Backpack blower vs gas

So I'm considering buying the backpack blower. Does anyone that has this that also had/still has a gas blower have any feedback?

Right now I have a Stihl that puts out AVG. AIR VELOCITY*
60 m/sec. (134 mph)
MAX. AIR VELOCITY*
71 m/sec. (159 mph)
Yes it's gas but it starts every time no problems. Its also a handled not backpack.

Eric,

Does the Stihl list the CFM?  There are two stats and for most the CFM means more for moving air. 

I found the high CFM of the ego performed as well if not better than the MPH of my Makita backpack gas blower. 

I wasn't sure about the backpack blower, because it didn't seem like much of a boost over the hand held, but it kind of takes it over the top enough to make it a proper gas replacement.

Stihls website doesnt list cfm's. I'll try to find out. The only thing i noticed is the controls seem a little clunky, a trigger/speed selector/and turbo. Wouldnt a variable speed trigger and trigger lock be less complicated?

Edit: heard back "The SH56C-E has 412 CFMS"

I bet the blower is rated in SCFM. But isn't displayed that way due to confusion. SCFM is based on "standard environmental conditions". CFM is Cubic Feet Per Minute. Which is subjective to your climate.

But talk about confusing people as all blowers are rated for CFM.

Good air compressors are rated for SCFM due to compression Ratio which takes into account atmospheric pressure, air density, humidity.

No, the worst thing going on right now is Electric blowers using the "Turbo" for their stated rating, which is a temporary setting as their CFM rating, when Gas you just use full throttle.  Nobody in their right mind would want to use the turbo setting for more than a few minutes at best. 

I really don't care for gov't regulations, but when it comes to marketing products, I'm glad they are trying to even the playing field.  I believe products should be rated with their standard highest setting.  No Turbo Boosts.

I'm not Knocking EGO here, they are just doing what everyone else does with Marketing.  It's the way of the world.  On regular high, the EGO blowers are awesome and move a ton of air.  So either way.

Hey Jacob,

I find this interesting because I'm into snow making.  Using compressed air at about 60psi mixed with water to freeze the water crystals and mix with bulk water nozzles to produce snow. 

On a positive not about older blowers, the compressed air is cooler coming out of the nozzles because as the air decompresses, it cools.  :).   Summer air conditioning.  It's just hotter by the operator  :)

So the motor bumps up the torque to maintain the same speed and in doing so needs to draw more current when the air density increases... If you want to confirm that, run the battery down inside the house once and then go outside and run it down again and compare and contrast the run times and also mind the pitch of the sound that the motor makes in order to check for RPM changes.

And I must say I don't really agree with what SCDC is saying about turbo boost, unless I'm out of my right mind for using turbo all the time on the 530CFM blower. I have two 2Ah batteries, two 2.5Ah batteries, and four 210W chargers. That is just short of what I need to run the blower indefinitely on turbo, so I have no reason to restrict myself to high. I use all my blowers on the highest power settings they have almost all the time because that gets jobs done quickly enough for me to compensate for short run times.

Hey Atom,

I don't remember where I read it, but EGO said it somewhere that they do not recommend using turbo but for short bursts.  I'll try to find it again.  Otherwise I agree with you.

I sold my Stihl this morning, hopefully I don't regret it haha. I think I'm going to get the backpack blower. Anyways one thing about the backpack blower that has me worried now is the lever for the speed control. I cut my thum bad as a kid, doctors didnt check it but I severed a tendon and my thumb doesnt bend at the middle joint. I might have to try to see if they have one in store so I can try out the feel of it.

Well, I hope it works out for you.
