GS electric motor specs

[Expo]

Anybody have a link or point me in the right direction to find specs on GS Electric vacuum motors?

Think I found it. Tyring to decipher what exact models the Surplus Center vacuum motors were, they finally responded.
16-1234 = G.S. Electric A213-3410-60 (series 013 thru flow)
16-1193-J = G.S. Electric A076-3450-25 (series 076 2 stage tangential bypass)
The specs they list at SC are not correct.

Specs for 16-1234


The 16-1193-J is the better one if you're trying for more depression than 28", and its cheaper. 10 friggin bucks.

is GS and Ametek the same company? I see surplus center lists the one motor as an Ametek. Is this one of the things that are incorrect?
Also,what is the difference between a "2-stage" motor and the other one?
thanks for the info.!

Apparently Ametek bought GS Electric a couple years ago.
2 and 3 stage motors are more efficient and can pull more CFM at higher vacuum than single stage units.

thanks for the great info.! I was ready to order the other ones for my bench, but it looks like that 2-stage motor is the one i really need, plus the extra savings on 12-16 of them isn't too bad either!
I'm doing a bench that will allow me to pull high depressions, so it looks like those are what I should have looked at to begin with.
thanks again

Using the spreadsheets provided by Terry T., here is what you get when you plug in single motor data into the spreadsheet, for the A076 motor. Ignore the 343 labelling. They are a little weaker than the 343 at low depression, and a little better at high depression.
