Hydraulic & Lubrication Oil Filter Elements – Models M20-010P & A08-010P

Two folded (pleated) filter elements from the same industrial filter family, engineered for hydraulic pressure-line, return-line, suction-line, and lubrication-circuit duties across power-generation plants, steel mills, shipboard lubrication systems, injection molding machines, compressor lube circuits, and mobile hydraulic equipment. The model coding defines both elements: "010" = 10 µm filtration accuracy, "P" = paper / glass-fiber media — a disposable, deep-bed filtration layer that captures fine particulate while maintaining low initial differential pressure . M20-010P is the larger-format element of the pair, matched to the M20 / VLM20-class filter housing for higher flow volumes . A08-010P is the compact companion, engineered for A08-standard filter housings with Rc3/4 interface, widely deployed on marine lube oil systems, machine tool hydraulic stations, and low-pressure suction circuits . Both remove solid contaminants from oil circuits, protecting pumps, servo valves, bearings, and precision components from abrasive wear.

Key Features

• M20-010P: Folded pleated cartridge, glass-fiber or filter-paper media, 10 µm grade, matched to M20 / VLM20-class housing, stainless or carbon steel core, NBR/FKM seal

  
  

• A08-010P: Folded pleated cartridge, glass-fiber media, 10 µm grade, A08 standard specification, Rc3/4 interface filter housing, integrated 0.5 MPa bypass valve, NBR seal rated -20 °C to +100 °C

  
  

• Both: "010" = 10 µm, "P" = paper/glass-fiber media per MASUDA coding rules

  
  

• Deep-bed filtration layer — captures fine ferrous debris, dust, and wear particles; high dirt-holding capacity extends service interval

  
  

• Low initial differential pressure — minimizes pump suction load, prevents cavitation and erosion damage

  
  

• Folded construction maximizes effective filtration area in compact envelope

  
  

• Disposable media — replace, do not attempt to clean

  
  

• Complete ISO test suite: ISO 2941 / 2942 / 2943 / 3723 / 3724 / 3968 / 4572 / 16889

  
  

Technical Specifications

* Exact OD, length, ID, and end-cap pattern are defined by the mating M20 / A08 filter housing — confirm against your existing element before ordering.

Application Guidance

M20-010P – Higher-flow folded element for pressure-line, return-line, and lubrication-circuit filtration on heavy industrial equipment:

• Rolling mill and continuous caster hydraulic stands

  
  

• Power plant turbine lube oil and jacking oil systems

  
  

• Large injection molding machines and die-casting equipment

  
  

• Mining machinery hydraulic power units

  
  

• Shield machine (TBM) hydraulic circuits

  
  

The 10 µm glass-fiber/paper media delivers fine particulate control while the larger M20 envelope sustains high flow rates without excessive differential pressure. Configurable to 1–70 µm (glass-fiber) or 5–40 µm (paper) per application .

A08-010P – Compact folded element for low-pressure suction and lube oil filtration:

• Marine lubrication systems (shipboard diesel engines, gearboxes, thrusters)

  
  

• Machine tool hydraulic stations and general industrial hydraulic power units

  
  

• Wind-power turbine lubrication auxiliary circuits

  
  

• Paper machinery, textile equipment, and compressor lube loops

  
  

• Low-pressure dual-switch suction pipelines

  
  

The A08-010P is particularly suited to mineral oil hydraulic systems with moderate contamination load and limited budget — the glass-fiber pleated media provides stable 10 µm filtration at low initial differential pressure, while the integrated 0.5 MPa bypass valve prevents pump cavitation if the element clogs .

📌 Coding rule: In this filter family, "010" always denotes 10 µm filtration accuracy, and "P" denotes paper/glass-fiber disposable media (compare: "AN" = aluminum notch-wire, "SW" = stainless steel wire mesh — both reusable) . When ordering replacements, confirm the housing class (M20 vs A08) — they are not dimensionally interchangeable despite sharing the 010P media grade.

Fluid Compatibility

• Mineral hydraulic oil (ISO HM, HV, HH, HL)

  
  

• Mineral turbine / gear / compressor / bearing lube oil

  
  

• Phosphate-ester hydraulic fluid (HFDR) — FKM seals required

  
  

• Emulsions and water-glycol (HFC) — NBR acceptable; FKM recommended

  
  

• Biodegradable esters (HEES, HETG) — FKM recommended

  
  

Installation & Service

1. Shut down the equipment; relieve system pressure to 0 bar and isolate the filter housing.

   
   

2. Open the housing cover, withdraw the spent cartridge by its center tube or tie rod.

   
   

3. Inspect the housing interior, bypass spring, and seal grooves.

   
   

4. Seat the new element — confirm flow direction (Outside → Inside). Renew all O-rings / seals.

   
   

5. Close the housing, torque bolts evenly. Bleed air at the bleed port.

   
   

6. Restart and gradually ramp up to working pressure — never open the valve instantly to full flow.

   
   

7. Replace per clogging indicator (visual 3-color or ΔP alarm) or service interval. Typical replacement: 1000–2000 operating hours in moderate contamination; 250–500 hours in foundry, mining, or marine heavy-duty environments.

   
   

8. Paper/glass-fiber elements are disposable — never attempt to clean; only metal-mesh (AN/SW) media can be washed and reused.

   
   

9. When withdrawing the spent element, inspect for metal particles — copper or iron debris indicates pump/valve damage; rubber fragments signal seal failure.

   
   

⚠️ A clogged element left in service triggers the bypass valve, allowing unfiltered oil to circulate — the primary cause of over 70 % of hydraulic system failures. Monitor the clogging indicator and replace proactively.

Ordering

Specify M20-010P (M20/VLM20-class, 10 µm P-media) with:

• Media type (glass-fiber / filter paper)

  
  

• Micron grade (1–70 µm BF / 5–40 µm paper)

  
  

• Seal material (NBR / FKM)

  
  

• Fluid code (blank = mineral oil / W = water-glycol / F = phosphate ester)

  
  

Specify A08-010P (A08-standard, Rc3/4, 10 µm glass-fiber) with:

• Micron grade (10 / 50 µm per application)

  
  

• Seal material (NBR standard)

  
  

• Fluid code (blank / W / F)

  
  

Provide your existing element's dimensions or the host filter housing model and current OEM part number for cross-reference confirmation. Custom media grades and end-cap configurations are available on request.
