The commonly held belief is that 80 percent of all hydraulic failures are due to  contaminated oil.  Oil delivered by drum, bulk truck, bucket and pail contains millions of particles too small to see but large enough to cause harm to your hydraulic systems.   A filter cart should be used to transfer the oil from the source to your reservoir.  A filter cart can also be used to clean up a system as a makeshift offline loop (Although we recommend a more permanent solution to this problem).
EHA makes several types of filter carts that can be used for different reasons such as water removal, fine polishing filtering, high speed transfer, particle counting, small hand held units, cooling/filtering units, and oil holding and transfer units.
EHA can use pneumatic driven transfer pumps for explosion-proof, mobile, or other environments where electricity is not available.
