Why Choose the Johnson Controls A-4417-1?
Moisture in pneumatic control air lines can cause corrosion, erratic valve operation, and costly system failures. The A-4417-1 refrigerated air dryer actively cools the compressed air supply to condense and remove water vapor before it reaches sensitive pneumatic controls, actuators, and valves. The hermetically sealed compressor eliminates refrigerant leak points, reducing maintenance demands and extending service life. With 3/8″ compression fittings, installation is straightforward with standard polytubing or copper tubing — no special adapters required. At 17 SCFM and a 125 PSIG maximum input pressure, this dryer is well-suited for medium-capacity pneumatic control networks in commercial buildings, industrial facilities, and institutional environments.
