Exclusive Dual Sensor Technology

This WhisperSense™ model features Exclusive Dual Sensor Technology that reacts to both motion and humidity, automatically turning the fan on when needed. No effort is required.... the fan does all the work for you.

Built-in SmartAction® motion sensor automatically turns on when you enter the room.

No more forgetting to turn the fan on with Panasonic's decision free technology.

A built-in humidity sensor detects rapid rise in relative humidity (RH), automatically turning on the fan to remove moisture and helping to prevent mold and mildew.

Built-in adjustable delay timer can be set from 30 seconds to 60 minutes and activates when motion is no longer detected or when humidity levels are below preset levels.

Already remarkably energy efficient, our auto shut off feature can help eliminate unnecessary energy use and further reduce operating costs.

Quiet Operation at .25" Water Gauge

Since .1" w.g. is an unrealistic amount of static pressure when installed, our fans have been rated at .25" w.g., the industry standard for performance measurement for ASHRAE, ENERGY STAR®, LEED for Homes, and HVI. Panasonic leads the way with incomparable sone levels at both .1" and .25" w.g.

ASHRAE, ENERGY STAR®, LEED for Homes, and HVI have set the industry standard for performance measurement at .25" w.g. The new WhisperWelcome fans not only provide powerful CFM output at .25" w.g., but our sones have also been certified at .25" w.g. So they are quiet under pressure and after installation.

ENERGY STAR®-Qualified for Energy Savings

ENERGY STAR®-qualified products feature super-quiet operation and high CFM-to-Watt efficiency. The ENERGY STAR program was created to help consumers identify products that can save them money and protect the environment by saving energy. As an ENERGY STAR partner, all of our fans are ENERGY STAR-qualified and labeled accordingly.

User-Friendly Installation

Detachable 4 or 6 inch adaptors, firmly secured duct ends, adjustable mounting brackets (up to 26"), fan/motor units that detach easily from the housing and uncomplicated wiring all lend themselves to user-friendly installation. This model also features a double-hanger bar system for ideal positioning.

Tired of Cold Air Coming Through Your Ventilation Fan?

This Panasonic fan has a built-in damper to prevent backdraft, which helps to prevent outside air from coming through the fan. Also, thanks to our efficient, cool running motors, it does not create excessive heat. Loose fill or battery insulation can be placed directly over the fan housing to prevent heat from escaping.
