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.   

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.
