1.  Fried concept

The oil filter in external or internal, invisible magnetic products, also can not detect magnetism, it is common to the existing oil filter added reclame, consumers need to be cautious when buying.

2. The existing ordinary oil filter shell is equipped with a magnetic shielding layer

The oil filter device is a magnet with magnetic shielding materials, using a fixed structure, or magnetic magnet is used to its adsorption in the existing filter housing, for ferromagnetic impurity adsorption in the oil filter. But in the actual use of the device, because most of the magnetic field is shielded by the oil filter shell, magnetic field utilization efficiency is very low, basically do not work. In addition, when the vehicle is running on the bumpy road, it is easy to cause the filter oil leakage or fall off, causing incalculable damage to the vehicle.

3. The existing ordinary oil filter shell surface directly adsorbed on one or several magnets

The magnet is directly adsorbed on the oil filter housing available on either side or paste in the oil filter, oil filter at the bottom, not only to the filtering effect, but also interfere with the normal operation of other electronic devices on vehicles, dangerous consequences.

4. The magnet is arranged on the casing of the bypass valve  

When the filter is working, the bypass valve is closed. The oil is fed back through the paper filter to the engine, and the main oil flow is less accessible to the bypass valve. The magnet arranged on the bypass valve housing, not only filter effects on the ferromagnetic impurities is small, but also lead to bypass valve failure, the circulating oil through the bypass valve directly back to the engine, resulting in non ferromagnetic impurities are not effectively filter paper filter, or the bypass valve plug, choke burst paper filter.

5. Strong magnetic oil filter
A strong magnetic filter element is arranged in the center pipe of the filter near the oil outlet end. The use of the filter itself and the central tube instead of the magnetic shielding layer, the filter shell outside the strong magnetic field to achieve double shielding, to avoid the strong magnetic field of the strong magnetic field leakage interference of other equipment.
