HARVARD Filtration

HARVARD Filtration

In the early 1970s, the ever-increasing cost and complexity of engines and manufacturing machinery prompted the need for an improved system of filtration. Harvard Corporation was founded in April 1973 to meet that need. Then, as it is now, our mission was to develop, manufacture, and market the best filter and purification systems on the market. The Harvard® brand filter removes contaminants as small as one micron, filters synthetic and petroleum-based fluids, and removes the vast majority of silting particles. In addition, the filter absorbs water, antifreeze and other extraneous particles. Harvard Corporation also manufactures a line of filter elements to clean water-based fluids.

Partial-flow filtration of internal combustion engine lubricating oils was first applied in the days of inexpensive energy in the form of engine oils, gasoline, and diesel fuel. In those days, the cost of labor was relatively low in comparison with today. Originally, partial-flow filters were intended primarily to remove the harmful lubricating oil contaminants that endangered the operating life of engines to which they were applied. As time went on, partial-flow filtration was applied to hydraulic, transmission, and even brake fluids, as well as industrial in-plant applications with cutting oils, coolants and hydraulic fluids. A full line of power utilities fluid cleaning products has also been developed, including service trailers, LTC filter systems, and degas/dewater vacuum systems.

HARVARD Filtration Systemes

Filters Svstems Full-Flow Flilters: Designed to filter fast flowing oil, full-flow filters protect downstream components from larger size particulate matter. These filters typically hold particles from 20 to 40 microns in size. Their ability to pass large volumes of fluid makes full-flow filters unsuitable for smaller particles; without becoming large and expensive.
Partial-Flow Filters: Sometimes called a kidney loop, these filters are designed to filter a small stream of fluid; returning the filtered fluid to the sump of the system. These fĂ­lters typically hold particles from 1-10 microns. Smaller quantities of flow allow the filters to remove slighter particles without affecting the normal functions of the system.
