Cleveland Controls ANA-126-310 Air Pressure Sensing Switch Fixed Set Point

The Cleveland Controls ANA-126-310 is a factory-calibrated, fixed set point air pressure sensing switch engineered for OEM HVAC and air-handling equipment applications. Part of the proven Series ANA switch family, this unit provides reliable electrical switching action in response to low positive, negative, or differential air pressures — making it ideal for proving airflow in furnaces, duct heaters, air handling units, and commercial HVAC systems.

Series ANA switches are designed around a sensitive diaphragm mechanism housed in a durable plated steel enclosure. A snap-acting SPDT (Single Pole Double Throw) switch delivers crisp, dependable circuit control on pressure rise or fall, suitable for both control and alarm circuit integration. The fixed set point design eliminates field adjustment variability, ensuring consistent, repeatable air pressure proving performance right out of the box.
