Dust Collection System Buying Guide

Dust Collection System Buying Guide

Imagine inhaling a cloud of sawdust, metal shavings, or concrete dust—not a pleasant thought, right? Unfortunately, this reality faces many individuals in various workplaces and hobbies. Dust, seemingly harmless, poses significant health risks, including allergies, respiratory irritation, and even chronic illnesses. Thankfully, dust collection systems offer a powerful solution, capturing these harmful particles and creating a cleaner, healthier environment. This guide will help you understand what a dust collector is, why you need one, and how to choose the right one for your needs.


The Crucial Role of Dust Collection

Long-term exposure to dust can lead to a variety of health problems, from minor to serious. For instance, wood dust has been classified as a human carcinogen that can cause allergies, skin conditions, and respiratory illnesses like asthma and lung disease. Metal dust, meanwhile, can lead to metal fume fever, a flu-like condition with symptoms such as chills, fever, and muscle ache.


Dust collection systems capture these harmful particles before they reach your lungs. They typically consist of a fan that draws dust-laden air through a filter, trapping the dust and returning clean air to the environment.


Beyond health, a dust collection system offers several other benefits. It can extend the life of your tools and machinery by preventing dust buildup, which can hinder performance and cause wear and tear. It can also make your workspace safer by reducing the risk of dust explosions, a serious concern in industries that work with combustible dust.


Types Of Dust Collection Systems

Now, let's delve into the diverse world of dust collectors and explore the options available:

1. Canister dust collectors

Canister dust collector

Canister dust collectors feature a cylindrical canister-shaped filter cartridge that captures dust as the air flows through the device. The dusty air enters the collector where it passes through the filter cartridge, causing the dust particles to stick to the outer surface of the cartridge. Clean air is then expelled from the collector, while the accumulated dust is regularly removed from the cartridge by cleaning or replacement.


Canister dust collectors offer high filtration efficiency and capture fine dust particles down to 1 micron in size. Cleaning or replacing the filter cartridge in a canister dust collector is relatively simple and straightforward. These systems can be pricier upfront, especially if they come with advanced features like variable speed control and remote operation. 


Compared to larger systems, such as baghouse collectors, they have a lower capacity for storing dust and in environments with high static electricity, dust can accumulate on the filter cartridge. This reduces airflow and efficiency and requires regular cleaning to maintain performance.

2. Bag dust collectors

Bag dust collector

Bag dust collectors use fabric bags to capture dust particles. As air is forced through the bag, dust particles get trapped in the fabric while clean air passes through.


Bag collectors are generally less expensive than other types, suitable for a wide range of particle sizes. Bags may need to be replaced regularly, and cleaning can be labor-intensive. They may not filter out very fine dust particles effectively.


3. Dust separator

Dust Separator

Cyclonic Dust Collectors use the principle of cyclonic separation to remove dust from the air. The air is spun at high speed, creating a vortex. The centrifugal force drives the larger dust particles outward, where they fall into a collection drum. The remaining clean air, along with any remaining fine dust, is then passed through a filter before being expelled.


These systems can filter out even very fine dust particles and require less maintenance than other types, but they are also generally the most expensive option. 


4. Shop vacuums

Shop Vacuums

Shop Vacs, while not technically dust collectors, are often used in smaller workshops for dust collection. They use a motor to create suction and a filter to remove particles from the air.


They can handle both dust and larger debris.The shop vacs are easy to move around the workshop as needed. However, they are not suitable for large quantities of dust. Smaller collection containers require more frequent emptying as the filters can quickly become clogged with a lot of dust.


5. Hanging dust collectors

Hanging Dust Collectos

Hanging dust collectors are generally compact devices that are designed to be suspended from the ceiling or mounted overhead if space is limited. They usually have a motorized impeller, a filter mechanism and a collection container or bag.


Hanging dust collectors are ideal for applications where floor space is limited or where mobility is required, such as woodworking shops, auto repair shops and small manufacturing plants. As they require installation and may not be suitable for handling large volumes of dust due to their compact size.


Key Features to Consider In Your Dust Collector


MERV rating: Higher ratings capture finer dust. Dust collectors typically utilize MERV 12 filters, while Purisystems sets the standard higher with the PuriCare 1100. This system employs a dual filtration approach: a 5-micron filter for larger particles, and a 1-micron filter for the finest dust, making it an excellent choice for both woodworking and metalworking applications.

Size & capacity

CFM: Don't overspend! Match CFM to your workspace and dust generation volume (check manufacturer charts or online calculators). 

Noise level

Noise-sensitive environments: Prioritize quieter models (<75 dB) with sound-dampening features or variable fan speeds. 


Frequent movement: Wheels and lightweight design are key. Consider size and feature trade-offs for portability. 


Accessibility: Accessible filters and easy cleaning save time. Look for self-cleaning features or removable dust containers. 


Assessing Your Dust Collection Needs

Before diving into specific models, evaluate your specific needs:

Room Size: A larger room will require a more powerful system with higher airflow (CFM) capacity.
    Amount of Dust:Consider the volume of dust generated and how frequently. Heavy dust generation demands a larger capacity system.
      Type of Dust: Dust generated by different activities varies significantly. Woodworking creates larger, fibrous particles, while cutting and wire sawing might produce finer, denser dust depending on the material. Shredding can involve both wood and paper dust, requiring adaptable filtration. Purisystems dust collectors are ideal for wood carving, sanding, turning, scroll saw work, rotary tools, powder mixing, and more.
        Frequency of Use: Occasional use allows for a simpler system, while frequent use necessitates a more robust and durable option.
