  • Polishing Room Dust collection

    Hi so in my new shop we are building a polishing room but need a dust collecter that actually works. In my friends old shop he was using a grizzly and it was emitting all of the garbage back into the air. I am also doing powder coating in this shop obviously in a completely separate room but I need a dust collector that works very good. The room itself is about 18x18 or so so lets oversize it a bit and say 20x20. Any help would be greatly appreciated. Thanks

    all you say is that you are using a grizzly , but grizzly makes many different type of dust collectors also you do not say what are you mainly using in your polishing room are you working on a work bench or are you using larger stand alone polishers also can you extract air out of building or does it have to recirculate in the room
    how many people working at the same time and is the room used once in a while or is it used full time . there are lots of factors to consider when trying to set up a dust collector system. and one more thing to consider when using a dust collector is the filter capacity , a 1 micron filter will be more efficient than a 3 micron filter but will have more restriction and will clog up faster .

      It wasn't my dust collector it was at a friends shop so im not sure of what type it was. We have two stands each side has a 5hp motor. Big industrial 3 phase machines. We need something that can recirculate the air obviously thats why i mentioned it needs to emit nothing back into the air because my shop needs to be extremely clean especially for powder coating.

        i had a similar set up , 3 x 3 hp 3 phase buffers plus 2 large work bench to do the sanding all in a 14 x18 closed room , this room was in my powdercoating shop .
        the only way that i managed to keep most of the dust out of the shop was to have asystem that exausts the air to the exterior of the building .
        i had a 18 inch explosion proof fan with 18 inch ducts sucking the air and dust out of the room and at the other end of the room i had a 20 x 20 inch filtered opening taking air in from the rest of the shop creating a draft of air coming in and taking the dust out . with the fan working i always had a negative air pressure inside the polishing room keeping the dust from going into the other section of the building.
        you could probably use a system that will recirculate the air inside but it will need at least a three stage filtering similar to the powdercoating booth we use .
        such a system uses pre filters 4 x 24 inch by 24 inch followed by 4 multi pocket filters and then final filters the last ones should be of the hepa type filters if you want to be close to zero dust in the air. but if you do full time polishing like i was even a system like that will not be perfect and you will have to replace those filters very often, the cost of the pre filters is not much but the pocket filters are about 35 $ a piece and the hepa filters if i remember are about 75 each.
