High powered vacuum tube
WebHigh-Efficiency Fixed-Flow Air-Powered Vacuum Pumps. A multistage design generates a high vacuum flow with less air consumption than other air-powered vacuum pumps. Also known as venturi pumps, these pumps are commonly used in vacuum packaging, pick-and-place operations, and end-of-arm robotic tooling.

You can use 2 parallel 2u2 630V film capacitor to replace them, they are $4 each. The electrolytics are a lot cheaper, you can use 33uf 450V Nichicons as replacements for the 47uF ones, they are under $2 each.
