Johnson Controls A-4423-1 Air Dryer

The Johnson Controls A-4423-1 Air Dryer is a critical component for maintaining the integrity of pneumatic control systems by effectively removing moisture and preventing line freeze-ups. This refrigerated air dryer utilizes a hermetically sealed compressor and R-134a refrigerant to provide consistent compressed air treatment for building automation and HVAC controls. Operating on a standard 115 Vac power supply, it is designed for a 125 psig maximum input pressure and handles flows up to 23 scfm. The unit features 3/8" compression fittings, ensuring seamless integration with polytubing or copper tubing. Designed for heavy-duty industrial air purification, the A-4423-1 ensures that downstream actuators and controllers receive clean, dry air, preventing corrosion and reducing maintenance intervals on sensitive pneumatic devices. By maintaining a stable dew point, this unit protects the entire air distribution network from condensate-related failures in professional HVACR environments.
