Delta Breez Pro300 – Frequently Asked Questions
1) How much ceiling space do I need to frame for a Delta Breez Pro300?
The housing measures 15 x 15 x 7-3/4 inches, so it is a deep box, not a slim retrofit fan. That 7-3/4 inch height rules out a 2x6 joist bay and most shallow plenums. Confirm you have the depth above the ceiling before you cut, and plan the opening around the 15 inch footprint.
2) What size bathroom or room will a 300 CFM Delta Breez Pro300 cover?
Rated for spaces up to 300 square feet. That puts it in master baths, large multi-fixture washrooms, and light commercial rooms rather than a standard 5x8 bath, where 300 CFM is far more air than the room needs.
3) Can I mount the Pro300 exhaust fan on a wall instead of the ceiling?
The Pro300 is UL and cUL listed for ceiling mount installation. Plan it as a ceiling fan.
4) How loud is the Delta Breez Pro300 at 300 CFM?
2.0 to 2.5 sones depending on static pressure. That is quiet for a fan moving this much air, but it is not silent the way a 50 to 80 CFM bath fan is. In a bedroom-adjacent bath, expect to hear it running.
5) Is the Delta Breez Pro300 Energy Star qualified for a rebate or green build spec?
Yes, the Pro300 is Energy Star qualified, which is what utility rebate programs and green building specs usually ask for on exhaust ventilation.
6) Is the Pro300 a single speed fan or can I set the CFM?
Single speed, fixed at 300 CFM. There is no speed selector or CFM dial, so if the design calls for a lower balanced rate or a multi-speed unit, this is not the fan for that opening.
7) Will the Delta Breez Pro300 hold up in rental or multifamily units?
It uses a brushless DC motor, which Delta rates as outlasting a typical AC motor by 2-1/2 times. For a property manager standardizing across units, that is the practical argument: fewer motor callbacks, and one part number across the building.
