Speedglas Welding Helmet Series 9100XXi with the 3M Versaflo V-500E Supplied Air Regulator features Speedglas 9100XXi Air with external grind & memory mode, Speedglas 9100XXi FX Air with flip-up grinding visor and Speedglas 9100 MP with a flip-up grinding visor and safety helmet. Featuring the Speedglas 9100XXi welding auto-darkening lens with True-View technology, the 9100 supplied air helmets allow you to see your welds in greater clarity with colours that appear lighter, brighter and more realistic. An extra-large 73x107mm viewing area and Speedglas SideWindows for improved peripheral vision give you a massive view of your welds and surrounding environment, while unrivalled arc detection reacts down to an industry-leading 1 amp. The Speedglas range of respiratory helmets with the Versaflo V-500E regulator offer excellent protection against carcinogenic welding fume by providing clean, filtered air to the welders breathing zone. A lightweight belt-mounted regulator allows you to adjust the airflow between 170-305 litres per minute for comfortable welding in hot and humid conditions. The filtered air provided offers a Required Minimum Protection Factor (RMPF) of 100+, meaning that it is up to 100 times cleaner than the air that the welder would otherwise be breathing if unprotected. The Speedglas 9100 with supplied air regulators conform to all relevant Australian and New Zealand standards.
