Description
The Johnson Controls A-4423-1 is a high-performance refrigerated air dryer engineered specifically for pneumatic control systems. By removing moisture from compressed air before it reaches sensitive pneumatic controls, this unit protects downstream equipment from corrosion, freezing, and premature wear — ensuring reliable, consistent system operation in commercial and industrial HVAC environments.
Key Features
- Designed for use with pneumatic control systems
- Hermetically sealed refrigeration compressor for quiet, maintenance-free operation
- Uses R-134a refrigerant — an environmentally responsible choice
- 115 VAC power supply for easy integration into standard electrical systems
- Maximum input pressure rating of 125 PSIG
- 23 SCFM airflow capacity to handle demanding pneumatic system loads
- 3/8″ compression fittings compatible with both polytubing and copper tubing
- Functions as a complete air purification system, removing moisture and contaminants
Why Use a Refrigerated Air Dryer?
Moisture in compressed air lines is a leading cause of pneumatic control failures. The A-4423-1 refrigerates incoming compressed air to condense and drain water vapor before it can reach actuators, valves, and controllers. The result is cleaner, drier air that extends the life of your pneumatic components and reduces costly downtime.
