HVAC library for aecosim

Hello

We are starting using a mechanical part in our office and we have found a few problems with HVAC cells because some of them looks quite different than in a real life f.g. round dampers, some equipment etc. and it takes a lot of time to modify them. Does anybody know a hvac/plumbing manufacturer who have a library for aecosim? I haven't found any on internet.

I am using SS6
