Guys, we need a challenge - welding respirator

[MeJasonT]

From 69GTO's link, i have found the fan - its 12v and used to cool PC's. Guess what i've bought the fan to play with. I'm still thinking an old cordless drill for the power pack and charger, not using the motor as it will kill the battery in 30 mins of welding. My other attachments should still work with it so lets see how it goes.

Toumas, thanks for your input and suggestions. 3M is my weapon of choice, i have a twin filter face mask already so the plan would be to make the air breather system interchangeable between the 3M mask and the welding mask and use the 3m filters for our fans intake, how does that sound. Already have a 3D model of the filter socket so no need to reinvent the wheel.

Do you have issues with the compressed air systems filters if you take them out of the system when its not in use and keep them in ambient surroundings (eg. an office) to dry naturally and not sit in stale air which obviously causes major health issues.
