Overview
Phoenix lay-flat ducting, 355 mm (14 inch) × 250 ft roll, 6 mil thickness. Phoenix part number 4024936.
Lay-flat duct is how you get conditioned or scrubbed air from a machine to the place that actually needs it. It ships flat on a roll, you cut the length you need, and the rest stays on the roll for the next job.
What it fits
- Phoenix AirMax — named in the 50 Hz service parts list under Optional Parts as Duct, Lay Flat, 14" × 250'
It suits any machine with a 14 inch outlet — air scrubbers, negative air machines and dehumidifiers. Phoenix also list a 10 inch × 250 ft roll (4024935) for the smaller machines, including the Guardian R. That is not currently a stocked CCW line — ask us if you need it.

Using it well
Keep runs short and straight. Every metre of duct and every bend costs you airflow, and airflow is the whole point of the machine you attached it to. A 30 metre run to save moving a machine 10 metres is a poor trade.
Cut generously at the collar. Leave enough to fold back and clamp properly — duct that pulls off a collar mid-job on a negative air set-up breaks containment, which is a serious problem on a remediation site.
Support long runs. Lay-flat duct inflates and sags. Unsupported, it lies on the floor, kinks, and chokes the airflow you were trying to deliver.
Do not run it through a doorway a door will close on. Obvious, and it happens on every second job.
Cut it, do not save it
Used duct from a fire, sewage or mould job is contaminated. It is a consumable and it costs a fraction of the risk of cross-contaminating the next site. Cut what you need, use it, and dispose of it — the roll exists so that is easy to do.
Clean water losses in a controlled environment are a different judgement, but even then check the inside before you re-use.
Frequently asked questions

250 feet.
What size machines does it suit?
Machines with a 14 inch outlet. The Guardian R and other smaller machines take the 10 inch duct.
Can I re-use it?
On clean water work, sometimes. On contaminated work, no.
Is a duct collar included?
No — collars are machine-specific parts. Tell us your machine and we will check which one you need.
Setting up containment? Tell us the machines and the layout and we will make sure the duct size and collars match.
