Tips: What is an air flow switch used for?
Air flow switches can be used in air filtration and supply systems, duct heating, exhaust ventilation, and more. Air flow switches are found in a wide variety of duct and HVAC systems, often using paddle operation to trigger a micro switch when the flow increases or decreases beyond a set rate or volume. In HVAC and ductwork, many air flow switches can also be used to perform operations such as air handling, fan monitoring, and filter monitoring.
