Why Choose the Johnson Controls A-4423-2?
Moisture in compressed air lines is one of the leading causes of pneumatic control system failures, causing corrosion, erratic valve operation, and costly downtime. The A-4423-2 refrigerates the incoming air stream to condense and remove water vapor before it can reach sensitive actuators, controllers, and instrumentation. The result is a cleaner, drier air supply that extends equipment life and improves system reliability. With its hermetically sealed design, 115 VAC operation, and straightforward 3/8″ compression fittings, this unit installs quickly and operates with minimal ongoing maintenance — making it an ideal solution for building automation, industrial process control, and HVAC pneumatic networks.
