Johnson Controls A-4412-1 Air Dryer

The Johnson Controls A-4412-1 is a high-capacity refrigerated air dryer designed for pneumatic control systems requiring a consistent supply of clean, dry air. Operating on a 115V single-phase power supply, this unit delivers a rated capacity of 12 SCFM, making it ideal for large-scale commercial HVAC automation setups. The A-4412-1 12SCFM dryer utilizes a robust refrigeration circuit to lower the compressed air dew point, effectively removing moisture that causes sensor contamination and actuator corrosion. For environments requiring higher air quality standards, this model supports an optional factory-mounted air purification system to eliminate oil aerosols and fine particulates. Its industrial-grade heat exchanger and hermetic compressor ensure reliable operation in high-demand mechanical rooms. When replacing an existing JCI pneumatic dryer, ensure your piping layout accounts for the unit's footprint and that the electrical circuit meets the specified FLA requirements for 115V service.

• 12 SCFM Capacity: Engineered to support large pneumatic logic networks and multiple control loops without pressure drop.
• 115V Configuration: Simplifies installation by utilizing standard voltage compatible with most mechanical room power panels.
• Moisture Removal: Maintains a low pressure dew point to prevent condensation and freezing in sensitive pneumatic lines.
• System Longevity: Protects pneumatic thermostats, relays, and dampers from moisture-related failures and scale buildup.
• Optional Purification: Available with integrated filtration for applications requiring oil-free and particulate-free air delivery.

What is the maximum inlet air temperature for the A-4412-1?
This unit is typically rated for an inlet temperature of 100°F (38°C). Exceeding this limit can reduce the drying efficiency and potentially trip the thermal overload on the compressor.

Does this model include a moisture separator and automatic drain?
Yes, the A-4412-1 features an integrated moisture separator and an automatic drain valve to ensure collected condensate is purged from the system without manual intervention.

Can the A-4412-1 be used with non-Johnson Controls pneumatic systems?
Absolutely. While designed for JCI systems, this 12 SCFM dryer is compatible with any pneumatic setup requiring clean, dry air, provided the CFM and pressure requirements align.
