Dust collection ductwork
Ductwork is the pipe and hose that carries dust from your tools to your collector. Three things decide how well it works. What you make it from, how the turns and branches are shaped, and whether the joints leak.
Most shops get the machine right and lose half of it in the run. Air slows down at every sharp corner, and every open joint bleeds suction off the whole system, not just the branch it sits on. So the layout matters as much as the collector does.
We do not sell pipe. We print the parts that join it: the reducers, the fittings, the hose adapters, and the tool adapters at the far end. The guides below are the planning side, and the parts below that are the joining side.
Plan the run
Six guides on what to build a duct run out of and how to shape it.
PVC or metal, which should you run?
What each one is good at, why 4 in. pipe is not 4 inches across, and whether to glue or screw the joints.
Elbows and branches, why shape matters
One 90 or two 45s, what elbow radius to use, and why a gentle branch keeps more of your air moving.
CFM and static pressure, plain English
Why diameter changes suction more than almost anything else, and where the airflow in a run actually goes.
Blast gates, and where to put them
Why gates leak when they are closed, why they jam with dust, and how many branches you can leave open.
Does PVC duct need grounding?
The loudest argument in any shop. Builders who ground, an electrician with a meter who doubts it, and what nobody has settled.
Floor sweeps on the run
A pickup at floor level so the pile by the saw goes into the duct instead of a dustpan.
Join the run
Pipe comes in a handful of trade sizes and your tools do not. These are the parts that bridge the gap. Each one is printed to order in PETG, made in the USA.
Size guide
Every hose and port size in one chart. Start here if you are unsure.
Fittings
Elbows, couplings, and caps, printed to the sizes you give us.
Reducers
Step one duct size to another. The same part reduces or expands.
Hose adapters
Join flex hose to smooth duct so the joint holds.
Tool adapters
The last connection. Your duct to the port on the tool.
Connectors and gates
Bolt-on port flanges, quick-connect clamps, and blast gates.
Want duct from us too?
We are looking at carrying rigid duct and flex hose so the whole run comes from one place. It is not here yet. Tell us what your shop needs and we will email you if it lands.
