In all actuality, pneumatic systems are simply a division of engineering which uses gas or pressurized air. Pneumatic control systems can be effective and economical. In HVAC systems, this control method relies on sensors and thermostats that retain the line pressure from the sensor to the control device and the actuator. This course will provide a basic understanding of the components that make up a pneumatic system including the conditioning and operating systems. An introduction to pneumatic actuators, electro-pneumatic transducers, and pneumatic thermostats is included. Additionally, you'll learn about certain hazards associated with maintaining a pneumatic system and the proper safety precautions and maintenance techniques that will minimize these hazards.
