Read our primer articles on Desiccant Breathers and Oil Filter Carts.

Recently I have built a homemade electrostatic oil filteration machine having 2lpm pump , 20 litre tank , 7 kv dc transformer . Filteration result is NAS 13 , after filtering for 12days for 100 litre oil . I want NAS 7 grade . Whether transformer capacity to be changed ? What should be ideal current in milliampere for 7kv transformer ? ANYONE who know the supplier who can supply good quality transformer for above purpose ?

First off there is more too it than zapping oil. At OILKLEEN we use 15,000 Volts and a new filter should have almost zero milliamps.

Since your particles are not dropping NAS classes any faster, I would say the problem is in filter design and not the power supply. Gap distance, flow rate, collection media, and number of fields, and high voltage is the trick, but making them all work together is the secret!

You should look at the OILKLEEN system, I can't give you all the secrets! Good luck!

My machine is not drawing 18 milliampere current while the machine is operating . It is the 18 milliampere current the machine is set to trip . When filtering it is drawing hardly 2 milliampere . Pump flow , number of field , gap distance are ok , I think I have to check dieelectric media paper . COULD anybody tell about parameters for dielectric paper ?
