Product Description

Small oil filter press machine oil pressing filtering machine

LY Series Plate Frame Pressure Oil Purifier is specially designed for purifying various industry oil,
effectively remove water and mechanical impurities from oil, improve oil quality and ensure safety operation of industrial equipment.

This machine can be widely used in the industries such as power station, electricity factory,power electrical substation of industrial and mineral enterprise, lube oil depot, tractor station, petroleum, chemical engineering, metallurgy, national defense unit, etc, filtering water and impurities of transformer oil, turbine oil, engine oil, EP gear oil, machine oil, diesel oil, kerosene, hydraulic oil, aviation hydraulic oil, as well as edible oil while using stainless steel plates and frame. It is also a great choice for pre-treatment, prior to high vacuum oil purifier machine.

This machine consists of filtering bed, oil pump and primary filter. This machine use filter paper, filter fuse or filter cloth as filtration media, which are installed and fixed between the filter plate and filter frame. 
The filter paper, filter fuse or filter cloth plays a very important role of filtering.

When you operate the battening device, there will form a single independent filtering room under the pressure of the packing device, then the water content and impurities are removed by filter media.


1. Simple structure, plate pressure type filtering method, filter paper,filter fuse or filter cloth as filter media.
2. No heating, the additives in the oil are well prevented from degradation or deterioration.
3. Easy to operate, with simple structure, small volume, light weight, easy to carry and operate.
3. Low operation cost, low maintenance time and cost
4. Special boosting type oil pump has strong suction ability and make the machine to be used in more oil types.
5. Low noise, quick and convenient to replace the filter paper.
6. High efficiency, can effectively purify the tiny and fine mechanical impurity from oil.


It takes the filter paper as the filter element, the waste oil is injected into the machine under high oil pressure, which produced by the oil pump. The impurity is hold up by the superimposed filter paper. 
When the value of oil pressure excess to a setting value or the filter paper is wet, we just need to change the new filter paper, then it can work normally. 

Filtering paper (The filtration accuracy can be customized)
