Why Choose the Johnson Controls A-4412-2?
Moisture in pneumatic control air lines is one of the leading causes of system failure, valve damage, and erratic control behavior. The A-4412-2 refrigerates the incoming compressed air to condense and remove water vapor before it can reach sensitive pneumatic controls. The result is cleaner, drier instrument air that extends equipment life and improves system reliability. With 3/8″ compression fittings accepting both polytubing and copper tubing, installation is straightforward and adaptable to existing infrastructure.
