Overview
Our excavator pilot hydraulic filter HR70002411 is a direct replacement for NEWTEC original filters, specially designed for Doosan & Daewoo DH, DX series excavators including DH150, DH215, DH220, DH225-7, DH225-9 and more models. We supply two filter versions to match different working conditions: perforated metal mesh reinforced filter and folded paper filter element.
Two Filter Types for Your Choice
Perforated Metal Shell Pilot Filter
Outer perforated steel plate provides solid protection for internal filter media. Adopts high-performance glass fiber composite material, featuring strong pressure resistance and impact resistance. Perfect for heavy-duty mining, harsh dusty construction sites with frequent hydraulic oil impact.
Folded Paper Pilot Filter
High-density engineering filter paper with folded structure expands filtration area greatly. Delivers superior precision to trap tiny metal debris, sludge and impurities inside hydraulic oil. Ideal for regular earthmoving and daily construction operation.
Core Functions
This small pilot filter serves the precise pilot control oil circuit of excavators. It effectively isolates fine contaminants in hydraulic oil to avoid spool sticking inside pilot valves and main control valves. It solves common equipment failures like heavy operation handles, slow movement response and weak compound actions, fully protecting expensive pilot pumps and hydraulic control components.
Service Life Recommendation
Standard replacement cycle: 500-1000 working hours.
For mining & high-dust environments: Replace every 500 working hours.
Immediate replacement is required once hydraulic oil turns black or operating handles become stiff.
