Using the ES line of motors, the additional STL models provide maximum air flow coverage for all room and area configurations.

Using the ES line of motors, the additional STL models provide maximum air flow coverage for all room and area configurations.

The STL 2.5 bridges the gap between the ES 2000 and 2850.

In every configuration, dealers can mix and match our ES and STL motors for perfectly zoned coverage with the industry's most energy efficient fans, all of which sit atop the California Energy Commission "Appliance Efficiency Database" as the most energy efficient fans on the market.

As we like to say, if it doesn't say "QuietCool" on the motor, it's just another fan! But more ---- these say "Stealth," the best of the best offered by QuietCool.
