Appendix III Special Applications
Holset E-Type Compressor
Systems
When a System Saver Series air dryer is used with
a Holset E-type compressor system, an external
Econ valve is used.
Figure A.1 .
On the 1200E Series, an integral Econ function
eliminates the need for the external Econ valve.
Figure A.2 .
If you are currently using a System Saver Series
air dryer WITHOUT an Econ valve, and your
application requires one, Meritor WABCO
recommends installing the System Saver 1200E.
