  • Suitable for installation in ceilings insulated up to R60
  • Dual access junction box simplifies wiring in tight spaces
  • UL listed for tub/shower enclosure when GFCI protected
  • UL listed for use with the Panasonic Ceiling Radiation Damper (model # PC-RD05C5 - sold separately)
  • 6 year warranty on ECM motor, 5 years on LED, 3 years on parts
  • Dual access junction box simplifies wiring in tight spaces

Installed Performance guarantees up to .375” w.g. static pressure and certified quiet operation at 0.25" w.g. static pressure
Although ASHRAE, ENERGY STAR®, LEED for Homes, and HVI have set the industry standard for performance measurement at 0.1” and 0.25" w.g., WhisperGreen® Select™ fans not only provide the powerful CFM output 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. So they are quiet under pressure and after installation.

Pick-A-Flow™ Airflow Technology – You Choose The CFM
Built-in Pick-A-Flow™ Airflow 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.

Plug 'N Play Modules To Build Your Perfect Vent Fan
WhisperGreen Select's customization features really kick in with a set of patented Plug 'N Play™ modules that give you the flexibility to design the perfect fan in advance, or on the fly, for a variety of ventilation applications. The first snap-in slot is dedicated to the pre-installed Multi-Speed (0, 30 to 110 CFM) module with high/low delay timer. The two remaining slots can accommodate the SmartAction® Motion Sensor and/or Condensation Sensor. Refer to the Accessories Tab for more information on our remarkable Plug ‘N Play modules.

ECM Motor- Best Performing, Most Energy Efficient Motor Available
WhisperGreen® Select™ features the same revolutionary ECM motor that comes with our WhisperGreen line of products. With built-in SmartFlow™ technology, WhisperGreen® Select™ is designed to perform as rated, providing precision ventilation. When the fan senses static pressure, its speed is automatically increased to ensure optimal CFM output. This feature provides peace of mind, as the installer doesn’t have to worry about compromising the fan’s performance.

New Elegant Grille with integrated LED Lighting
Our new redesign elegant grille has one integrated 10 Watt dimmable LED chip panel/3000 Kelvin Warm White/90CRI/700 lumens/70 LPW. The LED chip panel is ENERGY STAR 2.0 certified/JA-8 compliant for CA Title 24/50,000 hours rated average life/<1W LED night light.

Fast, Flexible and Easy Installation
The Flex-Z Fast™ Installation Bracket with single-hinge articulating joints to easily position bracket in between the joist and/or through ceiling hole installs the fan exactly where you want it, in old or new construction. WhisperGreen Select incorporates an integrated dual 4 in. or 6 in. 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 in. 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®- Certified for Energy Savings
