94801015 - AirPro X4000 Extraction Arm Damper Valve Assembly

Control Your Airflow, Protect Your Lungs

A welding fume extractor is only as good as its ability to capture smoke right at the source. If the damper valve in your extraction arm is broken, loose, or missing, you lose control over that suction. The Upper Arm Valve with Retainer for AirPro X4000 is the direct replacement part you need to get your gear back in working order. When you are welding, you need maximum suction; when you are done, you want to be able to close the valve to stop the noise and save energy for the rest of the shop.

This valve fits into the upper section of your extraction arm, acting as the gatekeeper for the fumes. If your current valve is flopping around or won't stay open, it can restrict airflow, meaning hazardous fumes aren't being pulled away from your breathing zone effectively. Replacing it is a quick maintenance task that makes a huge difference in your daily comfort and safety.

Designed specifically for the AirPro X4000 series (and compatible Nederman arms), this kit comes with the valve and the retainer clip needed to lock it in place. Don't settle for duct tape fixes or arms that don't draw air properly. Swap out the worn valve and ensure that when you flip the hood down and strike an arc, the smoke goes exactly where it's supposed to—away from you.

Key Benefits for the Welder

• Reliable Suction: Ensures the arm stays fully open when you need it.
• Noise Reduction: Allows you to close the arm completely when not welding.
