Subject:
The Bendix Duraflo-596 Compressor has two features that we recommend
be considered carefully when maintenance is performed. The DF-596 is
designed to be naturally aspirated, unlike many compressors that use turbosupplied air. Also, the DF-596 uses an Energy Saving System (ESS)
unloader that requires a D-2 governor and an SV-1 synchro valve for
correct operation. Improperly configured systems may result in damage to
the compressor unloader. Damages caused by incorrect installation or nonnaturally aspirated applications are not covered under the warranty policy.
For ease of maintenance, Bendix provides a module for compressor-mount or
remote-mount applications with the special D-2 governor and SV-1 that the
DuraFlo-596 requires. If making individual repairs to the D-2 or SV-1, use
only genuine Bendix parts.
