Key Features & Innovations

Panasonic-Airflow Technology

WhisperGreen Select is revolutionizing the ventilation fan industry with a new set of features that enable customization and easier installation. This all-purpose Indoor Air Quality (IAQ) solution gives you more than 250 possible configurations; through multiple flow rates, optional Plug 'N Play modules and installation flexibility. WhisperGreen Select is your total solution for indoor air quality, code compliance, green certification and healthy indoor environments.

Panasonic-Pick-A-Flow-Speed Technology

Built-in pick-A-flow speed selector provides the unique ability to select your required airflow (50-80-110 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.

Panasonic-Multi-Speed with Time Delay

The multi-speed module comes standard in models FV-05-11VKS1 and FV-05-11VKSL1. It can be added to the other models, leaving you with two remaining slots for the condensation sensor, motion sensor or night light.

The multi-speed with time delay module lets you select the proper CFM setting. The fan runs continuously at a pre-set lower level, then increases to a maximum level when the wall switch is turned on, or when the SmartAction motion sensor or condensation sensor module is activated. A high/low delay timer returns the fan to the pre-set CFM level after a pre-set period of time.

Panasonic-Condensation Sensor

The condensation sensor helps prevent mold and mildew in the bathroom. Advanced sensor technology detects relative humidity (RH) and temperature to anticipate the dew point, automatically turning the fan on as needed to control humidity. RH sensitivity adjustment enables fine-tuning for moist conditions and for CalGreen requirements. There’s also an automatic 20 minute delay off timer for the fan.

Panasonic-NiteGlow LED Night Light

The single-watt LED light turns on automatically in the dark. A Hi/Low brightness switch allows for fine-tuning the sensor to work with the darkness level of your bathroom. There’s also an automatic 20 minute delay off timer for the fan.

Panasonic-SmartAction Motion Sensor

The SmartAction motion sensor turns the fan on automatically when someone enters the room ideal for people with disabilities and assisted living environments such as nursing homes and retirement communities. There’s also an automatic 20 minute delay off timer for the fan.

Smart Flow Technology

The revolutionary DC motor with intelligent self-adjusting SmartFlow technology senses the amount of resistance in the duct run and automatically adjusts the fan speed to deliver the optimal CFM output, even in the case of a complicated duct run. The Panasonic DC motor with SmartFlow technology moves more air using less energy, so the fan is more energy efficient and lasts longer. Designed to run continuously, WhisperGreen Select can deliver whole-house continuous ventilation.


The Flex-Z Fast Installation Bracket with articulating joints is ideal for positioning the fan exactly where you want it, in old or new construction. WhisperGreen Select incorporates an integrated dual 4" or 6" duct adapter to give you flexibility in duct layout and design. For short runs, you can go with a smaller duct size, but long runs are ok too - just move up to the 6" duct. Also fits in 2 x 8 construction. Panasonic fans are UL listed for tub/shower enclosure (just install them on a GFCI-protected circuit). With these great features, your installation options open up.

Energy star

Panasonic ventilation fans are Energy star certified, where guidelines exist. They've been engineered to comply with the Energy star 4.0 requirement for increased efficiency (CFM/Watt), ensuring low cost, energy efficient operation. Energy star vent fans meet strict parameters set by the US Environmental Protection Agency (EPA). They provide better efficiency and comfort with less noise and feature high performance motors and improved blade design, providing better performance and longer life. WhisperGreen Select was awarded 2016 Most Efficient. This mark recognizes WhisperGreen Select as delivering cutting edge energy efficiency along with the latest in technological innovation. It is an award that represents the best of those products that qualify for Energy star
