Johnson Controls A-4423-2 Air Dryer

The Johnson Controls A-4423-2 is a professional-grade refrigerated air dryer designed specifically for pneumatic control systems in commercial and industrial HVACR environments. Engineered for continuous operation, this unit utilizes R-134a refrigerant within a hermetically sealed compressor circuit to effectively remove moisture from compressed air lines, preventing downstream corrosion and actuator failure. It handles a 125 psig maximum input pressure and delivers a rated capacity of 23 SCFM. The 115 Vac power requirement ensures compatibility with standard field power sources, while the 3/8" compression fittings allow for a secure, leak-proof interface with either copper or polytubing. For technicians managing compressed air treatment, the A-4423-2 provides the stability needed to maintain a constant pressure dew point, ensuring that pneumatic valves and thermostats receive dry, clean air for precise modulation. This industrial air dryer is a critical component for maintaining system longevity and optimal pneumatic system maintenance.
