AUTOMANN ADIS Type Air Dryer 12V Part No: 170.801266

The 170.801266 / ADIS Type Air Dryer 12V (Automann) is a complete air drying assembly designed for heavy duty trucks and commercial vehicles employing ADIS dryer architecture. It works by filtering out moisture, oil, and particulates from compressed air before that air enters brake and pneumatic systems, thus preventing internal corrosion or freezing. This dryer includes a 90W heater to prevent freeze in cold conditions, multiple ports for supply, delivery, and accessory connections, and precision internal valves calibrated at factory values. Automann’s version is built to match OEM performance, compatible with standard cross references, and supplied by Wofford Truck Parts with reliable support and fast shipping. Proper installation ensures safer, more stable braking performance and reduced maintenance costs across varied climates and operating conditions.
