About Zipper Ducts
A Zipper-Duct’s Purpose
A zipper duct is a trough with an open top, covered by a conveyor belt that seals the top. A traveling sled is pulled under the belt by a gantry system, such as those found on CNC plasma, laser cutting tables, CNC routing tables, and straight-line welding/finishing applications such as pipe welding. They have also been used in the headhouses of a grain application.
They can be used in any application that requires a straight-line moving sled that provides a moving suction point where milling chips, smoke, or dust is generated.
We can provide Zipper-Ducts equivalent to 5” Diameter/130mm duct, up to 54” diameter/1,370mm duct. We have provided applications with ducts up to 750 Ft/230 meters.

01 How does zipper duct work?
Zipper duct is a fixed trough duct with a rubber-sealed slot along its full length. A slider fitting rides inside the trough and connects to your machine through a short section of flex hose. As the machine travels, the seal opens around the slider and closes behind it, so airflow stays consistent at every point along the run.
02 What can zipper duct extract?
Dust, fumes, and production waste or scrap from machinery that travels a linear path, such as saws, routers, cutting tables, shears, and other sliding or traversing equipment.
03 Why do flex hose and jointed pipe fall short on moving machines?
Over a long travel range, flex hose stretches, kinks, and wears through, which reduces capture velocity and lets dust escape into the work area. Jointed pipe can't follow a moving machine at all. Zipper duct keeps the hose connection short and fixed no matter where the machine is.
04 What seal options are available?
The standard slot is rubber-sealed so the slider moves freely without air loss. A PVC anti-static seal is available where static charge is a concern. Seal and slider materials are matched to your particulate type and operating environment.
05 Is zipper duct an off-the-shelf product?
No. Duct dimensions, seal material, slider configuration, and section length are set by your machine geometry, travel speed, material type, and airflow requirement. Each system is fabricated to your machine's actual stroke length, built from modular bolted sections.
06 What information do you need to size a system?
We'll ask about your machine's stroke length and travel speed, the material being collected, the connection geometry, and the capacity of your dust collector. Systems typically handle 400 to 4,000 CFM depending on material and application.
07 Will it work with our existing dust collection system?
Yes. Our Memphis-area fabrication team integrates zipper duct with your existing collection system.
08 Where is zipper duct made?
Environmental Pneumatics fabricates zipper duct at its facility in Oakland, Tennessee, and supplies it to industrial facilities across the region through a dedicated product line.
Site Evaluation
Start With a Site Evaluation
Most dust and scrap problems are visible to a trained eye. The issue is that most vendors never bother to look. They quote from a desk and ship a catalog product.
Our engineers come to you, walk the floor with you, and tell you exactly what they see.
- On-site visit at your facility
- Dust source, airflow and scrap recovery gap analysis
- Compliance exposure review (OSHA / NFPA / EPA)
- Written summary of findings, with no obligation
