I guess going back to the wall supply would be a stupid step backwards. We need to fix this leak, its either in the tubing or the air springs themselves.
Can you check out what the connection to the air springs is and whether this can be connected to the standard clear tubing airlines? We are using the standard 1/4" tubing (see Newport Pneumatic Isolator Accessories). I'm not even sure if they are supposed to be permanently hooked up to air, the Newport air springs seem to have a Schrader valve (cars/bike valve) on the side and the description suggest that they only need to be pumped up and leveled once. They do degrade. If that is the case then we need to assess if these older rubber diaphragms need replacing.
This is moderate priority. Scattering is top of the list.

We need to return this cylinder when getting a new one. It will need to reach the low 100s, then we hit reorder on N2.

Ever since I attached the vaccan air springs to the cylinder, it has been rapidly losing air pressure. It is now down to ~1100 psi, where on Thursday it was ~1800 psi. At this rate we will have to order a new cylinder, and figure out how to make the air springs less leaky, as this is affecting our alignment over time.
For now, I'll relock the cavities, replace the shims, and turn off the air springs as they are causing more harm than good. We will rely on the floating table until then.
