I have just received an update from Maintenance on the fume hood repair, but unfortunately it isn't great news:

Theres is currently an issue with the frequency drive for the manifold. It is currently running but not a full setpoint. This could cause some fume hoods not reach recertification level. The electric shop has spoken to the vendor about getting the replacement part and am waiting on an ETA of when that will be.

I will update again as soon as I know something new.

Thank you.
