3m Air Fed Mask

[Allen1988]

Hi All,

Can’t see my I find an answer in this.

We have a air fed mask by 3m for our 2k spraying in the workshop, this has a twin filter at the screw compressor end and a triple filter and regulator at the outlet end, currently this is only used for painting however the adapter that goes on your belt fits the 3m air fed speedflas I use for welding, I’ve put it on the mask and it seems much better output then the backpack with filter.

My question is, does anyone use the compressed air feed to fill there welding helmet as opposed to the filtered backpack?

I have definitely seen a handful of workplaces that use a supplied air setup for welding hoods, but it comes with its own set of advantages and disadvantages.

Mostly it's the need to be aware of and protect the air-hose which can make it awkward, something that's much easier in a more structured workshop or production cell, than an environment where you are on/in/under the workpieces... But the low profile of the air supplied system makes things a lot easier when you're crawling into tight spaces and under stuff.

I've arranged for compressed air to feed welding helmets in confined spaces where the backpacks are just not compact enough. Otherwise i don't see the point. Much easier to have a batter back pack and not be connected to a cable.

You can get an air fed pipe for standard 3m 6000 series masks.
I use them when I'm welding in tight spaces.

If you are feeling flush you could look at the Optrel Swiss Air system, I'm sure they will have a air fed option.
