Filter element pressure drop curve
The pressure drop characteristic curve of the filter element is suitable for mineral oil with a kinematic viscosity of 30mm²/s, and the pressure drop changes in proportion to the viscosity。
Selection example
公式
ΔP total = ΔP shell + ΔP filter element × (viscosity mm²/S÷30mm²/S)
举例：
Flow 300L/min, accuracy 10u, 46# hydraulic oil
Selection VKCH660
ΔP shell=0.55bar, ΔP filter element=0.35×(46mm²/S÷30mm²/S)=0.54
ΔP总==0.55+0.54=1.09bar
