I have heard about the problems with the S**tplex (Simplex)
platters, I was once visiting a theatre booth that had the
platters equipped with blowers. I can't remember if they
were Potts or CFS,but which model(s) or brand? Were the blowers for
the bearings?

the only platters I know of that had blowers were air platters. I can't remember the model or brand of them. I do know thay were loud. Basicaly air was used to turn the platter decks. These things were very notorious for having film problems. If you looked at them wrong it would effect the speed of them. I hope I never see one again.

Potts made the simplex platter and it was the only air driven platter-thankfully

Why would anyone engineer an air-driven platter? Was there thought to be some advantage to air, over regular electric motors?

No it was just the first north american built platter and I assume they were trying to work around the norelco/kinoton patents

I believe they were Super Platters so I assume they were CFS.
I assume most were converted to non-blower use.
I assume the blowers were for payout only.

>>I believe they were Super Platters so I assume they were CFS<<CFS nor ORC *EVER* made the Super with 'air blowers', they are all friction roller driven from electric motors, and always have been. Are you possibly confusing the drive motors with some kind of blower device? (granted the drive motors are a variation of a vacuum cleaner motor, but with a differing use).
You must be confusing with the Simplex platter, which is the only one i have ever heard of that used the air-blower drive.

It was called 'The Aerowind', it was blue, sold by NSS and carried the
Simplex name. underneath the bottom disc was a blower much like a vacuum cleaner. I was 'lucky' enough to get two in these in a small booth. When you turned them off at night they sounded a little like
jet engines whinning down and would take a while,much like having
generators in the booth.

Actually NSS marketed them as the Simplex 'Aeromatic' or 'SAM' Platter. They were very noisy, and after a couple of people got scalped by the braces under the discs, Simplex discontinued them. Bob Potts went on to build an electric platter. The braces under the discs were a Z extrusion (with SHARP edges)and had the leading edge of the Z facing the direction of rotation! Thus, if the operator placed his head under a rotating disc, (to pre thread the disc, etc) and raised up, the Z metal would remove a piece of his scalp!! I know of two operators that this happened to!------------------
