Description
The Johnson Controls A-4412-1 is a refrigerated air dryer engineered specifically for pneumatic control systems, delivering clean, dry instrument-quality air to protect sensitive controls and extend system life. Featuring a hermetically sealed refrigeration circuit charged with R-134a refrigerant, this unit provides reliable moisture removal without the risk of refrigerant leaks or the need for compressor oil maintenance.
Key Features
- Designed for pneumatic control system air supply applications
- Hermetically sealed refrigeration circuit for leak-free, maintenance-friendly operation
- R-134a refrigerant — environmentally responsible and widely available
- 115 VAC power supply for standard single-phase electrical connections
- 125 PSIG maximum input pressure rating
- 12 SCFM airflow capacity to support a range of pneumatic control loads
- 3/8″ compression fittings compatible with both polytubing and copper tubing
- Integrated air purification system removes moisture, oil aerosols, and particulates
Why Dry Air Matters in Pneumatic Control Systems
Moisture-laden compressed air is one of the leading causes of pneumatic control system failures. Water in the air supply corrodes actuators, clogs orifices, and causes erratic control behavior. The A-4412-1 refrigerates the incoming air stream to condense and drain moisture before it can reach downstream controls, ensuring consistent, accurate pneumatic signal transmission.
