I 3D printed some simple adapters to connect the vac outlet to the 2 stage (primary and secondary) air cleaners in the pic. There is one smaller filter inside the one you see in the pic. These air cleaner elements are from a hydraulic excavator’s engine. They are designed to be free flowing, non restricting, air intake filters.

I screwed carrier to the vac tub to carry the filters while I roll the vac around. It makes a very big reduction in the volume of the vac.

Try it out!

How well does it work? Did you do any sort of measurement?
