How I improved my dust collection airflow by 18%
A few years ago, I upgraded my workshop dust collection using inexpensive MDF flanges made with my first laser. Since then, I’ve replaced the original blast gates with my automated ball-valve versions, but most of the ducting itself has remained relatively unchanged. The system worked pretty well, but there were still a few areas where I thought it could be improved particularly the amount of flexible hose, some restrictive connections, and how difficult it was to modify the layout. So, I designed a new range of modular, 3D-printed fittings that integrate with my existing flange system and standard PVC pipe. In this video, I break down how the system works, replace some of the more restrictive parts of my ducting, and test whether any of it actually improves the airflow. The final result was an 18% improvement in airflow, along with a system that is much easier to modify, expand and adapt as my workshop changes.
