Harvard’s® innovative flow-through filtration systems route oil-flow from the top and bottom of the filter element, through the media to the collector, to the center tube, and out of the canister. As the oil moves through the media, it loses pressure while the exterior of the element remains constant, causing a slight funnel-shape deformation in which larger particles are caught at the top and smaller particles are retained in the lower area, where the funnel is smaller. This filtration process allows the filter to hold larger quantities of contaminants in comparison to surface media filters.
Since the media is designed with a dehydrated media it is also effective in removing moisture, enabling the particles and moisture to be removed with the same filter. However, in situations where moisture is not to be removed, an appropriate media may be used to remove solid contaminants only.

While not as common as oil, fuel and hydraulic filtration, coolant filtration has been a growing technology in recent years.
Without effective filtration, fuel tanks and fuel systems have always been a haven for the collection of contaminants and moisture.
