Thanks for the comments-
After writing AMMRL- which also gives fast and very useful responses, I
did think to contact TMC. It turns out we have 'precision' valves on our
anti-vibration legs, which constantly bleed air, and therefore require the
use of in-house compressed air or a compressor.
As our in-house compressed air will not be available during construction,
when our magnet will be de-energised and 'stored' we were looking for
other ways to keep the magnet floating while the building is demolished
and rebuilt around it. Compressed air cylinders are not the answer.
