Belimo LMB24 Motorized Damper For HVAC Systems – 20 Sizes, 24V, Commercial Grade, Made In USA

Upgrade your HVAC zoning with this top-of-the-line Belimo LMB24 motorized damper, built right here in the USA.

Whether you're working on a commercial project or a residential retrofit, this bad boy’s got you covered.

It comes in 20 different rectangular sizes, so you can mix and match to fit your ductwork perfectly.

The actuator runs on 24 VAC and sips power—only 2.2 watts—while giving you a smooth 95-second operation.

That means no sudden pressure changes or banging noises, just quiet, consistent airflow control.

Plus, the actuator stops in any position when the power’s cut, making it super flexible for all kinds of setups.

The housing is all aluminum and stainless steel, so rust and wear aren’t an issue.

And with a 20-year proven track record and a 5-year warranty on the motor, you can install it and forget it.

Also includes rattle-free nylon bushings and a commercial-grade 1/2-inch drive shaft.

Works with standard thermostats—no extra relay needed.
