The Harbor Freight dust collector cyclone upgrade is a game-changer for woodworkers and DIY enthusiasts who want to improve their workshop's air quality and efficiency.
Upgrading the cyclone can significantly increase the dust collector's capacity, allowing you to handle more projects without clogging the machine.
The first step is to choose the right upgrade kit, which can be found in various sizes and configurations, ranging from 2-inch to 4-inch inlets.
A 4-inch inlet upgrade can increase the dust collector's airflow by up to 50%, making it ideal for larger projects.
By upgrading the cyclone, you can also reduce the amount of dust that escapes into the air, creating a cleaner and healthier workspace.
With the right upgrade kit, you can breathe new life into your Harbor Freight dust collector and make it a valuable asset in your workshop.

Upgrading a Dust Collector
You can significantly improve the performance of a Harbor Freight dust collector by making a few simple modifications. One key upgrade is to seal the bottom of the filter, which can be done by attaching two latches to the filter, allowing you to secure and remove a plywood donut and plastic bag.
This upgrade was tested and proved to be effective, resulting in a dust collector that works just as desired and is much quieter than a shop vacuum.
Disassembling and Preparing the Dust Collector
Disassembling the dust collector is a crucial step to upgrade it. You'll need to take apart the motor and fan assembly, the center ring, the hose, and the fittings.
If you're buying a new un-assembled unit, you can skip this step. Most excess parts will go into the scrap pile, but some might be useful for future projects, like the casters, which are often of nice quality.
The center ring has 6 holes in it where the supports bolt on. Simply use the bolts to plug these holes.
Step 1: Dust Collector
The 2hp model from Harbor Freight is a great option for a dust collector on a tight budget. I paid around $165 with tax after using a 20% off coupon.
The filter that comes with this model only filters down to 5 microns, which may not be enough to collect the dust most harmful to your lungs.
Venting your system outside can be a good alternative to spending money on an aftermarket filter. I highly recommend this approach if you're able to.

Steps
To create a chip separator for your Harbor Freight dust collector, you'll need to build a cyclone chip separator. A dust collector is only as good as its filter, and a chip separator can help reduce dust buildup and improve airflow.
Start by gathering materials, including a 5-gallon bucket, some 1/4" MDF, a drill press, and a jigsaw. You'll also need a trash can to collect the debris.
Drill holes in the MDF for the dust collector's hose to fit through, making sure they're centered and evenly spaced. This will allow the dust collector to feed into the cyclone separator.

Cut a slot in the MDF to allow the debris to enter the cyclone separator. The slot should be just big enough for the debris to pass through.
Attach the MDF to the 5-gallon bucket using screws or nails. Make sure it's secure and won't come loose while in use.
