7621890 Premium Hydraulic Filter
Product Description
7621890 premium hydraulic filter engineered to capture harmful particulates, maintaining high fluid cleanliness and reducing critical component wear. Serving as a direct OE replacement for Liebherr and HiFi Filter systems, it features a robust structural casing for reliable, leak-free operation under demanding operating conditions.
Working Principle
- ▪ Fluid Ingress: Contaminated hydraulic oil enters the filter housing and surrounds the outer surface of the pleated filter media.
- ▪ Micro-Filtration Barrier: Fluid forces through multi-layered mesh media, trapping harmful solid particles, wear debris, and contaminants on the outer surface.
- ▪ Clean Oil Return: Purified hydraulic fluid flows into the inner core tube and returns back into the system circuit to maintain optimal pressure and component protection.
