Once you experience the superior level of comfort an American Standard TWE variable speed air handler gives you, you'll wonder how you lived without one for so long. And here's why. Inside a TWE is an electric motor that drives the indoor blower. In most standard systems this motor runs at only one speed, full capacity, and is either on or off.

American Standard's TWE variable speed motor is smarter than the average blower. It automatically varies its speed, based on heating and cooling demands.

And here's something else. Most conventional air handlers have only two or three fan speeds. But with the TWE there are 12 different CFM (cubic feet per minute) settings, meaning greater airflow flexibility and an enhanced level of comfort.

And since the TWE runs at a lower speed most of the time, there's less noise. It also ramps up slowly instead of coming on all at once, so there is no sudden blast of air.
