The Adflo 9100xxi FX air fed welding respirator covers all bases with it's large true-view lens, FX grinding headtop, super comfy headband & long life PAPR blower unit. The Adflo PAPR unit is designed to provide welders with a constant air flow rate of 170 litres per minute regardless of the battery's charge or the particle loading of the filter. It's difficult to argue with it's lightweight lithium-ion battery, fast switching between welding & grinding & instant on mode. It has all the pedigree a blue chip manufacturer such as 3M has to offer and has the high NPF(nominal protection factor) of 500. It is also classified as TH3.
A suitable alternative is the Foster Industrial Prem-Air welding respirator. The Prem-Air PAPR blower unit boasts smart sensor technology, offering constant airflow regardless of filter condition and a user interface which displays battery capacity, air flow level, filter status & temperature. P3 filtration is supplied, as standard.
'True-view' is an innovation that offers the welder enhanced vision around the work place when welding. A clearer view of the job when the lens is in it's light state offers a further benefit. This means you don't need to lift the headtop to inspect your work.
The bluechip version of 'Trueview' comes in the form of 3M's Speedglas 9100xxi, which not only incorporates 'True-view', but a number of other defining features such as an external button to facilitate quicker switching between welding & grinding and the ability to programme two preset modes. If you're a spectacle wearer and you can MIG, plasma cut and TIG weld to very low amps to your heart's content..
Giving the Speedglas 9100xxi a run for it's money is the Miller Digital Infinity. With a deeper helmet shell, the Infinity is a great choice for heavy duty MIG welding and it has the largest welding filter lens on the market to boot. The recent introduction of it's information centre, in the form of Info track, allows the operator to record arc time. A multi language help menu is a great addition too
