To help you meet stricter ventilation codes and indoor air quality standards, our optional model (FV-0511VFC1 (Fan/Condensation Sensor) includes onboard humidity sensing that delivers effective moisture control and healthy indoor air. Advanced sensor technology detects relative humidity and temperature to anticipate dew point, automatically turning the fan on to control moisture.

The onboard delay timer runs the fan for 20 minutes when power is first turned on. After 20 minutes the fan turns off automatically unless moisture level is above the trigger point or the red wire circuit is closed. When the fan senses moisture levels above the trigger point or if the moisture level rises suddenly (from a hot shower for example), the fan automatically turns on. When the moisture level is 5% below the trigger setting, the 20-minute timer starts again.

Built-in Pick-A-Flow® airflow selector provides the unique ability to select your required airflow (50, 80 or 110 CFM) with the simple flip of a switch. Being able to choose the proper CFM level gives you the flexibility and assurance that one fan will satisfy a range of ventilation design requirements and perform as promised, even with a complicated duct run.

ASHRAE, ENERGY STAR®, LEED for Homes, and HVI have set the industry standard for performance measurement at 0.1" and 0.25" w.g. WhisperFit DC fans provide powerful CFM airflow at 0.375" w.g. that is more representative of most installations. Sones have also been certified at 0.25 w.g. to provide a more realistic, installed value.

WhisperFit® DC is the perfect solution for any remodeler looking to quickly and easily replace an existing fan from below the ceiling. This fan enables you to utilize existing duct, while its low profile housing design ensures a proper fit in any ceiling with at least 5 5/8” depth. The single-hinged Flex-Z Fast® bracket provides flexible, fast and easy installation for easy positioning through a ceiling cavity. The slide and snap-in junction box and duct collar provide greater flexibility when wiring and attaching the duct and this premium fan now includes preinstalled plastic alignment guides and temporary retaining clip. These clips molded into the casting will allow the fan to stay in place while the installer fastens the fan into can. Once installed, use the Pick-A-Flow® airflow selector to customize the airflow to meet your customers’ needs. All of these great features combined make WhisperFit® DC a fast and easy to install ENERGY STAR® retrofit fan.

ENERGY STAR® certified vent fans meet strict parameters set by the US Environmental Protection Agency. Panasonic ventilation fans are ENERGY STAR® certified where guidelines exist, and provide greater efficiency and comfort with less noise. High performing motors and improved blade design deliver superior performance and long life you expect from a premium Panasonic ventilation fan.
