Humidity Sensor

The Humidity Sensor helps control bathroom condensation to prevent mold and mildew. Sensor technology detects relative humidity and temperature to anticipate dew point, and using an adjustable delay timer, air pollutants are eliminated from the room - ultimately increasing your air quality.

Pick-A-Flow® Airflow selector - one fan, you choose the CFM

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

Easy roomside installation for contractors and DIYers

Flex-Z Fast® installation bracket with articulating joints provides fast and trouble-free roomside installation from below the ceiling. The detachable installation adapter makes it easy to work with as it simply slides off the fan housing for effortless wiring and duct attachment, all from beneath the ceiling.

No rewiring or new wall switches needed. UL Listed® for tub and shower enclosures when GFCI protected. 

Long life, lower cost of ownership

Panasonic fans use less energy to move larger volumes of air than other fans, and they run cooler so they last longer, providing efficient ventilation and healthy indoor air for many years. The built-in thermal-cutoff fuse practically eliminates chances of overheating which can result in motor failure, which means this may be the last vent fan you ever buy.

ENERGY STAR® certified for energy efficiency & savings

ENERGY STAR®-certified vent fans meet strict parameters set by the US Environmental Protection Agency. Panasonic ventilation fans are ENERGY STAR certified and provide greater efficiency and healthier indoor air quality with less noise. High performance motors and improved blade design deliver the superior performance and long-life operation you expect from a Panasonic ventilation fan.
