WhisperCeiling Ceiling Mount Fan

WhisperCeiling® large volume exhaust fans are ideal for light commercial applications. The workhorse of the Panasonic line, they are time-tested and customer-approved for their quiet yet powerful consistency. Rated for continuous use, WhisperCeiling vent fans are a simple way to incorporate an energy-efficient ventilation strategy.

We Set the Standard for Quiet Operation

WhisperCeiling fans feature a totally enclosed condenser AC motor and a double-tapered blower wheel to quietly move air-even at twice the static pressure as the industry standard. The fans exceed the performance measurement for ASHRAE 62.2 and LEED for Homes.

Long Life Means Reduced Costs

When you have a household or business to run, you do not 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

WhisperCeiling large volume fans feature a 6 in. duct adapter and fit in 2" x 8'' construction. The double hanger-bar system (which is 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.
