Does a cyclone increase CFM?
Cyclones are two-stage machines. They're much more efficient than single-stage collectors, and have two significant advantages: Cyclones can generate higher CFM and overcome greater static pressure loss.
Do I need a cyclone with my dust collector?
Cyclone dust collectors frequently serve as pre-filter systems which reduce the dust loading to downstream baghouse and cartridge dust collectors. A cyclone pre-cleaner can save wear and tear on the filters and cleaning systems, thus reducing the associated maintenance and servicing costs of the dust collectors.
What is a 2 stage dust collector?
A two-stage dust collector consists of a first stage cyclone, a blower and a second stage after filter. A cyclone separator is a cone shaped vessel into which the dust-laden air enters. The dust particles' inertia causes them to move toward the separators outer wall.
How do you increase the CFM of a dust collector?
Clean your filters often! When the lower bags in a two- or four-bag chip collector fill up, the unit's filter area is effectively cut in half. This not only reduces suction significantly, but the higher air pressure inside the bag also forces fine dust particles through the fabric and into the shop air.
What is a good static pressure for dust collector?
In most cases you can use 6” for a baghouse and 5” for a cartridge collector. Then add 1” If an outlet duct exists in the system. Fourth, add the friction loss in the duct system coming to the dust collector. For simple runs of 100' or less, you can use 6” as a rule of thumb.
Do I need a cyclone dust collector?
Cyclone dust collectors frequently serve as pre-filter systems which reduce the dust loading to downstream baghouse and cartridge dust collectors. A cyclone pre-cleaner can save wear and tear on the filters and cleaning systems, thus reducing the associated maintenance and servicing costs of the dust collectors.
How many CFM does a portable dust collector need?
If you have a 10” table saw with a CFM need of 350 CFM and a horizontal belt edge sander with a CFM need of 550, then you’ll need a dust collector capable of handling a minimum of 550 CFM.
What is the maximum CFM needed for a dust collector?

Why do you need to collect dust from sawdust?
When you’re working with wood, any kind of sawing or cutting will create excess wood chips, sawdust, and release an unbelievable amount of dust particle into the air. Why does it matter? Firstly, you want to ensure a safe working environment. Sawdust and wood chips underfoot aren’t exactly safe. Couple unsure footing with blades spinning fast enough to saw oak beams, and you’ve got a no-brainer reason why you need dust collection.
How does a dust deputy work?
They work by adding an additional collection area between the end of your hose and the canister of your shop vac. The design of these pieces create a vortex of air which causes more dust and debris to be captured. In my experience, these units work ok. However, I feel like they are rather expensive and bulky to only get “ok” results. By the time you get all the parts you need, you are already into it $100. Personally, I’d rather put that money towards a dust collector or air filtration system.
How much does a two stage dust collector cost?
For one of these units you can expect to pay anywhere from $200 on up to several hundred if you need a very powerful setup.
Why do you need a dust collector?
Inhaling fine dust is the cause of severe respiratory issues, allergies, and can even shorten your life. It might sound drastic, but it’s true.
Can a single stage dust collector pull dust?
Single-stage dust collectors will pull chips and shavings, but won’t do a good job of filtering out the small airborne particles. To solve this issue, you can add a separator and an after-market filter to your machine, ensuring a system that won’t clog but will filter out lung-harming particles from the air.
Identifying Your Dust Collector Needs
The type of dust, particulate matter, and gases being generated within the facility will play a significant role in determining what kind of dust collector system works best for your facility and its size.
Choosing the Right-Sized System
The size of the facility and the type of dust, gases, and particulates generated will play a big part in the selection process. Once those dust collector needs have been identified, three primary factors will determine the correct size of the dust collector.

Get to know about CFM first. Your dust collector shall be work properly if the value of the CFM is the least.
What Size Dust Collector Do I Need? Make Your Choice
If the size of the dust collector is not proper according to the place, it is very harmful. For example, if you work in a mill or a factory and there is a dust collector in a small size. But there is a lot of dust everywhere, and little dust collector does not collect the dust properly.
What Size Dust Collector Should You Choose? A Final Word
So, the choice of a dust collector entirely depends on your requirements. Whether you need it for your home or shop, just make the right choice by keeping in mind the specifications of the product.
The Right Volume
The most important consideration to factor into a new dust collector is making sure the airflow or volume of the dust collector is efficient at capturing dust and is right for your application.
Measurement of Volume
You measure volume in cubic feet per minute or otherwise known as CFM. CFM is a measurement of airflow related to air conditioning, heating and ventilation environments. In dust collector applications CFM measures the amount of air per minute that can be moved from a space.
How fast does air move through a woodshop?
For systems carrying woodshop dust and chips, engineers recommend minimum air velocity of 4,000 FPM in branch lines (that’s about a 45 mph breeze) and 3,500 FPM in the main duct. The speed of the air moving in the system may exceed these figures, but shouldn’t fall below them. Maintaining the velocity at or above the minimum value ensures that dust and chips will remain in suspension as the air flows through the system.
