If I remember Milipore Steritop PVDF recommends max pressure 1bar(at) at 25*C(77*F) and maximal operating temp. 45*C(113*F) - max pressure not specified. So if you make 1bar underpressure and temp. 45*C I think filtration can be not effective. At higher temp. molecule oscillation will be higher and pressure will be pushing oil through loose pores so bigger particles will be passing to solution. At 25*C and 1 bar with SCGVT05RE is fast enough.
