NBF
The Eaton breather filters of the NBF Series “breathe” air in and out as the oil level rises and falls. The filters prevent the penetration of contamination from the ambient air in the hydraulic fluid.
EBF
The Eaton breather filters of the EBF Series “breathe” air in and out as the oil level rises and falls. The filters prevent the penetration of contamination from the ambient air in the hydraulic fluid.
BFD
The Eaton tank breather filters of the Series BFD prevent water and other contaminants from entering fluid reservoirs where differential pressures can occur through thermal expansion and contraction of the fluid, or during filling or emptying procedures.
