# Shop vacuum Dust collection layout for the garage bench and the tools it serves. - The cyclone bin empties at the driveway door, twice a week. - Replace the final filter each season or the airflow drops noticeably. - The hose is the flexible 4 inch line, never the rigid conduit. - The saw runs on its own circuit so the motor start does not brown out the bench outlets. Airflow is measured at the hood with a cheap gauge; anything under the marker means the cyclone needs emptying before anything else is checked.
