Festool RO 150 FEQ Sander Dust Port Size and Hose Adapter Guide (577017)
The Festool RO 150 FEQ is a 6 inch random orbital sander. It has two modes for fast stock removal and fine finishing, and it is built to run with a dust extractor. Like all sanders, it makes very fine dust that hangs in the air.
The sander has a round dust port on the side. Festool sanders use the 27 mm Plug-it standard, but we have not confirmed the exact port on this exact model. Measure your own port with calipers before you buy. A GulpDust PETG adapter steps the port to the shop vac hose you already own.

Festool RO 150 FEQ Dust Port Size: Round, Festool 27 mm Standard
The dust port on the RO 150 FEQ is round. Festool sanders use the 27 mm Plug-it standard, but we have not confirmed the exact port on this exact model. Measure your own port with calipers before you buy.
Festool builds its tools and hoses around the 27 mm size. Normal shop vacs do not. If you own a Festool extractor with a 27 mm hose, it should plug right in. The trouble starts when you want to use a normal shop vac.
Most shop vac hoses are 1-7/8 inch or 2-1/2 inch. They are way too big for a small Festool port. A GulpDust adapter matches the sander port on one end and your bigger vac hose on the other end, so you get a clean seal.
How to Measure Your Festool RO 150 FEQ Dust Port
Slide the inside jaws of a caliper into the side port and open them out until they touch the inner wall. That gives you the inner diameter. The inner is what the adapter slides into.
Festool sanders are built around 27 mm, so your reading should land near 27 mm. We have not confirmed the size on this exact model, so trust your own number and order the adapter to match.
How to Connect a Shop Vac to the Festool RO 150 FEQ Sander
Clear any dust out of the side port first. A clean port gives the best seal.
Press the small end of the PETG adapter into the port. It is a friction fit, so it holds with a firm push. Then press your shop vac hose onto the wide end of the adapter.
Turn the vac on before you start sanding. Dust collection on a sander is not just about a clean bench. Fine sanding dust is the kind that hangs in the air and gets into your lungs.
Why Dust Collection Matters on a 6 Inch Random Orbital Sander
A 6 inch random orbital sander makes a lot of very fine dust. That dust floats. It does not fall to the floor like saw chips do.
Pulling that dust at the port keeps it out of the air. It also keeps the pad clean, which helps your sandpaper last longer and cut better.
For the smoothest finish, run a steady vac while you sand. A variable speed extractor is nice, but any shop vac with the right adapter does the main job.
Festool 577017 Dust Collection FAQ
What size is the dust port on the Festool RO 150 FEQ?+
The port is round and built on the Festool 27 mm Plug-it standard. We have not confirmed the exact size on this model, so measure your own port with calipers before you buy.
Can I use a non-Festool shop vac with the RO 150 FEQ?+
Yes, with an adapter. Festool hoses are about 27 mm, but most shop vac hoses are much larger. The GulpDust PETG adapter fits the sander port on one end and your vac hose on the other.
Do I need clamps to attach the adapter?+
No. The adapter is a friction fit. You push it into the port and it holds. The vac hose end works the same way.
Why does the RO 150 FEQ need dust collection so much?+
Sanders make very fine dust that floats in the air. That dust is the kind that is bad to breathe. Pulling it at the port keeps the air clean and helps the sandpaper last longer.
Can I print this adapter myself?+
Yes. You can buy the printed PETG part shipped from the US, or download the STL file and print it at home. We suggest PETG with 3 walls and 25 percent infill.
Does the same adapter fit other Festool tools?+
Often yes. Festool builds around the 27 mm port across the line, like the ETS 125 EQ sander and the TS 55 track saw. The OF 1010 router uses an oval port, so it is different. Check each tool page and measure before you buy.
