There was a time when I was gainfully employed as a design engineer and this type of discussion would surface periodically in design reviews because it was always pertinent to everything that was currently under a new design/discussion. It usually devolved into a discussion of what's theoretical vs what's reality.

These long-winded discussions were usually boring as hell because it was easier to just go into the lab and prove that the theoretical aspect was a bit off.
So let's start with reality:
From the owners manual of the CT 15 E & CT 25 E...the max is 240watts.
From the owners manual of the CT 26 E & CT 36 E...the max is 1440 watts.
From the owners manual of the CT 36 E AC...the max is 1440 watts.
From the owners manual of the CT MINI & CT MIDI...,the max is 1200 watts.
From the owners manual of the CT 22 & CT 33...the max is 1200 watts.
From the supplemental issue of the owners manual for the current CT dust collectors...the max is 1200 watts.
From the owners manual of the CT 36 E AC HEPA...the max is 444 wats.
From this...folks are free to come to their own conclusions and after running a Kapex plugged into MIDI for the last 5 years, I have no issues with the Festool vac and consider the low amperage ratings as BS.
From a common sense standpoint does it make sense that the most inexpensive vacuums and also the most expensive vacuums would have the lowest amperage ratings while the bunch in the middle would be perfect for the job?
