Direct Back Return Line Filter (RF Series) – Versatile Mount for Industrial Hydraulic Filtration

A: The RF Series Direct Back Return Line Filter is a specialized filtration device for hydraulic systems. It fine-filters return oil to remove metal particles (from component wear) and rubber impurities (from seals), keeping oil clean as it flows back to the tank. It supports flexible installation (tank cover plate or pipe-mounted).

Flexible Installation: Can be mounted directly on the oil tank cover plate or via pipes, adapting to diverse hydraulic system layouts.

High-Efficiency Filtration: Uses glass fiber filter material, featuring:

High filtration accuracy (absolute rating: β≥3,5,10,20~100).

Large oil-passing capacity, small initial pressure loss, and large dirt-holding capacity.

Filtration efficiency ≥99% (compliant with ISO standards), ensuring thorough impurity removal.

It is exclusively used for fine filtration of return oil in hydraulic systems (e.g., industrial machinery, construction equipment hydraulic circuits), protecting system components by maintaining oil cleanliness and reducing wear.
