate to the spindle, containing dust and debris to prevent it from flying outward.

While dust shoes are the more common component, some collectors use dust shrouds, which use a shroud of thin fabric or plastic instead of a brush curtain.

While the brush contains dust, it is sucked up through the vacuum system via the hose.

The dust then travels through a filtration system which collects dust and debris while the dust-free air is expelled out. Finally, the dust is deposited into a plastic bag which you then remove and empty once it’s full.

Further down this guide, we’ll look take a closer look at each of the components you need to consider when making a purchase to ensure you get the right collector for you. 

Before that, though, let’s take a look at the best CNC dust collectors on the market, starting with the most affordable.

WEN 3401 – Cheapest CNC Dust Collector 

Price: $160Available on Amazon here

HP: 1

Wen CNC dust collector

Pros

One of the most affordable dust collectors on the market.

Can move more than 660 cubic feet of air per minute.

12-gallon collection bag.

Wheels for easy transportation.

Cons

No zip on the bag for emptying the dust.

CNC dust collectors generally don’t come cheap, but if you’re after the cheapest and best dust collection system under $200, then the WEN 3401 is one of the most affordable on the market. 

This collector uses a 5.7-amp brushed motor combined with a 6” impeller to move more than 660 cubic feet of air per minute (CFM), which is pretty impressive for such a cheap model. There are four swivel casters that lock in place to keep it stable while in use.

It’s compatible with two dust hoses made by Wen – one measuring 10ft and the other 20ft.

It has a 12-gallon collection bag and measures 34.25”x13”x14” in size, so it’s one of the smaller collectors out there and is a good size for small home workshops.

On top of that, it has wheels and a carry handle for easy transportation, as well as a wall mount if you want to save some floor space.

It’s important to understand that this is a budget machine and it’s not going to provide the same power or usability as a more expensive one, and there are some faults.

For example, some reviewers have pointed out that as there’s no zip on the bag, so you need to empty all the waste out of a four-inch space.

However, for the price, it certainly represents good value and is a decent option if you’re using a low-power hobbyist CNC router.

Jet JCDC-2 – Best Dust Collector for Demanding CNC Work

Price: $2,229.99Available on Amazon here

HP: 2

Jet JCDC-2

Pros

Great for demanding environments with high production rates.

A very advanced CNC dust collection system.

Highly powerful and has constant suction.

Cons

Too expensive and advanced for beginners or casual hobbyists.

The most expensive and powerful CNC dust collector on our list, the Jet JCDC-2 is a 2 HP cyclone collector that is well suited to demanding environments with high production rates. 

As this is a more advanced CNC dust collection system, it has a very large 30-gallon collection drum rather than a standard bag, although you can line the inside of the drum with a bag.

The drum has quick-release levers and independent casters that make it easy to empty and reattach.

The cyclone system used in this collector provides a considerably higher CFM than in single-stage units. It has a highly efficient direct-mount filter that prevents airflow restriction, allowing it to capture 99% of 2-micron particles and smaller debris even below 1-micron. 

This means it captures finer particles than the dust collectors we’ve looked at so far, making it more suitable for working with materials that produce very fine debris and fumes.

Thanks to the high power and constant suction, heavy debris is pulled down into the collection drum before the debris stream reaches the filter, so it’s ideal if you’re making big cuts and there are large chips flying off.

This CNC dust collector also ranks well in terms of usability, as it comes with a remote control that has a range of 50ft and it also has a double-paddle manual cleaning system for easily cleaning the filter.

What to Consider When Buying a CNC Dust Collector

As you will probably have recognized by now, there are a lot of differences from one CNC dust collection system to the next.

Here are the key factors to look at to ensure you settle on the best dust collector for your needs.

Horsepower 

The power of your dust collector, represented by horsepower (HP), determines the speed at which dust is removed.

It typically ranges from 1HP to 2HP. 

Most hobbyist setups will be fine with a 1HP or 1.5HP CNC dust collection system. It ultimately comes down to the power of your CNC machine itself, how demanding your work is, and how much dust your CNC produces per minute.

2HP collectors are typically used in high demanding, professional workshops.

Dust CollectorHorsepower
WEN 34011
Powertec DC5370 1
Vevor 1.5HP Dust Collector1.5
Shop Fox W17271
Jet DC-1100VX-CK1.5
Jet JCDC-22

CFM

Another important factor that’s closely related to the HP of a dust collector is the cubic feet of air removed per minute, represented as CFM.

The more affordable dust collectors typically have a CFM within the 400-500 range, while more powerful collectors can top 800 CFM. 

Bear in mind that if you’re using one dust collector for multiple routers, you’ll need to ensure it can handle the combined CFM required by each router.

Size of Collector 

As you may have gathered from reading our CNC dust collector reviews, they can vary a fair bit in terms of size, so you need to make sure you get one that will fit safely in your workshop. 

If you’re planning on transporting your collector or switching between machines, you may want to prioritize one that’s small enough and has handles to be easily portable.

Another thing to consider is whether your CNC dust collection system comes with a wall mount, as this can help save space in hobbyist setups.

Jet DC-1100VX-CK‎37 x 22.5 x 39 inches
Jet JCDC-2‎26 x 50.66 x 72.25 inches

Filter Size 

The filter size of a CNC dust collector is measured in microns, with one micron being 1/1,000mm. The smaller the filter size, the finer the dust and particles it captures, and the safer the collector is. 

Most affordable CNC dust collectors have 2.5-micron filters or similar, which is absolutely fine for woodworking and most hobbyist projects.

However, if you’re going to be working with materials that emit fumes, such as some metals, you’ll need a much smaller filter size below 1 micron.

FAQs

How much CFM do I need for a dust collector?

For hobbyist setups using a single CNC machine, you need a CNC dust collection system with at least 400 CFM, although most affordable collectors have at least 500 CFM.

If you have a larger setup with multiple machines or are carrying out intense work cutting metal or similar materials, you’ll need a dust collector with at least 800 CFM.

Is 1 micron good for dust collection?

1 micron is usually enough for most hobbyist and small business projects, as it ensures very fine dust and debris measuring up to 1/1,000mm will be caught in the filter.

However, if you’re machining materials like metals that produce harmful fumes, you’ll need a CNC dust collector with smaller filter cartridges, around 0.3 microns.

Is a 1HP dust collector enough?

It depends on your setup, how long you’re running your CNC router or mill for, and the materials you’re working with.

A 1HP dust collector is enough for small, hobbyist setups, but if you’re carrying out more demanding work, you’re best off with a collector with 1.2-1.5HP. Professional setups typically require 2HP.
