Working principle
OF controls oil-borne particles using glass-fiber media, with inside-to-outside flow in the available product record.
Construction & flow path
Match construction, ends and seating to the equipment. Confirm the meanings of rating, length and suffix codes individually.
Applications & filtration duty
For oil particle control. The oil-filter name does not establish dehydration, dissolved-substance removal or varnish-removal capability.
Technical parameters
Use these specifications for selection. Materials, dimensions and operating conditions follow the selected model and agreed specification.
Materials & construction
- Filter media
Glass-fiber filter membrane
- Construction & fabrication
Coreless, compact pleated construction.
- Seal-material codes
Ethylene-propylene rubber; suffix Z in this series must not be assigned the Z=NBR meaning used by other series.
Filtration specifications
- Filtration ratings
AZ=3 / AP=5 / AN=7 / AS=12 / AT=22 / AW=50 / AQ=75 / AY=100 μm
- Nominal length
20 / 40 in
Operation & maintenance
- Operating temperature
−29 to 120 °C
- Recommended replacement differential pressure
Change-out differential-pressure reference: 3.5 bar; establish replacement conditions for the fluid, temperature and system requirements.
- Cartridge collapse pressure
Cartridge collapse-pressure reference: 10 bar; review conditions for the selected cartridge, separately from housing operating pressure.
- Flow direction
Inside to outside
Selection information
- Outside / inside diameters

Information to prepare for an inquiry
Use this family’s selection priorities to share available operating conditions, equipment information or drawings.
- Provide oil type, viscosity, temperature and cleanliness target.
- Check equipment model, fit dimensions and inside-out flow.
- Provide the complete model for orders or replacements to check the ending code and compatible specification.
Operation & maintenance
Interpret pressure drop with oil temperature and viscosity, and check flow direction, retention and seals. Replace around cleanliness targets and pressure drop.
Common operating inputs
- Fluid and major composition
- Target flow and operating pattern
- Operating temperature and pressure
- Contaminant form and target rating
- Material, connection and space constraints
- Maintenance frequency and existing equipment
