Industrial Ductwork for Dust Collection Systems
Your duct, from Nordfab Quick-Fit: clamp-together pipe and fittings, priced by the part in our store.
Why it matters
Your collector only performs as well as the duct feeding it
Your duct connects every pickup point, hood, and capture arm to the collector. Undersized duct chokes your airflow. Oversized duct drops transport velocity and lets material settle in the run. A poor layout wastes static pressure and shows up on your power bill.
If that sounds familiar, it is rarely your doing. Duct often gets sold as a pile of parts with no sizing behind it. Every system we design includes the full duct design: branch sizing, transport velocities, static pressure calculations, and a complete bill of materials. We sell Nordfab Quick-Fit and size it to your system.
Why clamp-together? Welded or flanged duct takes days to hang and is hard to change later. Clamp-together duct goes up in about half the time with no welding, no rivets, and no special tools, and you can take it apart and move it when your layout changes.
The duct we sell
Nordfab Quick-Fit
Your duct comes from Nordfab, the company that originated clamp-together ductwork. Quick-Fit uses a rolled lip, an over-center clamp, and a gasket at every joint, and all pipe is laser welded. Above 24 inches, Nordfab builds flanged duct with angle rings.
What you get
About 900 items stocked in the Nordfab Now program, with a full range of fittings, branches, elbows, adapters, hoods, blast gates, and diverter valves. Galvanized steel, 304 stainless, and 316 stainless. Made in Thomasville, NC.
Where it fits best
Dust collection systems from 3 to 24 inches, jobs that need 3D layout files (NordCAD and Revit families), and oil mist runs using the QFS sealed version.
When it is not the right duct
Runs over 24 inches, highly abrasive material, and jobs that call for airtight duct need something else. Tell us and we will point you to it.

Ductwork components
What goes into a complete duct system
Straight Pipe
Five-foot lengths with a rolled lip on both ends. Your gauge depends on your dust and the transport velocity your run needs.
Elbows & Branches
30°, 45°, 60°, and 90° elbows. Lateral, Y, double, and T branches for systems with more than one pickup point.
Blast Gates & Valves
Manual and automatic blast gates, butterfly valves, and diverter valves to control airflow at each pickup point.
Hoods & Transitions
Canopy, barrel, and slotted hoods, plus rectangular-to-round transitions that connect your machines to the duct.
Adapters & Reducers
Hose adapters, machine adapters, reducers, and flange adapters to tie into the equipment you already have.
Adjustable Sleeves
Telescoping sleeves so you do not have to measure to the inch. Slide to length, clamp, done.
Hangers & Supports
Wire rope hangers, pipe hangers, clamp hangers, and strut hangers to support your run, plus roof and wall flashing where the duct leaves the building.
Safety Accessories
Spark traps, explosion isolation valves, silencers, vibration dampeners, and no-loss stackheads.
Design
Why your duct design matters more than the duct itself
You can buy good clamp-together duct and still end up with a system that does not pull. Most dust collection problems start in the duct layout, not at the collector.
Every branch, elbow, and transition adds resistance. Every pickup point needs its own airflow and transport velocity to carry dust without settling. Miss the balance and you get plugged duct, weak capture at the machine, and a collector that cannot keep up. If the collector itself is the question, compare our industrial dust collectors.
With our design process you get a duct layout with calculated branch sizes, transport velocities matched to your dust, static pressure loss through every fitting, a full bill of materials, and an installation drawing.
If your dust is combustible, which covers most industrial dust, your duct is part of your dust hazard analysis under NFPA 660. Transport velocity, bonding and grounding, and isolation all apply to the duct run, not only the collector.
What does it run? See our 2026 cost guide. On most systems we quote, duct materials run roughly 15 to 35% of the equipment price. Large projects with long runs and many pickup points can go higher, and a collector that sits close to your machines keeps it lower. Installation is priced separately by your installer.
Questions
What buyers ask about duct
What is clamp-together ductwork and why is it used for dust collection?
Clamp-together duct has a rolled lip on each end of the pipe and fitting. A gasketed over-center clamp closes around the two lips, so there is no welding, riveting, or bolting. It goes up in about half the time of flanged duct, and you can take it apart and move it when your layout changes. Nordfab Quick-Fit covers 3 to 24 inch diameters. Above 24 inches, Nordfab builds flanged duct with angle rings.
How much does ductwork cost for a dust collection system?
On most systems we quote, duct materials run roughly 15 to 35% of the equipment price. Large projects with long runs and many pickup points can go higher, and a collector that sits close to your machines keeps it lower. Your number depends on pickup points, run length, diameters, fittings, material, and gauge. Installation is priced separately by your installer.
Does ductwork need to be part of a dust hazard analysis?
Yes. Under NFPA 660, the duct in a combustible dust system is part of the dust hazard analysis. Transport velocity has to stay high enough that dust does not settle in the run, duct sections need to be bonded and grounded, and isolation between the collector and your building may be required. The dust hazard analysis is completed by the owner or a qualified third party.
Can you use clamp-together duct for oil mist or food plants?
Standard Quick-Fit is built for negative-pressure dust collection and is not sold as airtight. For oil mist, Nordfab QFS adds sealed seams and double gaskets. For food plants, stainless Quick-Fit with ePTFE seals is the usual setup.
How fast does Quick-Fit ship?
Nordfab Now keeps about 900 items on the shelf that can ship as soon as the next business day. Plan on 1 to 2 weeks from the day you order from us.
