21710 - ESAB Air Filter Regulator 7-120 PSI

Clean Air for Superior Cuts

Every welder knows that moisture is the enemy of a good plasma cut. The ESAB 21710 Air Pressure Regulator with Filter is your first line of defense against wet, dirty air that kills consumables and ruins workpieces. Designed to fit ESAB plasma cutting systems and other pneumatic tools, this essential accessory ensures that the air reaching your torch is clean, dry, and at the perfect pressure. With an adjustable range of 7 to 120 PSI, you can dial in the exact settings needed for everything from gouging to fine-detail cutting.

Why You Need This Regulator

Using raw shop air without proper filtration is a recipe for disaster. Water in your line causes the plasma arc to sputter, creating rough edges and dross buildup that requires hours of grinding to fix. Worse, it eats away at your electrodes and nozzles, forcing you to spend money on replacements far more often than necessary. The ESAB 21710 solves this by trapping moisture and debris in its integrated filter bowl, delivering only purified air to your machine. It’s a small investment that pays for itself by extending the life of your consumables and improving the quality of every cut you make.

Built for the Shop

This isn't a flimsy hobbyist part; it's an ESAB-quality component built to withstand the rigors of a working shop. The easy-to-read gauge lets you monitor pressure at a glance, and the adjustment knob is designed for precise control. Whether you are replacing a worn-out regulator on your PowerCut machine or upgrading your air supply setup, the ESAB 21710 gives you the control and protection you need to keep welding and cutting without interruption.
