Are there any such AHUs avialable which have built in sound attenuators. Meaning inside the AHU body, immediately after the blower fan...there is sound attenuators. Thanksj

Fanwall AHU systems do this. The sound attenuation is inside each fan cube. We are about to install this where I work, meaning we can remove the attenuators in the supply plenum.
Yes, but most all would be custom manufactured units. What CFM range are you looking for?

I have looked few catalogs, Carrier, Trane for instance but don't find any attenuators inside the AHU.

It is 18000cfm AHU and I have been installing attenuators in my previous designs in the supply air ducts. Looks like you are right, these are mostly customized built AHUs which have attenuators inside. Just curious how and where ther are located, must be i impacting the Overall static as well. Would be great if someone could share a sketch or pic of the same.
Look at Temtrol line. And consider again the Fanwall technology...attenuators are right at each blower, not in the duct.Quote:
