Purifiner oil filters are simple, but incredibly effective

The design is simple but highly efficient, where two techniques are used in combination to provide pure oil.
Purifiner has a 100 % cotton filter that removes particles down to 1 mµ from the oil. Water in the oil (combined), is evaporated off in the filter's upper chamber. 

The oil passes through the cotton filter and passes through nozzles in a spreader where a heating evaporates the water content from the oil through an evaporation valve.

In order to achieve efficient evaporation in Purifier's top chamber, it is necessary that evaporation chamber is not pressurised.In other words,the oil must be able to flow back from the filter to the system with no backpressure from the plant. This has created a number of challenges,as the majority of hydraulic systems work under some pressure, and we had to overcome this in order to return the clean oil to the system.

Purifiner is designed for the Continuous maintenance of Oil, not for fast filtering.



Purifiner cleans only 600 litres per 24-hours in continuous operation. Depending on the initial oil analysis, we estimate that the oil in the system must pass through the Purifiner 6-8 times before being completely clean. Consumption of filter cartridges is minimal.Only 6-8% of the water content of the oil is absorbed by the cotton filter.After primary start up on installation of Purifiner, expect to use 2-3 filter cartridges to get the oil completely clean, but once this has been done normal usage is between 3-4 cartridges per year for a standard hydraulic plant.
