How does filtration work in off-highway vehicles in Cambodia? We have drawn on what was reported and compiled by AB Newswire.

Filtration in Cambodia

Filtration in Cambodia. Since the emergence of Coronavirus

According to them, “since the emergence of coronavirus (COVID19), import and export transportation has been greatly affected. Excavator parts, as a kind of item that is frequently replaced, especially maintenance parts like filters (oil filter, fuel filter, air filter and etc.), their demand and the use has rapidly increased around Phnom Penh, Cambodia local market. As people know, hydraulic systems or engine systems are often equipped with filters. As impurities build up on (or in) the filtration medium of a filter, it will affect the filtering effect. This requires periodic replacement of the filter element (or the entire filter, if the element is not separately replaceable).


Hence, an increase in the number of excavator parts manufacturers like filter manufacturers, making it difficult for both local and international buyers to know the best quality manufacturer for supplies. However, this article guide is meant to help you make the right choice through comprehensive research that exclusively came up with the list of Top Filters Manufacturers. If you need to purchase filters from Phnom Penh, Cambodia, like filters of CAT, Komatsu, Kobelco excavators. But still need to ascertain which the right manufacturer with the best reliable and efficient quality filters is to buy from, this guide listed the best Cambodia-based filters suppliers. Every manufacturer on the list below is capable of fulfilling international product supplies of safety, quality, and efficient filters, including oil filters or fuel filters, or air filters.


The filter refers to an accessory that filters impurities or gases through filter paper. Generally refers to the excavator vehicle filter, which is an engine accessory.

Engine filters and excavator oil filters

According to different filtering functions, it is divided into oil filter, fuel filter (gasoline filter, diesel filter, oil-water separator, hydraulic filter), air filter and etc. The engine filters are air, oil, and fuel filters. The oil filter is located in the engine lubrication system. Its upstream is the oil pump, and downstream is the parts that need to be lubricated in the engine. Its function is to filter out harmful impurities in the oil from the oil pan, and supply the crankshaft, connecting rod, camshaft, supercharger, piston ring, and other motion pairs with clean oil to play the role of lubrication, cooling, and cleaning, thereby extend the life of these parts.


It’s designed to remove contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil. Other vehicle hydraulic systems, such as those in automatic transmissions and power steering, are often equipped with an oil filter.  Oil filters are used in many different types of hydraulic machinery. In Cambodia, CAT excavator is the most commonly used, such as CAT320D, CAT312. So the oil filter of CAT machine has good sales.

But when you choose oil filters, please remember ‘next level’ product will occur the following problems:

• Filter out 60% of impurities in the oil, with low filtration efficiency;

• Under special conditions, the filtration efficiency is zero.

• Besides, the quality of filter paper is also important.

Oil filters have higher requirements for filter paper than air filters, mainly because the temperature of the oil varies from 0 to 300 degrees. Under severe temperature changes, the concentration of oil will also change accordingly, which will affect the filter flow of oil. The filter paper of a high-quality oil filter can filter impurities and ensure sufficient flow under severe temperature changes.”
