Venturi?, need a continuous airflow?, I suppose a NRV could help, but think I'll stick with the pump and a low-pressure switch. I've looked at the tables in the link - I think they'd work very well with sheet materials that would cover the vac table but I'm likely to want to play with fairly small boards (100x75) - think I need a table with smaller vacuum zones, so already looking at aquatic 4mm adjustable manifolds, miniature pipe benders and brazing kits. Well... it is the holiday season!
Have a look at the video on the table page - https://vacuumtables.co.uk/vacuum-ta...table-vt2012-r
They come with a length of black beading/gasket that you fit to the slots, so you can reduce the vacuum area to just the size you need.

Pierson Workholding have some good videos on how to use vacuum tables - https://www.youtube.com/playlist?lis...D1tNNi9COAyVlt

It's worth noting, you don't need to butt the gasket end to end. If you're not using the maximise size of the table, you can get away with running the two ends through the same corner from opposite directions.
