|WhisperCeiling fans feature a totally enclosed condenser motor and a double-tapered, dolphin shaped bladed blower wheel to quietly move air. 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.
