What layflat ducting is for
Layflat lets you put the air where the water is instead of where the machine happens to fit. Under a kitchen cabinet, into a subfloor void, behind a bath, into a wall cavity — all places an air mover cannot physically reach but its airflow can.
It packs flat, which is the other half of the point: a van carrying rigid ducting for every eventuality carries very little else.
Ducting a dehumidifier is different from ducting an air mover
A dehumidifier's output is dry air, and the reason to duct it is to deliver that dry air into a closed cavity or space rather than into the room. Done well, you dry a subfloor or a wall cavity directly. Done badly — with a restricted duct — you reduce the airflow across the coil, which reduces the water the machine removes.
Check the machine is still pulling its expected litres per day after ducting it. If it is not, the duct is too long or too tight.
Two rules that decide whether it works
Keep the run short and the bends gentle. Every metre and every sharp bend costs airflow, and the loss is not linear — a kinked duct can cut delivery to almost nothing while the machine sounds exactly the same.
Match the duct to the machine. Diameter and cuff arrangement differ between air movers and dehumidifiers, and a duct that does not seal at the outlet leaks its air into the room you are standing in.
Care
- Layflat only works on the outlet (blowing) side. On a suction side it collapses.
- Secure it to the outlet and to the area being dried so it cannot blow free and spray air across the room.
- Dry it before rolling it up, and check for splits and pinholes before the next job — a split duct delivers its air at the split.
- Duct used in a Category 3 (contaminated) water loss should be treated as contaminated. It is low-cost and is usually better discarded than cleaned.

Frequently asked questions
Which side of the dehumidifier does it go on?
The dry-air outlet. Layflat collapses under suction, so it is not for the intake.
Will it fit the MaxxDry 85L?
It is listed for the XLGR 125L only. Contact us before using it on another machine.
Razorback parts vary between models and production runs. Tell us the machine and its serial number and we will confirm the part before you order.
