Delta Breez VFRU-25-32DA – Frequently Asked Questions
1) Will the Delta Breez Signature G3 duct adapter connect a 6 inch fan outlet to 4 inch duct?
That is exactly what the Delta Breez SIG G3 plastic duct piece does: it takes the 6 inch outlet down to 4 inch duct. The outlet side of the part is 4 inches, so it mates to standard 4 inch flex or rigid duct downstream. If your run is already 6 inch all the way to the cap, you do not need this piece at all.
2) What do I order for a Delta Breez SMT fan going into existing 4 inch bath duct?
The part to add is the Signature G3 plastic duct reducer, model VFRU-25-32DA, which brings the 6 inch fan connection to a 4 inch outlet. It comes as a single model with no size or finish options to pick, so there is one part number to specify. You still supply the duct itself, the clamps or tape, and the exterior cap.
3) Does using a 6 to 4 inch reducer on a bath fan hurt airflow?
Any step down from 6 inch to 4 inch raises static pressure on the run, so keep the 4 inch duct short, straight, and rigid where you can, and hold elbows to a minimum. Where the ceiling cavity and the cap will take 6 inch duct, running full 6 inch is the better install. Use the reducer when the existing 4 inch duct in the building is what you have to tie into, which is the usual case in a retrofit.
4) Is the Delta Breez SIG G3 duct adapter plastic or metal?
Plastic. That keeps it light for an overhead attic connection and it will not corrode from the moist air coming off a bath fan, but it is not a fire-rated or grease-duct component and should not be used outside bath and utility exhaust.
