Product Description

Low-profile retrofit DC ventilation for fast fan replacement

The Panasonic FV-0511VF1 WhisperFit DC is built for remodels: its low-profile housing fits ceilings with just 5-5/8" of depth and 2 x 6 construction, so you can replace an existing fan from below without opening the ceiling. The DC/ECM motor with SmartFlow holds the rated airflow across 50-80-110 CFM via Pick-A-Flow, and the 4" adapter with backdraft damper (plus 3" reducer) lets you reuse existing duct. Quiet, ENERGY STAR-certified operation makes it a premium choice for bathroom renovations and hotel projects.

Top Features
