CleanAir CA-20 Welding Helmet with Breathing System

Welding helmet CA-20 represents the combination of high level optical quality 1/1/1/1 and the highest class of respiratory protection TH3.

This innovative welding helmet brings a solution for integrated air distribution allowing the possibility to adjust the airflow direction and at the same time ensures the maximum level of welder´s protection, making it the best choice for use in the heaviest industrial environments. The CA-20 welding helmets are equipped with auto-darkening filters (Balder Grand) which use the revolutionary technology of Angular Dependence Compensation ADC Plus.

Areas of application
Professional welding hood suitable for all welding methods including TIG, even with very low welding currents.
