CBX32MV Variable Speed Air Handlers
Home Comfort Systems
CBX32MV
Quiet, environmentally responsible air
handler for virtually any application

Comfortable
Increases comfort and efficiency,
while minimizing sound
The variable speed motor ramps up
to speed slowly, instead of reaching
full capacity all at once. By gradually
varying its speed, this motor runs
more quietly and efficiently, and it
delivers more even temperatures than
conventional single-speed motors.
Designed to deliver on every comfort count, Dave Lennox Signature®Collection
air handlers use innovative variable speed technology to maintain even
temperatures, while slowly circulating air throughout your home. Slow, steady
circulation of air results in lower humidity levels and better air quality.
Lennox’ variable speed air handlers deliver exceptional comfort, quietly
and efficiently. The variable speed motor gradually increases speed, so there’s
no sudden blast of air at startup. And compared to a standard motor, they use
two-thirds less energy. They take technology to new heights, so your utility
bills reach new lows. You gain comfort and save money.
