Abstract:
A transmission oil filter has a filtration layer of fiberglass medium and, downstream of the filtration layer, a melt blown layer applied to the filtration layer for preventing or reducing introduction of fiberglass into the liquid to be filtered. The filtration layer of fiber glass medium has two faces and a spunbond layer is attached for improved handling of the filtration layer of fiberglass medium to at least one of the two faces.
