Hydraulic Oil Filter Elements – Models 7110337807400 & 7212302080124

Two high-performance hydraulic and lubrication oil filter elements from the same industrial filtration family, designed for oil-filter circuits on compressors, hydraulic power units, and heavy machinery. 7110337807400 is an oil filter element (10–15 µm glass-fiber media) originally specified for screw compressor lube circuits and hydraulic oil-conditioning loops . 7212302080124 is the companion element in the same performance family (listed as both an oil-mist separator for compressors and a hydraulic oil filter cartridge) — configurable to the host machine's housing envelope, micron requirement, and pressure class . Both use imported glass-fiber media qualified to ISO 16889 multi-pass testing, delivering 98 % filtration efficiency, 2000 h service life, and high dirt-holding capacity .

Key Features

• 7110337807400: Glass-fiber media, 10–15 µm, 98 % efficiency, 2000 h service life, 0–100 °C operating range

• Both: imported glass-fiber media — high tensile strength, corrosion-resistant, non-combustible

  
  

• Gradient-density pleated structure for high dirt-holding and low initial ΔP

  
  

• End caps: carbon steel, stainless steel, aluminum, or nylon

  
  

• NBR seals standard; FKM optional for high-temperature or synthetic-fluid circuits

  
  

• Bypass valve optional per housing configuration

  
  

Technical Specifications

Exact OD, length, and seal interface are configured per host machine housing — confirm against your existing element before ordering.

Application Guidance

7110337807400 – Installed in the oil circuit of rotary screw compressors and hydraulic power units. The 10–15 µm glass-fiber media removes metallic wear particles and mechanical impurities, maintaining oil cleanliness to extend bearing, gear, and rotating-component life. The 2000 h service interval  aligns with standard compressor lube-oil change schedules.

7212302080124 – A versatile element deployed across two duties: (1) as an oil-mist separator in compressor air-oil separation chambers, and (2) as a hydraulic oil filter cartridge with configurable micron grade (1 µm for servo-valve protection, 200 µm for coarse suction pre-filtration) . The 21–210 bar collapse pressure  makes it suitable for both return-line and pressure-line hydraulic positions.

💡 Functional distinction: 7110337807400 is primarily a particulate oil filter (solid contaminant removal from liquid oil); 7212302080124 performs both phase separation (oil mist from gas) and particulate filtration depending on housing. They are not directly interchangeable — confirm your housing type and circuit position before selecting.

Fluid Compatibility

• Mineral hydraulic oil (ISO HM, HV)

  
  

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

  
  

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

  
  

• HFC water-glycol — NBR acceptable; FKM recommended

  
  

• Phosphate ester (HFDR) — FKM seals + compatible media required

  
  

• Not for strong solvents or corrosive chemicals

  
  

Installation & Service

1. Shut down the compressor/hydraulic unit; relieve pressure to 0 bar and isolate the filter housing.

   
   

2. Drain oil from the housing — place a collector beneath before opening .

   
   

3. Withdraw the spent element by its center tube — never strike, drop, or pry; the media pack is precision-formed.

   
   

4. Inspect housing interior, bypass spring (if fitted), and seal grooves.

   
   

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

   
   

6. Close the housing, torque bolts evenly. Ramp pressure up gradually — do not instantaneously open to full working pressure .

   
   

7. Replace per 2000 h service interval  or when ΔP reaches the clogging threshold.

   
   

⚠️ Filter elements are consumables. During removal, avoid scratching, impact, or striking — never apply direct force to the element surface with tools. Reverse filtration (inside → outside) is not recommended.

Quality Assurance

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

  
  

• ISO 2941 – collapse/burst resistance (21–210 bar)

  
  

• 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 – pressure drop vs. flow-rate characteristics

  
  

Ordering

Specify 7110337807400 (oil filter element, 10–15 µm glass-fiber, 2000 h service life) with:

• Seal material (NBR / FKM)

  
  

Specify 7212302080124 with:

• Required micron rating (1–200 µm)

  
  

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

  
  

• Seal material (NBR / FKM)

  
  

• End cap material (carbon steel / stainless steel / aluminum / nylon)

  
  

• 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; 7110337807400 is specified at 10–15 µm, 98 % efficiency, 2000 h life, 0–100 °C . 7212302080124 dimensional envelope and micron grade are configurable per housing pattern — confirm against your current element or housing drawing before installation . Select micron grade to match circuit position: 3–5 µm for servo valves, 10 µm for piston pumps, 10–20 µm for vane/gear pumps, 20–40 µm for return loops and coarse pre-filtration. Too fine on suction accerates clogging; too coarse on servo circuits leaves precision components under-protected.
