I need some good advise please on a DC
#11
We need two tools very much
One is a dust collector and want to know if this one will work.  Both of them are less they $650

The above is 3hp with a 13.5" impeller in it, OR this one

https://www.amazon.com/Oasis-Machinery-D...+Collector

This one has a 5hp 12" smaller.

I am thinking it is not the HP but the size of the impeller which creates the best suction.

I am thinking for the price both would be a great machine's for us.

Any and all advice is most welcome on this.
As of this time I am not teaching vets to turn. Also please do not send any items to me without prior notification.  Thank You Everyone.

It is always the right time, to do the right thing.

Arlin what is your main source of chips 

Or what tools do you  need to hook up to a DC 

And how are you going to accomplish getting the chips to the collector?

Hi Arlin

I am backward on DC compared to many here. I would rather have 2 or even 3 DC's around the shop with only a 10' tubing between the machines, and the DC, and move them around as I need DC at any one machine. Cost is one reason, simplicity is the other. Tubing/ducting, whatever you use can be as expensive as the DC itself. Simple because all you need is a solid attachment at the tool, and use Male/Female connectors, or twist connectors to attach the two. For that reason I'd nominate something a lot simpler like this one from HF That model is in a lot of shops here, and does a pretty good job.

I like this connector, it threads into the tubing, and the smooth part fits most tools DC attachment. For some tools like a TS where the attachment is often only reached when you are crawling in to it, you can attach a small length of tubing to the machine, and using these be able to connect to you longer tubing on the DC machine.

HF has the DC units on sale often, and this is the time of year to catch sales on tubing, and attachments.

Arlin, they both have 30 micron bags, which makes them little more than dust pumps. To contain the finest particles you would have to have new bags and/or filters and that will really add to the cost.
I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.

You need a 1 micron pleated filter and a separator ahead of the impeller.
You will spend your life emptying bags with those units. Emptying bags requires a dust mask.
As above though, a lot depends on your shop and what you do

The '3 hp' figure looks a little iffy, but the impeller is consistent with a 3 hp unit.  It claims 12A at 240V, but without a run capacitor (only has one hump), it's not likely.  Static pressure (full stall, I presume) is typical, though you don't operate at or near zero air flow, so that figure is kind of useless.  What you really need is the flow vs SP curve, which most small DC manufacturers don't like to publish.

https://www.amazon.com/Oasis-Machinery-D...+Collector

This one has a 5hp 12" smaller.

This one looks like HF-style wishful thinking.  12A at 220V is 5.3 hp before taking into account efficiency (80% or less) and power factor (also 80% or less, unless it has a run capacitor, which it does not, at least in the picture), which would work out to 3.3 hp, or somewhere around there.  Probably a 3 hp motor.  And a small impeller, especially for '5 hp'.  

I am thinking it is not the HP but the size of the impeller which creates the best suction.

You're thinking is on the right track.  All other things being equal, increased diameter will increase the static pressure, and generally have a higher flow vs SP curve, and therefore move more air, and take more input power to do it.  Other things can influence it, strongly sometimes, like impeller vane shape (airfoil is much more efficient, for instance), but as a general rule, high hp units have larger diameter and deeper impellers with higher max SP.  High pressure blowers, for instance, can have thin impellers, but very large diameter.  Like a typical vacuum cleaner, or big industrial blowers designed for low flow at high SP. 

DC's are designed to move a lot of air at a medium SP, so they're narrower and larger dia. than a squirrel cage HVAC blower, but not as narrow and much deeper than a high suction 'vacuum', or high pressure blower.  With few vanes, so allow debris to pass without clogging.


I am thinking for the price both would be a great machine's for us.

I agree with the other posters about the 30 micron bags.  That's a non-starter for me.  There are other DC units with filters or 1 micron bags.  And do use a pre-seperator of some kind.  Emptying bags is a drag.

Any and all advice is most welcome on this.

This is what I have now is one from PSI that is 3/4hp and 500 cfm with the canister on top.
I do not know if you remember or not by the VA bought me these tools from Grizzly

and the DC that I have will only do the table saw and that is it.  I do not want any single dedicated lines just one line (Remember I only have a 14x16 garage) to go to any of them.

You also have to realize the price is very important to me. Sure I would love to get a top of the line Cyclone that I could use in my shop, but that is not reality for me and I can only afford so much and have been planning for almost a year for just the $500 I have now.

So if you have any ideas I would sure love them.

I'd consider the 3 hp Grizzly with 2.5 micron bags.

http://www.grizzly.com/products/3-HP-Dus...s/G1030Z2P

Or the 2 hp with 1 micron filter, but lower max SP (10 inches WG), so likely to pull less air through the same hose setup as the 3 hp at 16.7 inches WG.

http://www.grizzly.com/products/2HP-Cani...es/G0548ZP

But I'd lean toward the 3 hp, for the bigger blower, and upgrade the bags if necessary in the future. Remember that as they fill with fines, their filtration efficiency will go up, meaning they'll capture a higher percentage of each particle size range.

So the higher SP is better?  Also the 3hp grizzly is in our price range.

This one looks Really good to for a tad more.

What do you think?

Of the ones you've listed Arlin, the last one would be my choice. 1 micron filters, and plenty of air flow. Should serve you well.
