WhisperSense FV-08VQC5 80 CFM, Ceiling Mount Fan

WhisperSense™ is a great choice for new and remodel residential applications. Time-tested and customer approved for quiet, yet powerful consistency. Rated for continuous use, WhisperSense vent fans are a simple way to execute an energy efficient ventilation strategy that helps prevent moisture buildup in your bathroom. This product protects your family from mold and mildew and helps maintain the structural integrity of your home.

Dual Sensor Technology (Motion and Humidity)

Panasonic's SmartAction® motion sensor automatically turns the fan on when you enter the room to automatically exhaust stale, moist air. A delay off timer can be set between 30 seconds and 60 minutes. A built-in humidity sensor can detect quick fluctuations in relative humidity and flip the fan on anywhere between 30% and 80% relative humidity - you pick. This eliminates moisture that can cause mold, mildew, decay, and rot. The auto shut-off switch saves energy and operating costs.

Long Life Means Reduced Costs

When you have a household or business to run, you don't want to have to replace little things like a vent fan. Panasonic fans use less energy to move larger volumes of air than other brands. Consequently, Panasonic fans run cooler so they last longer. They are also much less likely to overheat and result in motor failure. The motor is also equipped with a thermal-cutoff fuse.

Installation Flexibility

WhisperSense 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 6 in. duct. The double hanger-bar system (expandable up to 24 in.) is ideal for positioning the fan exactly where you want it. 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

Panasonic ventilation fans are ENERGY STAR® certified, where guidelines exist. 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.

Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Awesome Fan These things are great. Here in the pacific NW, mold growth is a serious issue at high relative humidity levels. Most folks don't leave their fans on long enough after showers etc. This fan takes all of the human error out of the equation, and runs the quiet fan until the relative humidity is at a safe level. One caveat: If you have high humidity levels due to bulk water intrusion, this fan might just keep running. It is an efficient motor, and will likely help the humidity in the room, but it's not going to fix the problem. That being said, this fan is great. October 26, 2012
