Topic tags/keywords: grizzly cyclone g0703 super dust deputy g0443 cyclone dust collector

I was looking for some insight from what other woodworkers have experienced with 1.5 and 2 HP rated cyclones. I have read most users state to go for bigger HP however I am looking for the balance point of efficiency and size that will fit my current and slightly larger future workspace.

I currently have a small woodshop/garage 12×24 and have a 1.5HP single stage dust collector and am looking to upgrade it to a cyclone or do a super dust deputy Frankenstein collector. For the price I located the grizzly G0703 shipped $900 + I would add the 220 volt option which would save my time from any modification.

The specs on this appear to be slightly rated low. I think with a 6 inch pipe it may actually have a better CFM than the 775 listed which I believe is with 5 inch pipe. It has a 13.5” impeller which would allow it to be very efficient and it pulls 18.8 amps on 110 volts for 6 inch piping and 9.4 amps on 220 volt with 6 inch piping. The other grizzly 1.5HP cyclone G0443 states the same motor amp specs but has a smaller 12.5” impeller and states a 1,025cfm rating which doesn’t make sense to me that it could be rated higher with a smaller impeller and same motor specs?

The G0703 will work perfectly for my shop now, do you think it would work with 15 to 20 foot 6 inch pipe runs when I eventually move to a bigger shop and is the CFM rating closer to that of the G0443 when ran with 6 inch piping?

Thanks for any thoughts or input,

I am also researching cyclones for my small shop (16×30). I haven’t yet purchased but I think I will be going with the G0443 over the G0703 due to a couple factors:
—The 220v conversion kit for the G0703 is $250.00 but the 220v kit for the G0443 is under $100.00 (the numbers blew me away when I checked with Grizzly). When the kits are added in, the price of the two systems are nearly identical.
—The G0443 has better performance for the buck. I think this is due to cyclone design. The G0443 uses an air ramp and larger filter. But the G0703 doesn’t seem to be using an air ramp, which can have significant impact on efficiency (it also has smaller filter area). I dug through the online manuals for each system & found their fan performance curve charts – when comparing it is obvious that the G0443 will move significantly more air across the static pressure range.

Of course the advantage of using the G0703 would be portability – the G0443 must remain anchored to the wall and connected to a duct system. But I have an ideal corner for it and I can keep my ducting short with few turns.

Before I purchase the G0443 I would be glad to see if anyone else has experience with it.

Idaho Grizzly lists the 220v conversion kit for the G0703 for $100 which is what I paid for mine. Where are you hearing it cost $250?

That said guys I cleaned out my G0703 cyclone for the first time yesterday, I was impressed by the fine dust that collected in the drum, there is maybe a cup of material in the plastic bag. I love how portable it is, not just moving it from machine to machine but moving it out of my way in my small 2 car shop. Note I did put better casters on it from Lowes.

I would doubt either of those CFM numbers as being what you could actually come close to in real life operation. Most manufacturers it seems inflate their ratings to include zero attached duct work and no filter on the exhaust. I have no idea why a conversion kit would be so expensive (or required). All quality single phase motors have only to be rewired in the junction box (five minute job if I’m a little off my game that day) and require no additional hardware beyond the appropriate plug to match the receptacle.

You have to replace this entire electronic remote start unit that’s why the conversion kit is costly.

I have a 2hp cyclone, and wish I had bought a 3hp. When you try to collect from sanders, the 2hp is just not going to do it. It works fine with my Grizzly 15” planer, just barely enough for my 12” jointer, and my unisaw plugs up at the 4” outlet on the cabinet, but am going to make a bigger outlet for the saw. Some equipment is designed better for dust collection than others. Sanding dust is the hardest to collect.

Please see the following links from the Grizzly site that show pricing for their 220v conversion kits: ($250 for G0703) ($91.95 for G0443)
When did you purchase your system? I wonder if Grizzly recently had a price spike on the G0703 220v conversion kit.

I’m glad to hear you are having good luck with your G0703. I have seen mostly positive reviews from other users as well. If the conversion kit is more reasonably priced I would consider it for my situation (very similar to yours).

Idaho that’s the entire unit, its also listed under 220/440 conversion kits, a call to Grizzly is probably in order.

Here’s what I purchased P0703088 CONVERSION KIT 220V, its listed as in stock $100. The kit is just a couple of circuit boards that you swap out internally you don’t get the whole box and front panel since you already have that. Hope this helps.

I purchased mine almost 1 year ago. Be advised they shipped me the wrong conversion kit twice. The incorrect kit was a big steel box and front panel, the whole thing like in your link only a different older design. I have a sneaky feeling this kit you linked to is possibly the newer version of that for the older machines. Again since the new machines already have those front panels and boxes, all you really need are the circuit boards and it looks like they are still available for $100.

Thanks for clarifying, that makes a lot more sense. $100 is definitely more reasonable. I had written off the G0703 due to that factor – now I’ll take a closer look at it. It will be a better fit in my small shop than a wall-mount cyclone.

I was standing in the Grizzly store in Springfield, MO, a few years ago. The store had a 2 hp and a 3 hp set up on stands on display. I was looking and comparing. a customer came walking through and said buy the biggest because you will end up with it later anyway. I did. HE went on. I later bought a Clearvue because if you buy any size at all you end up with a lot of money in it and I got a good deal (I felt) on the CV1800. I was poised for presidents day or some sale.

If I were buying a cyclone today it would be of the following. Note you get free shipping when purchasing directly from JDS and no sales tax. My local Woodcraft has the Laguna in stock no shipping and Oregon doesn’t have a sales tax. That’s the thing with my Grizzly purchases, since I’m in WA same as them I get hit with both shipping and sales tax which can add up to several hundred dollars to the price.

JDS 3HP $1,999

Laguna 3HP $1,695

JDS 2HP $1,499

I tried to buy this JDS 2HP before I purchased the Grizzly, they were always sold out and half the time their next order was presold it was pretty popular. I was going to wait the 6-8 weeks when Grizzly sent me a 10% off coupon and I pulled the trigger on the G0703. Don’t get me wrong I’m happy with the Grizzly but I owned JDS before they are good products. I saw the Laguna in person and it looks like a fine unit.

All three of the above have decibel ratings well below my G0703 which measures 94 decibels on my meter, its the loudest machine in my shop tied with my 5HP 12” beast Grizzly table saw.

I looked at some of the smaller grizzly DCs before buying a 5hp Clearvue. It fits inside a closet with a 28” by 45” outside dimension. This includes 4” thick walls for noise isolation and has room for a 55 gallon collection drum. I installed the DC, then built the closet around it. My shop is 13’ by 23’, it is about the same size as yours. The footprint of a large DC is not much different than a small one.

I just looked at the clearvue, the plastic construction turns me off honestly. Also they don’t list the height of the thing and it looks quite tall. Not saying its not a good unit its just not my cup of tea.
