|Air Dryers

What can be done to prevent air from leaking constantly from the drain discharge part of an IDF□□E or IDU□E series air dryer with an auto drain?

Clean the inside of the case assembly with neutral detergent dissolved in water. Flush the drain discharge section (flushing and air blowing).
If the auto drain malfunction still persists, replace the auto drain.
For details, refer to the operation manuals of each air dryer series.
IDF□E and IDU□E series air dryers produced from March 2019 (or June 2019) onward feature the new auto drain with a different part number and shape.
