📝 Product Overview

Our factory-direct CJC B27/27 replacement filter insert is a 1:1 precise alternative designed to fit perfectly into CJC offline oil filtration systems (such as the HDU series). Manufactured with high-density, multi-layered natural cellulose discs, this depth filter delivers the exact same performance and structural integrity as the original part but at a fraction of the cost.

Unlike standard online filters that only trap metal debris, our B27/27 alternative targets the three major oil killers simultaneously: micro-particles, water contamination, and oil oxidation products (varnish/sludge).

  APPLICATION The type B filter insert is manufactured specially for CJCTM Fine Filter units employed in the filtration of mineral and synthetic oil based

Motor lubricating oils 

Hydraulic oils 

Turbine lubricating oils

Gear oils Honing oils 

Rolling oils

🌟 Key Advantages & Features

• 1:1 Direct Interchangeability: Guarantees a seamless fit, matching the exact dimensions and sealing requirements of the OEM PA5601301 part.

• 3μm Absolute Filtration: Efficiently captures ultra-fine silt and abrasive particles to protect proportional valves and high-precision bearings.

• Superior Water Absorption: The natural cellulose material acts like a sponge, absorbing dissolved and free water from industrial oils.

• Varnish & Sludge Adsorption: Prevents valve sticking and system overheating by trapping sticky oil degradation products.

• Massive Dirt Holding Capacity: Deep filtration paths allow for high contaminant retention, leading to longer service life and extended oil drain intervals.
