Optrel Swiss Air Replacement Half Mask - Black

Fresh Air, Perfect Fit: Swiss Air Replacement Mask

Let’s be real—after months of sweating under the hood, your respirator mask has seen better days. The Optrel 4160.500 is the factory-original replacement half mask for your Swiss Air system, designed to get your setup feeling brand new again. It’s the exact same comfortable, lightweight black mask that came with your unit, complete with fresh nose foam to keep that seal tight and the bad air out.

Comfort is king when you're welding for eight hours straight. This mask is made from a tough, flame-retardant fabric that won't melt if a stray spark hits it, but it's soft enough to wear all day without digging into your face. Because the Swiss Air system creates positive pressure, you don't have to struggle to breathe—the air is delivered right to you. This replacement part ensures that the airflow stays directed where it needs to be, preventing fogging on your safety glasses or welding lens.

Swapping it out is a breeze. It clips right onto your existing Y-hose and harness setup. If your old mask is getting grimey, stretched out, or just doesn't seal like it used to, this is the fix. It fits seamlessly under any welding helmet—whether you rock an Optrel, a Miller, or a Speedglas—so you never have to compromise on safety or comfort. Keep a spare in your locker so you're never stuck breathing fumes.
