Above is the double sided concept.

I would like to use gaskets like these:
All Star Adhesives - gasketing products for CNC routers and v-groove tape for v-grooving and coving applications

My table size:
The tables overall length is 178" (y axis).

The width of the table is 82.5" (x axis).

The table is made out of flat aluminum that the gasket should suck down to nicely.

I would like to do small production runs.

I plan on cutting .063" aluminum sheet. I will nest many pieces onto a 48"x144" sheet. Each "piece" will have a small gasket that holds the item in place. this fixture will also double as my spoil board, since i will be making the same exact parts, it wont destroy anything. I was told a much smaller vacuum pump/s can be used with this gasketed fixture method, and also allow me to swap out different fixture for different runs. If you look at the second picture i attached i would gasket each part like that, but the rear of the fixture would have a overall gasket to suck it to the table.

I currently do not have a pump at all. I have $1100 dollars to put towards a pump.

I need help selecting the best pump for the $$.

Just a few options i have found for pumps.

Grainger

Regenerative Blower: $986.00
Blower, Regenerative - Regenerative Blowers - Air Compressors and Vacuum Pumps - Pneumatics : Grainger Industrial Supply

Vacuum Pump: $738
Evacuation Pump, 1/2 HP, 9.53 CFM, 3440 RPM - Vacuum Pumps - Air Compressors and Vacuum Pumps - Pneumatics : Grainger Industrial Supply

MotionTek
Regenerative Blower: $381-$584 (USD converted from Canadian)

Harbor Freight
Vacuum Pump: $99
Electric Vacuum Pump - 2.5 CFM

Vacuum Pump: $149
Air Conditioning Vacuum Pump - Two Stage, 3 CFM

Air tanks: 11 gallon $34.
11 Gallon Portable Air Tank

I'm limited to single phase 240VAC (amperage doesn't matter), and $1100 dollars. I also can acquire 100 gallons (or as much as needed) of air tank storage for holding surplus vacuum for faster fixture "snap down".

Thanks for all the help!! Shoot me any pump/info that you feel is necessary!
I don't know much about those pumps or how to compare them for what i will need.
