    Well I am here to pick some brains from the smart people at OSA. I have a miller auto dark hood that would work with their cooling belt system, but for 250 dollars I don’t know if that would be worth it. Anyone used one?
    I am thinking about installing a computer fan and battery in it but I am not that good with electronics. Anyone done this?

    Pretty easy, use a small (2 inch) fan and hang the battery off your belt. Without working the numbers will take a pretty good battery to last any length of time.

    Just a tip for welders if you have boots with the stitching running from the top to the toe you can spray them with clear flex seal and they will last longer sorry wasn’t trying to hijack just passing along a tip

    Even easier get a 40 cm fan and a 9v battery with one of the little clips to connect to it. Most pc fans will run just fine on 9v if just a little slower. If you want something that moves a ton of air get something like https://www.ebay.com/itm/Supermicro...249802?hash=item520ac8cbca:g:ycwAAOSwlzZbDvpp The fans are designed to spin up to around 12k RPM and there are two that are counter rotating. 7 of them fit in a 1U server and can move something like 16 cfm even with head pressure.

    FWIW... I once rigged a 12v motor in an old hair dryer, with the hose run to the top of a clear face shield for when I was in/on my pickup and tractor at the farm (neither was air-conditioned).

    It worked, but blew my eyes full of dust particles. So I suggest ya don't go too high on the airflow volume.

    Just my :twocents: ... :drunk2:

    Keep in mind if you have a fan pulling air into your hood then you run the risk of pulling more contaminates into your breathing zone-3M Speedglas rep here.

    Exactly my first thought upon reading the thread title.
