Delta Breez VFRU-37-06DA – Frequently Asked Questions

1) Will the Delta Breez duct adapter let me connect a RAD bath fan to 4 inch duct?
That's exactly what it does. The Delta Breez RAD duct adapter steps the fan's 6 inch outlet down to 4 inch, so you can run the existing or planned 4 inch flex or rigid duct straight off the housing. If the run is already 6 inch, you don't need the adapter at all.
2) Does the Delta Breez plastic duct adapter fit every RAD Radiance model, or only the RAD80?
It fits all RAD models. The adapter is part of the Breez Radiance line and is sold as the common 6 to 4 inch reducer for that family, so you can stock one part across a building where some units are RAD and some are a different RAD size.
3) I'm reducing a Delta Breez RAD fan from 6 inch to 4 inch duct. Does that hurt airflow?
Reducing narrows the outlet, so the shorter and straighter the 4 inch run, the better. The RAD unit the adapter serves is an 80 CFM single speed fan sized for spaces up to 80 square feet, and it's rated at 1.5 sones. If you have a long run or several elbows, keeping 6 inch duct and skipping the adapter is the better call.
4) Do I need anything else electrically when I install a Delta Breez RAD fan with heater?
The duct adapter itself is a plastic fitting with no electrical connection, but the RAD heater fan it mates to needs a separate 15 amp circuit. The heater module runs a 1300W element with a thermal cutoff fuse and thermostat, so plan the branch circuit before you set the housing, not after the ceiling is closed.
5) Where do I find the duct connection details for the Delta Breez RAD fan before I rough in?
Delta Breez publishes both an installation manual and a submittal sheet for the RAD unit, and ZenSupply hosts them with the 6 to 4 inch adapter so you can size the rough opening and the duct run off the same documents the inspector will want.
