| Category | Nordfab QF Advantage | What Standard Ductwork Does | Why It Matters |
|---|---|---|---|
| Construction & Seam Quality | |||
| Laser-Welded Seam | ✓ Full-length laser-welded longitudinal seam no gaps, no lockform ridges, no leakage paths along the pipe body | Spiral and standard clamp ductwork uses lockform seams mechanically formed, not welded; seams are a known leakage and weak point under vacuum | A leaking duct system means the fan is moving air that never reaches the hood, capture velocity at the machine drops, dust escapes into the breathing zone, and the collector runs harder than needed |
| Vacuum Rating | ✓ All QF pipe and components third-party tested to 80″ W.G. collapse resistance — 22ga for 3–12″, 20ga for 13–29″, 18ga for 30″ and above | Standard HVAC ductwork (24–26ga) is not rated for industrial dust collection vacuum, and can collapse un the static pressure. | Filters load over time and static pressure rises; duct that is not vacuum-rated for the fan's shut-off pressure will collapse. Third-party tested collapse ratings give engineers documented proof the duct will hold |
| Heavy Gauge Options | ✓ Available in 18, 16, 14, 12, and 10 gauge and flanged ends up to 72″ diameter for abrasive, high-velocity, or large-volume applications | Some ducting systems offer only standard gauge, abrasive dust wears through light gauge elbows and straight runs rapidly | Silica, glass fiber, heavy wood chips, and metallic dust act as sandblast media at conveying velocities; 14-gauge elbows at wear points extend service life significantly and reduce replacement frequency |
| Installation Speed & Flexibility | |||
| Tool-Free Assembly | ✓ Single lever clamp no rivets, screws, bolts, welding, or special tools required; telescoping sleeve eliminates exact-to-the-inch measurements during installation | Flanged ductwork requires drilling, bolting, and sealing every joint skilled trades required, measurements must be precise, mistakes require cutting new sections | Nordfab cuts installation time by more quite a lot compared to flanged ductwork, a direct reduction in installation labor cost on every project, and a faster path from equipment delivery to production startup |
| 100% Reusable | ✓ Every QF component unclamps, relocates, and reinstalls without damage. Machine moves, layout changes, and production line reconfigurations reuse existing ductwork | Welded or riveted ductwork is destroyed during removal, machine relocation means buying entirely new duct runs | Indiana manufacturers reconfigure production lines regularly; Nordfab QF ducting is a long-term capital asset rather than a consumable — the duct moves with the machine rather than being scrapped |
| Clog Access | ✓ Remove two clamps, pull any section, clear the blockage, reinstall — under two minutes without tools or confined space entry | Fixed ductwork requires cutting out a section to access a clog, then welding or flanging a replacement piece back in, hours of downtime per event | Conveying applications with heavy or sticky material clog regularly; QF access eliminates the extended downtime and hot work permitting that fixed duct systems require for the same maintenance task |
| Sealing & Air Tightness | |||
| Gasketed Clamp Joint | ✓ Standard nitrile gasket in every clamp — silicone and ePTFE options for high-temperature applications; die-formed rolled edges ensure uniform metal-to-metal contact at every joint | Spiral duct with slip-fit connections has no gasket — joints rely on friction and sealant application, which degrades over time and requires periodic resealing | An ungasketed joint in a negative-pressure dust collection system draws in ambient air — dilutes the airstream, reduces capture velocity at hoods, and allows fugitive dust to escape at the joint |
| QFS Sealed System | ✓ QFS sealed ducting line — additional sealing for oil mist, cutting fluid, and applications where standard QF leakage rates are not acceptable | Standard clamp ductwork is not rated for sealed oil mist service — coolant mist leaks through joints, creates slip hazards, and contaminates equipment below the duct run | CNC machining centers with coolant mist collection require sealed ductwork above work areas and walkways; QFS provides the additional joint integrity needed without switching to a completely different duct system |
| Materials & Special Applications | |||
| Stainless Steel Option | ✓ 304 and 316 stainless steel QF ductwork — same clamp-together system in corrosion-resistant construction for food, pharmaceutical, and chemical applications | Galvanized steel corrodes in wash-down environments, acidic exhausts, and high-humidity applications — requires replacement or costly interior coating | Food processing and pharmaceutical facilities require wash-down compatible ductwork that meets sanitary standards; 316SS QF components provide corrosion resistance with the same fast-install benefit as standard galvanized |
| NFPA Conductivity | ✓ Metal-to-metal contact at every rolled-edge clamp joint ensures electrical continuity throughout the system — grounding lugs available for additional static dissipation requirements | Gasketed or plastic-component duct systems interrupt electrical continuity — static charge builds up on isolated sections, creating ignition risk in combustible dust environments | NFPA 660 requires electrical continuity in ductwork handling combustible dust; Nordfab's conductive joint design satisfies this requirement at every connection without additional grounding straps or bonding wire |
| Design Tools & Support | |||
| 3D Design Software | ✓ Quick-Fit Visual 3D duct design software and Revit families for BIM projects — design the complete system, generate a parts list, and export drawings before ordering a single piece | Standard duct suppliers provide catalog pages only — system design requires a separate engineering engagement or manual takeoff from paper drawings | 3D design eliminates field measurement errors and change orders; the parts list generated by Quick-Fit Visual is the purchase order — no guessing on quantities, no over-ordering to cover mistakes |
| ISO Certification | ✓ ISO 9001:2015 and ISO 14001:2015 certified manufacturing — Nordfab Americas produced in Thomasville, NC; largest manufacturer of clamp-together ducting in the world | Many duct fabricators are regional shops without ISO certification — quality and dimensional consistency varies between production runs | ISO certification ensures every QF component from any Nordfab plant fits every other QF component, dimensional consistency is guaranteed, not assumed; critical for facilities that source replacement parts years after original installation |

Frequently Asked Questions
Nordfab is a global manufacturer of industrial ductwork and the largest producer of clamp-together ducting in the world. Their Quick-Fit (QF) system uses a modular single-lever clamp connection instead of traditional bolted flanges or welded joints.
Sections lock together with a single clamp, reducing installation time by more than 45% compared to flanged ductwork. The system is available in galvanized steel, 304 stainless steel, and 316 stainless steel, in diameters from 3 to 72 inches.
Nordfab Quick-Fit ductwork installs more than 45% faster than traditional flanged ductwork. The single-lever clamp connection eliminates drilling, bolting, welding, and sealant application at every joint. Nordfab
No skilled trades required for the connection itself, and the telescoping sleeve eliminates exact-to-the-inch field measurements. For facilities that reconfigure production lines periodically, the system also disassembles and reassembles quickly, every component is 100% reusable without damage.
QFS is Nordfab's sealed duct system designed specifically for oil mist and cutting fluid applications. Standard ductwork can leak coolant fluid at joints over time, creating slip hazards and contaminating equipment below the duct run.
QFS uses enhanced gaskets and sealed connections that prevent fluid migration, making it the appropriate choice for CNC machining centers and any process where oil mist or liquid coolant enters the duct stream.
Yes. Standard Nordfab Quick-Fit uses full-length laser-welded longitudinal seams and gasketed clamp connections that produce leak-free joints rated to 80 inches W.G. collapse resistance.
The QFS Sealed system provides additional liquid-tight performance for oil mist and cutting fluid environments. Leaky ductwork is one of the most common causes of underperforming dust collection systems, Nordfab eliminates that variable at both the seam and the joint.
Nordfab Quick-Fit is available in galvanized steel for standard dust and fume applications, 304 stainless steel for corrosive or food-grade environments, and 316 stainless steel for the most demanding chemical and pharmaceutical wash-down applications. Heavy gauge options (18, 16, 14, 12, and 10 gauge) are available for abrasive dust service.
We specify the appropriate material and gauge based on your dust type, conveying velocity, process chemistry, and applicable safety standards.
Yes — this is one of Nordfab's most significant advantages for Indiana manufacturers. Every QF component unclamps, relocates, and reinstalls without damage.
Machine moves, production line reconfigurations, and facility expansions reuse existing ductwork rather than requiring new purchases. Nordfab QF ducting is a long-term capital asset rather than a consumable, the duct moves with the machine rather than being scrapped.
Yes. Nordfab provides Quick-Fit Visual 3D duct design software, Revit families for BIM projects, AutoCAD resources, and CSI-formatted duct specifications.
