Steve, the nozzle is an add-on component that flattens the airstream. It also fits the 530 cfm model:

Next, we need to make a backpack blower just like the other one except with cruise control and bump up the power enough to bring the volume up past the 700 CFM mark. I and the pros would like to see 750. That would make the speed 181.25mph, enough to compete with gas powered professional models. That would be about a 35 newton force, enough to match the Stihl BR700.
A quick way to make the volume adjustable without making the power adjustable would be to add a ducted fan front attachment that is larger in diameter than the tube, and allows for air to come in the back side of the ducted fan and go out the front. This attachment can convert 750CFM at 181mph to 900CFM at 145mph, the bigger the diameter ducted fan, the slower the air speed and the higher the air volume, have one with double the cross-sectional area to convert 750CFM at 181mph to 1500CFM at 90mph. Thus would be a quick and easy attachment.
There is your ducted fan. Let the air's force spin the fan.
I need a way to upload videos. I can further explain what I'm aiming at with a video that I just created.

I think we'll see an adoption of multi-stage axial fans in cordless blowers at some point in the not too distant future. Much more practical to operate at the higher pressure ratios these high performing tools will demand.

https://youtu.be/_qBfRSUplk0 Here are further details on the backpack blower concept.
Blue, I suppose that's a possibility. Ryobi's 520CFM gas axial blower uses a 3 stage fan system.. Do note though that you can get 750CFM at 181mph in the 600CFM backpack blower just by making the fan spin faster, make it spin about 1.3 times its speed that delivers 600CFM at 145mph.
As far as jet engines go, I prefer ramjet over turbo jet, but you aren't going to be moving the leaf blower at mach 3 to make it operate. I want to make an RC plane that uses ramjet.

TAT, there's a limit to how fast you can spin a fan before you get into supersonic speeds, shockwaves and stuff. I'm no expert on that stuff, but maybe you could see how close we are by calculating fan tip velocity from RPM and diameter?
Oh, and if you go too far you'll tear the fan apart and end up with bits of shrapnel to pull out of your various fleshy bits. :-)

Blue, yeah. Everything has a point to where it just breaks apart, either from vibrations or force. I'm sure the EGO Blower could be pushed quite a bit beyond what it is set at. For safety and durability, it's probably dialed down 10 to 20% of what it is capable.
Nobody wants a product that breaks after a few uses, or is walking hazard. I think EGO takes safety just a tad over the top on some things with too many activation checks/switches, but I guess with the average joe IQ dropping to prehistoric levels, it might be warranted.

I believe centripetal force increases as a square of the velocity, so even if Ego has a 100% safety factor built into the fan's structural design, it wouldn't take much of a speed increase to fail it. But for all I know the factor could be 1000%, all speculation. :-)

The 530 gives roughly 1.5 to 1.6 kilograms of thrust.
Also, The tip speed of the fan is spinning at about 113 m/s at 24000RPM Even if you double that, you're still subsonic. Also, if you're worried about max fan rpm, you can always make the fan out of aluminum. The JP fan can pass 80000RPM safely, but in order for that to work, the fan must be balanced very well. Many 90mm ducted fans for RC planes can pass 40,000 RPM, and the 530CFM EGO fan is a 90mm, so is the 480CFM's. I should note, and not to bash EGO, that their fans are not all that well balanced compared to the higher-end fans sold for RC planes.

https://www.youtube.com/watch?v=QahiKk0vlVE Here is a video of a 90mm JP fan in action. If you mind the frequency of the fan whistle, divide that by 12, and you have the number or revolutions per second. Mind the Doppler effect.

Dude, you can't compare the manufacturing of an injection molded plastic fan from a mass-produced leaf blower to a cnc machined billet aluminum fan from a bleeding edge high performance rc jet edf! Kinda apples and oranges, don't you think? ;-)
Some small turbochargers spin in excess of 200,000 rpm... probably beyond what ball bearings can handle.
That 90mm JP at 88,000 rpm has got a tip velocity of about 415 m/s, well into supersonic territory even before you consider the pressure/temperature drop at the fan inlet. Maybe it's not that big a deal, or they're just designing for it?
Pretty awesome looking plane! Incredible what electric RC has grown into since my days of wishing I could afford the "high" capacity yellow 1500 mAh Sanyo 7-cell packs instead of the plebeian red 1200 mAh Sanyos the poor kids ran! :-D

no, not really not when you've taken these apart before, but I do see where you're coming from. The fans weren't designed with such high tolerances in mind because they would drive the price up and they weren't really needed, so in a way, if I were "bashing EGO", it would be for an unjust reason. Additionally, JP fans are some of the finest on the market. The only reason I brought it up is because I wouldn't recommend bringing the rotational velocity of the fans up beyond 30,000 or 40,000 RPM because the balance isn't really enough for the motor to handle it, assuming of course that the motor wouldn't fail as a result of too much current going through it, and that the motor might fail before the fan did.
Finer tolerances will be needed for faster spinning fans, and I don't know how fine the tolerances are for the backpack blower, but bringing the fan's rotational velocity from 27,000 RPM to 35,000 RPM might require an increase in the tightness of manufacturing tolerances. 35000 RPM would be around what would be needed to push 750CFM at 181mph out of the LB6000 unit. It's really only a few small manufacturing tweaks that would be required to accommodate this. The big question in my mind is how many watts will that require? note that the LB6000 is a 1000 watt unit.
SCDC, as far as engineering OCD goes, I'd hardly consider doing all the time what I love to do OCD, I call it following my heart, just like I love using the blower to blow stuff around as I observe the behavior of the air. Anyone might think I have OCD because of how clean my yard ends up, but if I didn't enjoy it so much, I wouldn't be doing it. Also, if you were just joking, sorry for ruining it.

Aah.. jet engines. I miss the days on the flight line. If I got a leaf blower that had all those stages of compression, I would have to feed gasoline into the tip and light it, because with all that power, it would need afterburner. Where did all the leaves go you ask?

Ok, you guys like math. How many 575 CFM blowers would it take to move a 1.1 ton car on a level surface? I've always been curious about this. I know that there isn't much thrust with these things, but it still fascinates me.
-
13,128 Points
It depends on the friction involved. If the surface was completely frictionless, then you would need just one, but the car would accelerate extremely slowly. Each 575 unit puts out about 17.5 Newtons or about 1.78 kilograms (about 3.9 pounds) of thrust. 550 of these blowers would put out enough force to make the car hover in the air. In order to know how many it would take to make the car move, you'd need to how many pounds of force it would take to make the car move, assuming that the parking brake is off of course.
(Edited)
-
13,128 Points
Actually, if you made the car battery powered, EDFs at the back and sides would give you an excellent advantage in drag races if you can get the fans spinning fast enough. An extra 10000 Newtons (enough to get one ton from 0 to 60 in 2.7 seconds if there is no friction and no air drag) of force from air would give you a tremendous start. You could get that from 200 high-thrust EDFs and a giant battery in place of the engine.

In Canada NO ONE KNOWS WHAT EGO IS. When I tell them about EGO they reply ``ECHO??``

A buddy of mine and I got ours from the US. We're not far from the border here in Ottawa.
If it was made available as a bare tool it would be great, but the kit version with 5Ah battery would be prohibitively expensive if HD followed their usually ridiculous Canadian pricing strategy:
In the US the 5Ah backpack blower kit sells for $300 and the 5Ah 575 blower kit sells for $350 ($50 too much in my opinion).
In Canada the 5Ah backpack blower kit sells for $500! So the 5Ah 575 blower would sell for $550? $580? $600? Who knows...

I'm going to say it's pretty much a Home Depot/Ego thing. When you consider the exchange rate, there are certain things that are actually cheaper at Home Depot Canada then in the US.
Unfortunately, Ego's products are not included in that group and are decisively the other way.
It really makes me wonder how motivated Home Depot Canada is to sell Ego, especially when you consider how little stock they have of the higher end stuff and how they consistently run out of things halfway through the season.

As far as "too many blowers" goes, take comfort in the fact that this 575 model appears to be mostly an upgrade to the existing 530 model, which undoubtedly is a much more efficient process from a product development point of view. This means less Engineering hours invested so more can go into cool new things like the soon-to-arrive multi-tool. :-)
