A-4400 Series Refrigerated Air Dryers for Pneumatic Control Systems
Code No. LIT-1921105
Issued December 23, 2013
Description
The A-4400 Series Refrigerated Air Dryers are
designed for continuous operation to supply
dry air to pneumatic control systems. All
components are selected and assembled to
provide dependable service over a long period
of time with a minimum amount of
maintenance. The air dryer uses R-134a
refrigerant, an environmentally friendly HFC,
minimizing the risks and/or costs associated
with use and disposal of refrigerants.
There are six models available, models can be
ordered with or without an optional factory
mounted Air Purification System. For air dryers
not equipped with an optional factory mounted
Air Purification System, a properly configured
air supply system must include a coalescing oil
removal filter as well as an activated carbon oil
vapor removal filter.
Refer to the A-4400 Series Refrigerated Air
Dryers for Pneumatic Control Systems
Product Bulletin (LIT-718050P) for important
product application information.
