Grizzly Cyclone Dust Collector

Reviewing the G0703 Cyclone Dust CollectorCyclonic dust collectors are a Holy Grail of woodworking. They really do a great job of grabbing dust, and they typically do an equally great job of grabbing space in your shop. The new G0703 Cyclone Dust Collector from Grizzly, $850, has a small footprint; 38-1/4″ long, 23-1/4″ wide, and 65-1/2″ tall. Not bad for a collector that, according to Grizzly, moves up to 866 cubic feet per minute and provides up to 10-1/2″ of static pressure.The G0703 is powered by a 1-1/2-hp motor that’ll run on 110 or 220-volts. The canister filter is made of pleated polyester and includes internal cleaning brushes that help knock the fine dust off the pleats. Large chunks fall into the 30-gallon steel collection drum. The intake port is 6″ diameter.

    I read the article / discussion on dust collectors and after reading the discussions I realized that to most people dust collection is a mysterious topic. Everyone seems to be searching for the “answer” to the dust problem. As a retired professional engineer, I designed hundreds of systems from very small to massive. There is no magic numbers that can be used by a “green-horn” and have a truly workable system.
    First, use the cyclone techology. IF the bigger pieces get into the bag they can tear the bag. Very expensive lesson.
    If multiple machines are connected to the system, without some guidance and calculations (does not require higher level math skills). Blast gates are worth their weight in gold when you are running a larger system. If you have specific questions, send them to WW-goa, and I will try to provide detailed directions so your system will work the way you want it without bteaking the bank in damaged media or a very high utility bill. I did the design work for over 50 years. I am retired and I do not want to do complete designs – it interferes with my making toys and presents for my grandchildren.

    i am a one-man shop and considering a Grizzly G0703 DC. Only one machine will be connected at a time with a 10′ long 4″ flex hose moved to the machine being used. Grizzly recommends a 6″x4″x4″ reducing Y fitting. I will have to blank off the extra 4″ leg. Would not a 6″x4″ concentric reducer work better (less pressure drop)? Having trouble finding a tapered reducer.

      Hi Robert. The gentler the better on the transitions, but I agree that perfect transition pieces are hard to find. I use PVC, and I don’t believe that what you are describing exists in that world. I just accept the imperfection. I think you are probably talking about a very minor difference in air flow, perhaps even measurable, with one such transition. I would suggest checking with Oneida, or a manufacturer of metal ducting, to see if there is a straight 6×4 tapered reducer.
