Core Operational Benefits
Protecting the high-pressure fuel pump and injectors is vital for longevity. This filter ensures:
Micro-Particle Interception: Captures ultra-fine dust, metallic shavings, and fuel gums.
Moisture Elimination: Prevents injector rusting, engine misfires, and white smoke.
System Reliability: Specially calibrated for Deutz engine flow requirements to reduce repair costs.
Machine Compatibility
Essential for SANY excavators with Deutz engine architectures (typically -9 and -10 series):
Supported Models: SY195C, SY205C, SY215C, SY225C, SY235C, SY245H, SY265C, SY365C, SY365H.
Maintenance & Professional Installation
Installation Best Practices:
Depressurize: Relieve fuel line pressure to prevent spray.
Pre-Fill: Fill the new filter with clean diesel fuel before installation to prevent airlocks.
Gasket Change: Always use the new fluororubber gasket; never reuse old components.
Schedule: Replace every 2000 hours (or 1000–1500 hours in severe/mining conditions).
