hey guys, jumping in late here, I had a question in regards to McRabbets post about the small piece of wood in the blower outlet, I dont see that anywhere in my unit, i have the straight transition that will be going into filters via 8" insulated pvc. I am currently in works and planning stages of building a closet and any and all advice is welcome (types of insulation, quietrock vs sheetrock, anything to get the noise of this thing down. I have a cv1800 with a 16" impeller in a 30x30' detached shop with 10' ceilings and this thing is loud, so loud that I cant carry on a conversation at all. I expected it to be loud but it sounds like a jet engine. Just wondering if this piece of wood may have something to do with it. Thanks guys.
