Can I use a transfer cart to scrub the oil?

Transfer carts are designed to move oil quickly, but with speed comes a loss of filtration capability.  Typically transfer carts have nominal 10 micron to 15 micron filter.  The particles that are most likely to contaminate the valve on a hydraulic elevator are around 5 microns.  The Oil Scrubber™ has a 3 micron absolute filter and is over 98% efficient.
