Johnson Controls A-4412-2 Air Dryer

For mission-critical pneumatic control systems, the Johnson Controls A-4412-2 provides reliable refrigeration-based moisture removal to prevent instrument drift and equipment corrosion. This compact refrigerated air dryer is engineered for continuous duty, delivering a clean air supply with a 12 SCFM flow capacity at rated conditions. Built with a hermetically sealed compressor and high-efficiency heat exchanger, the unit utilizes R-134a refrigerant to meet modern environmental standards while maintaining a steady 35°F to 39°F pressure dew point. Designed for industrial 115 Vac single-phase electrical service, it features 3/8" compression fittings for seamless integration with copper or polytubing. The Johnson Controls A-4412-2 includes an automatic condensate drain trap with a particle filter, protected by an insulating sleeve to eliminate external sweating. For contractors managing pneumatic control systems, this dryer is a standard-tier solution for ensuring long-term stability and reducing maintenance overhead in high-demand HVACR environments.

• Continuous Duty Performance: Engineered for 24/7 operation to protect sensitive pneumatic instruments from moisture-related failures.
• Compact Footprint: Ideal for tight mechanical rooms or space-constrained mounting near the air compressor.
• Internal Maintenance Access: The evaporator pressure gauge and automatic drain trap are internally mounted but easily accessible through the end of the unit.
• Moisture Prevention: Effectively removes water vapor to stop line corrosion and prevent freezing in outdoor pneumatic lines.
• Environmental Compliance: Uses non-ozone depleting R-134a refrigerant, simplifying future service and disposal requirements.

What is the maximum inlet pressure for the A-4412-2?
The unit is rated for a 125 psig maximum input pressure, making it compatible with most standard industrial air compressors.

Does this model include a factory-mounted air purification system?
No, the A-4412-2 is the version without the optional factory-mounted air purification system. For systems requiring oil removal, a separate coalescing filter and activated carbon filter should be installed upstream.

Can this unit be hardwired?
Yes. While it comes with a standard 115V cord and plug, the cord is removable to allow for permanent conduit wiring if required by local electrical codes.
