xTool O1 Omni to AP2 Air Purifier Slip-On Reducer Adapter

The xTool O1 Omni to SafetyPro AP2 Slip-On Reducer joins your O1 Omni UV printer's exhaust to the intake of the xTool AP2 air purifier in one push. No hose clamp to tighten, no screwdriver, no tape. It slides on, it stays on, and it comes off in seconds when you need to move the purifier or change a filter.

The O1 Omni and the AP2 are made by the same company, and they still don't meet each other directly — the exhaust and the intake are different diameters. This reducer closes that gap with a single tapered transition, so the air your printer pushes out goes into the filter instead of into your room.

Why the connection is the part that matters

UV-curable inks are acrylate-based. The O1 Omni moves that air out the back of the machine, and the AP2 is built to catch it — but only what actually reaches it. Every gap at a joint is a spot where exhaust leaks back into the room you are working in, upstream of the filter you paid for. A purifier is only as good as the fitting in front of it.

A tight slip fit does two jobs at once: it holds the purifier on without hardware, and it removes the leak path a loose or improvised connection leaves behind.

What you get

• Tool-free, slip-on install. Press one end onto the O1 Omni exhaust, press the other onto the AP2 intake. Setup takes under a minute.
• Purpose-built for this pair. Sized for the xTool O1 Omni exhaust and the xTool SafetyPro AP2 intake — not a universal duct reducer you have to shim or tape.
• Smooth tapered transition. A gradual cone between the two diameters instead of a hard step, so airflow isn't choked at the joint and the AP2 can do the work it was designed for.
• Printed in PETG. Holds its shape in warm exhaust air and stays tough where PLA goes brittle over time.
• Removes in seconds. Pull it free to service the AP2 filters or reposition your setup. Nothing to unscrew, nothing to lose.
• Made in Rocklin, California by Clearview Plastics, the shop that builds the O1 Omni enclosure.

Running the O1 Omni inside a Clearview enclosure?

The reducer works the same way with the printer enclosed. Pair it with the xTool O1 Omni UV Printer Fume Control Enclosure to contain ink and cleaning-fluid odor around the whole machine, keep dust off the printheads, and send the exhaust through the AP2.

Venting outdoors instead of filtering? Our exhaust ducting, reducers and elbows take you from the printer to a window.

Frequently asked questions

Does the xTool AP2 work with the O1 Omni?

Yes. xTool lists the O1 Omni as compatible with the SafetyPro AP2 air purifier. This reducer gives you a direct, tool-free connection between the printer's exhaust and the purifier's intake.

Do I need any tools or tape?

No. Both ends are sized for a snug slip fit. Push it on, and it holds.

Will it reduce airflow?

The taper is a gradual cone between the two diameters, not a sharp step, which keeps the transition from becoming a restriction at the joint.

Can I still vent outside instead?

Yes. If you would rather exhaust to a window, use standard ducting from the O1 Omni exhaust. See our exhaust ducting.
