Ameroid CJC Offline Filter – Depth Filtration for Ultra-Clean Industrial Oils

Welcome to Nichiboku's industrial Blog

Keeping hydraulic, lubricating, and insulating oils cleaner for longer Introduction

In today’s demanding industrial environments, oil cleanliness is no longer just a maintenance goal — it’s a performance standard. Contaminated hydraulic or lubricating oil can quickly lead to valve sticking, component wear, and unexpected downtime.

The Ameroid CJC Offline Filter, designed with depth filtration technology, offers a powerful solution to maintain superior oil purity. Built for hydraulic, lubricating, insulating, cleaning, and rust-preventive oils, this system helps extend equipment life, reduce oil changes, and ensure operational reliability — key priorities for modern factories and maintenance teams.

The Ameroid CJC Offline Filter offers advanced depth filtration for superior oil cleanliness, ideal for hydraulic and lubrication systems.

How Depth Filtration Works

Unlike surface filters that trap only larger particles on the outer layer, depth filtration captures contaminants throughout multiple layers of the filter element.

The Ameroid CJC Offline Filter uses a high-density cellulose filter medium that removes both solid particles and absorbed water from the oil. Its absolute 3 µm filtration accuracy ensures a stable cleanliness level equivalent to ISO 16/14/11 (NAS 5 class) — ideal for sensitive hydraulic and lubrication systems.

This deep filtration approach enables:

• Longer filter life

• Higher contamination retention

• Stable performance under continuous operation
  

Features of the Ameroid CJC Offline Filter

• Uses a depth filtration filter element that captures impurities not only on the surface but also inside.

• Compatible with mineral oil-based as well as ester-based and water-glycol-based fire-resistant hydraulic oils.

• Filters out foreign matter and absorbs water.

• Operates offline — filtration possible even when equipment is stopped.

• Wide range of models available, from tanks under 100 L to systems exceeding 100,000 L.
  

Purpose of the Ameroid CJC Offline Filter

• Purification of hydraulic oil, lubricating oil, cleaning oil, rust-preventive oil, and insulating oil.

• Suitable for reclaiming used oil and extending oil life cycles.
