3.2 Technical Data

  Note: * represents filtration rating.

4. Mounting Size

5.  Product characteristic curves           

The total filter assembly pressure drop is the sum of housing and element pressure drop,filter selection calculated as per the following curves.

5.1 Housing pressure drop / flow rate characteristic curves 

Housing pressure drop /flow rate characteristic curves are according to ISO3968, and suitable for the mineral oil with density 0.86 kg/dm³ and kinematic viscosity 30 mm²/s. 

                       Filter housing pressure drop

5.2 Differential pressure / flow characteristic curves of filter element

The characteristic curves of filter element are suitable for the mineral oil with kinematic viscosity 30 mm²/s. Differential pressure and viscosity is proportional.

                    Clean filter element pressure drop
