Topic: HVAC Blocks

[TimSpangler]

Maybe someone here can help me>  I am looking for blocks or specs for hvac Round duct accesorries such as Elbows, t's Wyes. and takeoffs.  I am starting a new LISP project for mech and am triing to gather info.  I tried Gray metals (A large supplier of Ductwork) but all I get from them is an e-mail telling me to look in the catalog .  I lookied in the catalog and all it shows is the diameter (I believe a 6" duct would have a dia of,  6" )  I need to know lengths if possible or furmulas that are used to calculate the lengths

Any help would be appreciated.

They set the standards for HVAC duct.  Standards for dust collection systems is vastly different.

I don't quite understand you question about lengths.  Static pressure maybe?  -David
