    Dust collection question

    ok if you have one dust collector hooked up to existing duct work, and get a draw of some degree. if you were to hook another identical motor and impellor setup to the same duct work threw a double wye and exhaust it out threw said bags or directly outside.. would you have more draw at the machines? would it be double the draw or not???

    If you are matching HP to HP I don't think it would make any difference. Only give you more collection capacity.

    I think you'd end up being limited by the capacity of the ductwork - both volume and velocity-wise.

    Might be better to just split the ducting and use different DCs for different tools.

    That's just my guess, though. I have no experiences to back it up.

    Just my 2 cents
    If they both draw 5 cfm than would it not make scents that there would be a 10 cfm draw at the pipe?
    That is as long as the pipe could handle the air volume.
    It could be worse You could be on fire.

    Or would the two DCs somewhat fight with one another?

    that is how i see it chuck i know you cant only draw so much threw a small hole but if i a vacuum sweeper was hooked to it it would be alot less draw than a real dc motor and impeller

    I think they would pull from the path of least resistance.

    I sort of look at it as a stream ( I always think air flow as similar to that of water) if you have two eaqual drops spitting the stream you don't get a bigger flow just less volume. It's a simplistic approch but I think it sounds valid.
