Making a particle filter that doesn't wear out for my plasma cutter

Summary by Krater

The creator designs, builds, and tests a custom S-shaped vortex separator filter for their plasma cutter down draft system. Testing shows the filter successfully captures metal dust without significantly restricting airflow.

Answers: How do you build a DIY cyclonic dust separator filter for a plasma cutter downdraft table?

• plasma cutter down draft system
• cyclonic dust separator design
• particle separation geometry
• DIY workshop air filtration
• anemometer air speed measurement

What it concludes

• An S-shaped channel design forces heavy particles to hit the wall and drop out of the air stream without requiring filter media.
• The S-shaped filter design reduces dust passing through the exhaust to less than 5 percent compared to running without a filter.
• Running the plasma cutter with the S-shaped filter installed does not noticeably reduce airflow or machine performance.
