Optrel’s new crystal2.0 e3000 PAPR system consists of a crystal2.0 welding helmet and e3000 PAPR-powered air purifying respirator. The system provides active eye protection, visual clarity and safety against airborne particulates for workers during welding or grinding operations. The NIOSH-approved system protects welders from respiratory particulates including smoke, aerosol and dust. It delivers even air distribution of fresh air within the helmet due to its adjustable air flow control. The helmet’s Crystal Lens Technology (CLT2.0) delivers 31 percent visible light transmission in its light state (protection level 2.0).
