Hydraulic Oil Filter Elements – Models F00611000, F00611020 & F00611030

Three high-performance hydraulic oil filter elements from the same F006-series industrial filter family, designed for return-line, pressure-line, and bypass filtration on hydraulic power units, injection molding machines, compressor lube circuits, and mobile equipment. All three use glass-fiber composite media qualified to ISO 16889 multi-pass testing, with gradient-density construction for high dirt-holding capacity and low initial differential pressure. The numeric suffixes denote different dimensional or performance grades within the same housing envelope — confirming the exact OD, length, and seal interface against your existing element is required at time of order.

Key Features

• Glass-fiber composite media, 1–25 µm selectable per suffix (β₁₀ ≥ 200 typical)

  
  

• Gradient-density structure for stable β-ratio throughout service life

  
  

• Perforated steel center tube, collapse pressure up to 210 bar (pressure-line trim)

  
  

• NBR seals standard (−30 °C to +100 °C); FKM optional for high-temperature or ester-fluid circuits

  
  

• Bypass valve optional per housing configuration

  
  

• Flow direction outside → inside (standard for pressure/return elements)

  
  

Technical Specifications

Exact OD, length, and seal interface differ between suffixes — confirm against your current element before ordering.

Application Guidance

All three elements serve pressure-line, return-line, and bypass duties on hydraulic power units, injection molding machines, press brakes, compressor lube circuits, and mobile excavator/loader hydraulics. The glass-fiber media geometry is engineered to maximize dirt-holding capacity while maintaining stable β-ratio performance throughout the service life.

Selecting between F00611000, F00611020, and F00611030 depends on:

• Available housing space (element length)

  
  

• Required dirt-holding capacity (longer element → longer service interval)

  
  

• Flow rate (higher flow → larger element / higher β-rating)

  
  

Micron grade should match circuit position:

• Pressure-line / servo valves: 1–5 µm

  
  

• Return line / general hydraulic: 10–15 µm

  
  

• Suction or pre-filtration: 20–25 µm

  
  

⚠️ Verify the bypass valve setting matches your housing — an incorrectly calibrated element allows unfiltered oil to circulate, causing component wear. Always confirm dimensions and connection type: even small differences in size or thread cause leaks.

Fluid Compatibility

• Mineral hydraulic oil (ISO HM, HV)

  
  

• Mineral turbine / gear / compressor oil (lubrication duty)

  
  

• Biodegradable esters (HEES, HETG) — use FKM seals

  
  

• HFC water-glycol — NBR acceptable; FKM recommended

  
  

• Not for phosphate ester (HFDR) without media/seal confirmation

  
  

Installation & Service

1. Turn off the equipment and power; close the oil inlet valve.

   
   

2. Open the drain port at the bottom of the filter housing and the vent at the top; discharge the oil cleanly.

   
   

3. Open the upper cover, remove the old element by its center tube, and clean all filter surfaces.

   
   

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

   
   

5. Seat the new element — confirm flow direction arrow (outside → inside). Renew all O-rings / seals.

   
   

6. Close the cover, torque bolts evenly in cross pattern. Bleed air at the bleed port.

   
   

7. Restart and check for leaks at operating pressure.

   
   

8. Replace per clogging indicator or 2000–4000 h service interval (depends on micron grade and contamination load).

   
   

Quality Assurance

• ISO 16889 – multi-pass filtration performance (β-ratio, dirt capacity, ΔP)

  
  

• ISO 2941 – collapse/burst resistance

  
  

• ISO 2942 – manufacturing integrity (bubble point)

  
  

• ISO 2943 – media/fluid compatibility

  
  

• ISO 3723 – end-load compliance

  
  

• ISO 3724 – flow fatigue under cyclic differential pressure

  
  

• ISO 3968 – differential pressure vs. flow-rate characteristics

  
  

Ordering

Specify F00611000, F00611020, or F00611030 together with:

• Required micron rating (1 / 3 / 5 / 10 / 20 / 25 µm)

  
  

• Collapse pressure class (21 / 60 / 160 / 210 bar)

  
  

• Seal material (NBR / FKM)

  
  

• Bypass configuration (with / without)

  
  

• Mounting details (OD, length, seal interface of your current element)

  
  

Provide your existing element's dimensions or the host machine model and current OEM part number for cross-reference confirmation.

All values nominal; the precise OD, length, and seal interface geometry differ between suffixes. Confirm against your current element or housing drawing before installation — select micron grade to match circuit position: too fine on suction/pre-filtration accelerates clogging; too coarse on servo circuits leaves precision components under-protected.
