desiccant regeneration

compressor
E Indicates a Holset style compressor function
G Indicates integral governor for air compressor
control
UP Indicates discharge line — unloaded
compressor (with external purge tank)

System Saver 1200E: Tubing and banjo fitting at
front of dryer
System Saver 1200P/1800P: Uses dedicated purge

The air dryer base is the same for both the 1200
and 1800 Series air dryers, however the 1800
Series canister is 3.2 inches taller than the 1200.
This larger canister contains 50% more desiccant,
which makes the 1800 ideal for applications calling
for frequent starts, stops and long compressor
cycles. System Saver 1200 and System Saver 1800
Series air dryers are illustrated in
Figure 1.1 .
System Saver 1200P and System Saver 1800P,
