Thread: New Workshop, now I need new dust collection

  1. #16
    Since this is a business... Insurance... Liability... Workmans comp....

    Make sure you have a big dust collector... Perhaps call up your insurance carrier and have a talk with them... Many commercial and industrial insurers have engineers onsite to help with stuff like this...

    You may want to think about some sort of fire prevention (or at least automatic shutdown) as well... Say a fellow works some abrasive material and it sparks off the saw... Not uncommon with stuff like Ipe... Or sharpens chisels on the belt sander... You really don't want a dust collector fire...

    And with the likelihood of such... You may want to think about putting the dust collector out in a place where if there's a fire - it's at least away from your shop.. You lose the dust collector - but not your business..

    Seriously?.....wow....I wasn't expecting that....
    I can speak directly to that and to the two models of Grizzly you first mention. I am a one man shop that does pieces on commission. I generally do less than half a dozen large pieces per year so balance that against the amount of spoil your shop creates. Given that comparison . . .

    I really wanted to get the 3HP G0441. I made the regrettable mistake of being lazy and not wanting to modify some structure in the shop to make it fit. I bought the 2HP G0440. It has been a great machine and has been fired up almost daily for 9 years now. I'd certainly say I got my money out of it based on the price at that time.

    Dust collection with the 2HP unit has always been adequate but, not great. I still have to sweep up now and again and enhance my collection with two Dust Deputy equipped shop vacs and an ambient cleaner. The usefulness of an ambient cleaner is another discussion and collecting the dust at the source is your goal. At any rate I have always chastised myself for not putting out the effort for the 3HP. The way prices are today I would probably just go ahead and step up to a 5HP.

    Bear in mind I do no production work of any kind. This is one man shop making custom stuff that moves at a snails pace compared to a production shop.

    Read this page. Work backwards from the tools. Layout the shop on paper, figure out where you want the tools, do the math for the dust needs of the tools, design the ductwork size based on location and tool requirements making note of perf needs, then decide on a collector that can deliver the needed performance in that design.

    Hi Mike, your link has good information except that their CFM requirements are far too low for adequate fine dust collection, the CFM requirements I saw listed were in line with chip requirement specifications.

    My saw requires 480 CFM at the base, plus over blade collection to meet 2mg/cubic metre requirement............Regards, Rod.

    Jim's advice is spot on.

    Where I live a professional Engineer would have to design and test the system after installation to verify that it meets applicable safety and fire codes.

    This isn't a trivial issue for a business as you have legal liability for health and safety issues................Regards, Rod.
