If you already own an ESAB A50 Sentinel welding helmet and want to convert it into a Sentinel A50 for air, then this is the kit for you.
The kit is made up of 3 parts:
1. Sentinel A50 for air shell & head gear including air duct
2. Sentinel face seal
3. Esab EPR-X1 Air backpack
You would need to swap the lenses and ADF unit from your existing sentinel helmet to the new kit here, which would then create the Sentinel A50 for air headtop helmet.
