Harbor Freight Dust Collector - Upgrade Adapter

Dream of upgrading your Central Machinery starter dust collection setup with a higher flowing impeller and larger diameter piping?

Fortunately this topic is well covered and fairly straight forward - except for one thing!

Most people with a shop full of great woodworking tools don't have access to ways to cut steel and form plastics, resulting in a few days spent struggling to make adapters from plywood and PVC to take advantage of the larger impeller.

After upgrading our own setup, we decided we'd use our metal cutting laser and 3D printers to create an easy-to-use kit.

Saves Time & Effort: This Upgrade Adapter turns what would be a multi-day DIY struggle into a simple one-hour job. That’s a huge plus!

Now includes 1/8" x 1/2" replacement foam gasket tape! Use this tape if you tear the existing gasket and as an additional spacer for the tight clearance Wen impeller.

Latest model works with both the WEN and Rikon impellers.

Edit March 19, 2025: We've had to raise the sale price to offset increases from our material suppliers and delivery carrier.
