Johnson Controls A-4417-1 Air Dryer

The Johnson Controls A-4417-1 Air Dryer is a critical component for maintaining the integrity of pneumatic control systems by effectively removing moisture from compressed air lines. Operating on a 115 Vac power supply, this refrigerated air dryer utilizes an R-134a refrigerant circuit within a hermetically sealed compressor to ensure consistent dew point suppression. Designed for high-demand industrial environments, the unit supports a 17 SCFM air flow capacity and handles a 125 PSIG maximum input pressure. The 3/8 inch compression fittings facilitate a direct, secure interface with both copper tubing and polytubing. By preventing condensation and subsequent corrosion or freezing within instrumentation lines, the A-4417-1 ensures the longevity of downstream actuators and controllers. This air purification system is the standard for contractors requiring reliable moisture remediation in sensitive pneumatic loops.

• 17 SCFM Capacity: Engineered to handle high-volume air flow requirements in multi-zone pneumatic networks.
• Maintenance-Free Compressor: The hermetically sealed design prevents refrigerant leaks and internal contamination.
• Standardized Fittings: Integrated 3/8 inch compression fittings simplify the installation process on existing pneumatic control systems.
• R-134a Refrigerant: Utilizes a standard, non-ozone-depleting refrigerant for stable thermal exchange.
• System Protection: Minimizes downtime by eliminating moisture-related sticking in sensitive pneumatic valves.

What is the maximum inlet pressure for the A-4417-1?
The unit is rated for a 125 PSIG maximum input pressure, making it compatible with most standard commercial air compressors used in HVAC automation.

Can this dryer be used with plastic tubing?
Yes, the 3/8" compression fittings are designed to provide a leak-proof seal for both copper and polytubing, common in refrigerated air dryer retrofits.

Is the refrigeration system serviceable?
The unit features a hermetically sealed cooling system designed for long-term operation without the need for frequent refrigerant recharging.
