A19AAF-21C Johnson Controls Temperature Control

Overview

The Johnson Controls A-4412-2 is a Series A-4400 refrigerated air dryer engineered for continuous operation to supply dry air to pneumatic control systems. By refrigerating incoming compressed air to condense and remove water vapor, this unit protects downstream pneumatic controls, actuators, and instruments from corrosion, freeze-ups, and performance degradation. It features a robust, low-maintenance design without a factory-mounted air purification system.

Features

• Hermetically sealed refrigeration compressor for long service life and minimal maintenance.
• Environmentally friendly R-134a HFC refrigerant to minimize risks and disposal costs.
• Internally mounted evaporator pressure gauge and automatic condensate drain trap with a particle filter.
• Removable protective cover and an insulating sleeve that slips over the drain trap to eliminate external condensation.
• Standard cord and plug for easy connection to electrical service.

Specifications

• Air Flow Capacity: 12 SCFM (5.7 L/s) at rated conditions
• Maximum Input Pressure: 125 PSIG (862 kPa)
• Electrical Rating: 115 VAC, 60 Hz, single-phase, 5.75 Amps
• Connections: 3/8 inch compression fittings for polytubing or copper tubing
• Operating Temperature Limits: 40 to 115 degrees Fahrenheit (4 to 46 degrees Celsius)
• Dimensions: 28 x 15 x 17 inches
• Weight: 65 lbs

Applications

• Commercial and industrial HVAC pneumatic control systems.
• Clean air supply setups requiring moisture removal to prevent system failure and ensure consistent signal transmission.
