2 FILTER SIZING The correct filter sizing have to be based on the variable pressure drop depending by the application. For example, for the return filter the pressure drop have to be in the range bar. The pressure drop calculation is performed by adding together the value of the housing with the value of the filter. The pressure drop in the housing is proportional to the fluid density (kg/dm ); all the graphs in the catalogue are referred to mineral oil with density of 0.86 kg/dm. The filter pressure drop is proportional to its viscosity (mm /s), the corrective factor Y is related to an oil viscosity different than 0 mm /s. Sizing data for single cartridge, head at top pc = housing pressure drop [bar] pe = pressure drop [bar] Y = Multiplication factor Y (see correspondent table), depending on the filter size, on the filter lenght and on the filter media Q = flow rate (l/min) V reference viscosity = 0 mm /s (cst) V = operating viscosity in mm /s (cst) pe = Y : 000 x Q x (V/V) p Tot. = pc + pe Calculation examples with HLP Mineral oil Variation in viscosity Application data: Top tank return filter with inline connections Pressure Pmax = 0 bar Flow rate Q = 0 l/min Viscosity V = 6 mm /s (cst) Oil viscosity = 0.86 kg/dm Required filtration efficiency = 5 μm with absolute filtration With bypass valve and / inlet connection From the working pressure and the flow rate we understand it should be possible using the following top tank return filter series: MPT, MPH and FRI. Let s proceed with MPT series. The size 0 doesn t achieve the required flow rate, therefore we have to consider the size 00. The final version of size 00 (0, 0, 0, 0 and ) will be then defined in function of the mounting characteristics. pc = 0.0 bar ( see graphic below, considering size 00 with the max available lenght * to get the lowest pressure drop) pe = (.0 : 000) x 0 x (6/0) = 0.7 bar p Tot. = = 0. bar The selection is correct because the total pressure drop value is inside the admissible range for top tank return filters. It is of course possible trying to find a different solution, according to the mounting position or to other commercial need, repeating the previous steps while using a different series or lenght.
