Compressed air is carried via copper and plastic tubes from a controller to a control device, usually a damper or valve actuator. This control method relies on sensors and thermostats that bleed or retain the line pressure from the sensor to the control device and the actuator. Each sensor responds to changes in temperature, humidity, and static pressure as examples, to provide feedback in a control loop to open or close the actuator to meet the control set point. The actuators contain diaphragms and spring to function in sequence with the control signal. The prevalence of 25PSI based Pneumatic Building Control Systems that have been installed over many decades remain as a substantial and valid methodology within ICI (Industrial, Commercial, Institutional) facilities and as such require a specialized skill set to properly service and maintain these vital infrastructure systems.
Some might say Pneumatic building systems are old, obsolete, and a thing of the past. Well, we at Controls Central know that there are still a ton of building owners out there that want to keep their Pneumatic systems as they are, so we continue to stock a wide range of components. We have actuators, velocity controllers, thermostats, transducers, temperature controllers, and more to meet your needs. When it comes to Pneumatics, we don't just stick to one brand. We stock all of them, including KMC Controls, Honeywell, Johnson Controls, Schneider Electric, and Siemens. If you are looking for any of those hard-to-find Pneumatic Controls, we are your one-stop shop for everything Pneumatic.
In addition to the components mentioned, we also offer an extensive selection of other Pneumatic products.
