    Dust Prevention/Elimination

    The mini-splits remove the humidity fairly well and I have not measured it yet, but I plan to using my SMAN3 to get wet/dry bulb temps.
    What I am planning is installing a Williams Air Sponge as a pressurizing blower to remove the humidity from the outside air and keeping the area a net positive pressure and hopefully dry.
    The Williams is rated 400 CFM @ .6". At this time I am not planning on recirculating the dehumidifier air, but core drilling one 8" hole in the poured concrete block wall for the supply.
    We are located North of Mobile, AL> on the Alabama River and humidity IS a problem with condensing fog nearly every morning.
    We have plenty of cooling, but we need a positive pressure to keep the mill dust out. As a part of the installation we are planning on adding a plenum with filters in addition to the filter supplied with the Williams unit.
    Any observations or experineces to share?


    JDB Zehnder Group is new to the states but has had significant success in Europe in completely eliminating Dust issues in all sorts of commercial/industrial environments. There is no capital outlay and the systems are remarkably affordable.

    How many times must one fix something before it is fixed?
