Hydraulic Oil Purification Unit (model #04-410-05) Principles of Operation

Contaminated hydraulic fluid is drawn from the aircraft or drums into the oil purification unit by a pump. The oil passes through the inline first stage 1 micron filter. Then through a low watt density heater where the oil is heated to an optimum temperature of 150F.

The oil then enters the distillation column where it is exposed to the vacuum through the use of special dispersal elements. This increases the exposed surface area of the oil and converts the trapped water in the oil to vapor form. It is then drawn through the heat exchanger by the vacuum pump in which the water vapor is cooled and water droplets are formed. The water droplets collect in the condensation for removal.

The water-free oil falls to the bottom of the column and is removed by a heavy duty pump. This pump forces the dry oil through a second stage .25 micron particle removal filter. Clean, dry oil passes out of the unit back to the aircraft's system and or drum.
