It is well known，The function of the fuel filter in the equipment is to stop the particles in the fuel.、Water，And unclean substances，Protect the precision components of the fuel system from wear and other damage。The majority of users inevitably come into contact with filter products when using Dynapac road equipment.，But people are concerned about its material.、Internal structure、The advantages of the original filter element and the harm of the subsidiary filter element are not the same.，Today we will compare them through intuitive photos.，In-depth understanding of the original factory with you/Advantages and disadvantages of auxiliary factory filter。
The first is the difference brought by the material difference.。It can be seen from the following enlarged sectional view of the filter paper：
1. Dynapac Original Fully Synthetic Nano Filter Paper：
Fully synthetic nano filter paper is specially developed to meet the filtration effect required by Dynapac's real working conditions.，Better filtering effect；Design of Nano-layered Progressive Multi-layer Structure，Maintain high efficiency in the whole life cycle，Achieve long life and better protection of the fuel system。
2. Other filter paper：
From left to right：
Practical non-nano fully synthetic filter paper of other joint venture brands；
Low-end filter paper containing tree fiber used by filter element of subsidiary factory in the market；
Filter paper containing glass fiber used by a domestic brand+Metal Mesh。
About“Design of Nano-layered Progressive Multi-layer Structure”This technical term，Let's take the following figure as an explanation.，Give you instant insight into its benefits：
What are the advantages of Dynapac's original nano-filter paper?？
It can improve particle filtration efficiency.，And good filtering efficiency is maintained in the whole service life.：
Uniformly distributed fiber gaps can capture and retain particles on the filter paper；
Fully synthetic nano filter paper is not harmed by water or other chemicals in diesel fuel，Keep high filtration efficiency in the whole life cycle.。
As can be seen in the figure above，Ordinary filter paper（Left）And nano filt paper（Right）Filtration effect within a certain period of time：
If the ordinary filter paper is not replaced after a period of use, there is a risk of damage to the fuel system.，Uch as the plunger of a fuel injector、Seizure of delivery valve, etc.；
The nano filter paper keeps excellent and long-term filtration performance in the whole service life.。
What other hazards will non-original filters bring to your car?？
We did a fuel injector killer test.，As shown in the figure below：
Because the accuracy is much lower than the original filter.，Excessive particulate matter entering the system，The filter using ordinary filter paper showed seat wear at 37 hours under the impact of high pressure particles.，The amount of oil returned is ten times of the original amount.，However, the valve seat of the Dynapac filter using nano-filter paper was not worn after 190 hours of use.，And that fuel return quantity of the fuel injector is not increase。
As wear and tear increase，The valve seat will not be tightly sealed.，The fuel injection quantity is not accurate，Reduce the atomization effect，Resulting in reduced engine power、Increased fuel consumption、Black smoke and so on.，Resulting in a significant increase in operating costs。
Long-term use of subsidiary filter，It can also cause the needle valve to stick、The fuel injector is dirty、Oil pump rust and so on.。Like this，Buying subsidiary filters seems to save money.，In fact, the loss outweighs the gain。
Filter selection for equipment operation、Huge impact on equipment service life。The majority of users must be cautious when choosing filters.——The original filter is necessary to maintain the excellent performance of the equipment.，It is also the greatest guarantee to avoid abnormal wear and tear of equipment or even shutdown.。
