Pressure Lubrication is the second type of lubrication systems. This system is more technically advanced and a far more precise method to deliver oil to critical parts of the pump, resulting in longer pump life. The oil is pumped through an oil filter and into the pump where it is then recycled and reused. Since the oil pump is delivering the oil more efficiently the viscosity of the oil is less critical than with a splash system. In the air compressor industry, it is typically more costly to upgrade to pressure lubrication systems. *Our high efficiency manufacturing facility 0to the tank.
