Alternative A Type Cellulose Filter Inserts
Overview
The FM A Type Cellulose Filter Inserts are high-performance replacement elements designed to fit CJC HDU fine filtration systems.
Manufactured from premium cellulose depth media, these filter inserts provide efficient removal of particles, water, varnish, sludge, oxidation products, and acidity from industrial oils.
Designed for low-viscosity and warm oil applications, the FM A Series offers excellent filtration efficiency, high contaminant holding capacity, and low operating costs, making it an ideal solution for maintaining hydraulic, lubrication, turbine, and industrial oil systems.
Key Features
4-in-1 Contamination Control
Unlike conventional particulate filters, FM A Type Filter Inserts remove four major contamination types simultaneously:
1. Solid Particles
• 3 μm absolute filtration
• Improves oil cleanliness levels
• Reduces component wear
• Extends equipment service life
2. Varnish & Oxidation Products
Effectively captures:
• Varnish
• Resin
• Sludge
• Oxidation residues
Benefits:
• Prevents sticky servo valves
• Reduces valve malfunction
• Eliminates surface lacquering
• Improves system reliability
3. Water Removal
The cellulose media absorbs free and emulsified water from oil.
Benefits:
• Prevents corrosion
• Reduces micro-pitting
• Inhibits bacterial growth
• Minimizes sludge formation
4. Acidity (TAN) Reduction
Removes acidic oxidation by-products that accelerate oil degradation.
Benefits:
• Extends oil service life
• Reduces equipment wear
• Slows oil ageing
• Improves lubricant performance
Superior Cellulose Depth Filtration Technology
FM A Type Filter Inserts utilize specially engineered cellulose depth media.
Features include:
• Deep-layer filtration structure
• High contaminant retention capacity
• Large effective filtration area
• Environmentally friendly natural cellulose fibers
• No plastic media
• No metal mesh
• No chemical additives
The bonded disc construction creates an extensive filtration surface area, allowing contaminants to be trapped throughout the media rather than only on the surface.
This results in longer service life and lower replacement frequency.
High Dirt Holding Capacity
The FM A Series offers exceptional contaminant holding capability.
Actual dirt holding capacity depends on:
• Particle size and shape
• Contamination type
• Oil condition
• System operating conditions
Compared with conventional surface filters, the depth filtration structure enables significantly higher contaminant retention before replacement is required.
Benefits include:
• Longer filter life
• Reduced maintenance frequency
• Lower operating costs
• Improved equipment reliability
