Also known as barometric dampers, these dampers improve furnace performance by automatically opening and closing to maintain consistent airflow despite changing environmental conditions.

More convenient than other blast gates, these automatic gates open and close in sync with dust collectors, fume exhausters, and other machines.

Made of PVC, these louvers stand up to acids, alkalies, salts, and corrosive vapors in harsh environments and won’t rust.

These louvers are gravity operated. The blades open when your roof-mounted exhaust fan goes on and close when it's off, preventing backdrafts.

Actuators automatically switch between incremental and proportional control to adjust dampers to regulate airflow.

Made from stainless steel for excellent corrosion resistance in damp environments.
