Tien cutter for dust collection system

Tien cutter for dust collection system

This is a Tien cutter (after the name of the inventor, Phil Thien), whipped up from a 20-liter bucket.
The advantage of the Tien separator is that, unlike a traditional cyclone separator, it does not require significant structural height and will take up very little vertical space. The air in it moves on a flat surface from the edge to the center. It works with the same efficiency as a cyclone separator (if not better), does not take up space, and can be assembled literally from cheap scrap materials in 45-90 minutes.

Circles


Use part of a bucket to draw circles on a piece of wood. You will need three of these circles. One circle will go inside the top of the bucket, another circle will go inside the bottom, and another will go outside the bottom.

Use a router and router compass to cut out the circles. A jigsaw is also suitable for this.

The circle on the left will be placed on the outside of the bottom of the cut out bucket.A groove was cut into it with a router so that it could be placed on the top of another whole 20-liter bucket. The circle on the right will be set inside the top of the bucket.

Collecting dust.
Collecting dust

Lift the cutter and place a bucket under it to collect dust. The weight of the cutter and the pressure of compressed air from the pipe will seal the bucket themselves.
That's all, actually. Your cutter is ready for use. The incredible simplicity and reliability of the design, which you can see for yourself by looking at the process of its assembly, make it an excellent alternative to a conventional cyclone separator.
