you can try to convince yourself of that, Bob , but unless you consider a 45 a "BIG" blower , we'll have to disagree
To make lectromounts competitive in the market place there are some hurdles that must be overcome .
equal performance of a 45 blower @ 3000 rpm and 15HG
eliminate the need to get into Mrs Phiff's laundry rm to unplug her drier
Eliminate the need to find separate 20a circuits and then stretching a couple/three 100ft long 10ga cords
(while reminding Mrs Phiff not to use her blow drier, washing machine or blender while fridge compressor is running)
and you'll still blow breakers in many homes
Eliminate the PITA factor of all of the above WITHOUT using a generator the size of most 36 blower gas TMs (sans waste tank)
and they'll sell like hotcakes
the first lectromount maker to do all that while adding an "adequate" heat source that doesn't require secondary fuel like propane or kero, and they'll dominate the TM market in a few short years..
Make it affordable/competitively priced and the single wand gas TM will become obsolete
.L.T.A.
When I use my ETM, I use only 2 -15 amp circuits, no 20 amp, because 20 amp circuits are just too hard to find.
I use no generator - it defeats the purpose of an electric machine in the first place.
I never mess with the customer's dryer or washer, or stove, etc., to get power.
Now using electric for heat is just not practical. It would take at least 6000 watts of power for electric heat, and that still won't touch a good fuel fired burner. But using LP or Kero is a problem because most cleaners only want HX .
I use 12 AWG cords. 12 AWG will handle 20 amps up to 100'. You do not need 10 AWG cords, not to mention they would be a beast to handle. I usually run a 60' and a 50' cord, and still have a little left. They are on hand reels which makes them easy to handle. Rarely will I blow a breaker, but it does happen once in a great while.
With this setup I am getting 230 CFM (without the use of an inline vac booster) and 10 Hg. This is more than enough vacuum for any job up to 125'. 99% of my jobs are less than 90'. However, I do not have to slow my vacuum stroke, or do more dry passes with this setup when compared to my slide-in with a Roots #45 blower.
No, I do not consider a #45 as being a BIG blower. It is medium in size. A BIG blower would be a #59 or larger.
If you look at the poll at the beginning of this thread, you'll see most cleaners are NOT interested in an electric machine.
ZEE - Did a short vid today cleaning a Doc's office with dual wands. You can see the heat, and hear the vacuum - both of which are more than adequate to do a great job and have a satisfied customer. Used 1.5" wands each with #6 flow because of the close quarters cleaning. we usually run a 2" Titanium and 1.5" SS.
Later I will do one showing the inside of the van setup, the fact that the heater temp was set at 210º, and RPM's were at 3000, etc., but that will require a third person.
