Oil Filters

El filtro de aceite está diseñado para eliminar los contaminantes del aceite. El filtro protege de forma fiable el motor del coche gracias a los materiales filtrantes avanzados de última generación especialmente desarrollados. Estos materiales tienen alta capacidad de absorción y eficiencia de filtración, capturando incluso las partículas más pequeñas que surgen durante la operación. Esto reduce el consumo de combustible, libera todo el potencial del motor, garantiza su limpieza y prolonga su vida útil.

TOTACHI OIL FILTER DESIGN

LET'S TAKE A CLOSER LOOK AT ALL THE KEY PARTS OF OIL FILTERS

FILTER ENCLOSURE

High quality of painting and text printed on TOTACHI filter enclosure: paint and text won’t be erased under mechanical influence or exposure to oil-containing and chemically active liquids.

All TOTACHI oil filters have the date of manufacture printed thereon; this allows to control the quality of products of each batch and shift in details.

The filter enclosure wall is sufficiently thick and strong to prevent its destruction in case of excess pressure.

The inner surface of the enclosure has a durable corrosion-resistant coating, preventing rust formation due to condensation.

FILTER BOTTOM

Automation of metalworking and assembly processes ensures 100% product quality.

On TOTACHI filters you will never find metal burrs, poor-quality drain holes, or chip residues

High precision thread cutting
Drain holes and burr-free threads
The bottom of the filter has a durable corrosion-resistant coating

ANTI-DRAINAGE VALVE

TOTACHI oil filter anti-drain valve:

Tight fit to the bottom of the oil filter and reliable sealing
Remains elastic under any temperature conditions
Remains elastic throughout the entire service life

FILTER CELL

The filter cell is the most important part of the entire oil filter!

TOTACHI makes the filter cell as high as possible, which increases the width of the filter screen (material).

TOTACHI makes the maximum number of material pleats in the filter cell, thus increasing the area of the filter screen.

TOTACHI makes the folds of the cell evenly spaced, ensuring uniform oil throughflow and low resistance of the filter cell.

The ability to retain impurities (dirt capability) and filter life depend on both the quality and the area of the material

Filtering efficiency (filter rating, filter adequacy, and flow resistance) depends on the filter material.

TOTACHI employs only high-quality filtering materils able to meet the toughest requirements of car OEM-manufacturers in all respects.

Filtering material is one of the most expensive filter components. Many manufacturers use cheap materials in pursuit of price.

HEAT TREATMENT OF THE FILTER CELL

Heat treatment of the filtering material prevents further moisture absorption and swelling of the material in oil.
We corrugate the material in the longitudinal direction, which makes each pleat wavy and prevents adjacent pleats from sticking together during operation.
We make the internal stiffener, the upper and lower covers of the cell of high-quality metal with a corrosion-resistant coating.
We provide original assembly quality of cells.

This is the only manufacturing process that can provide filtration at the level of OEM-manufacturers' requirements and a filter life that will for sure last until the next maintenance.

BYPASS VALVE

During normal operation of the filter, the valve is always closed.

Its purpose is to protect the engine against oil starvation and excess pressure inside the filter.

In case of excess pressure, the valve opens and allows free circulation of oil bypassing the filter cell (this usually happens during a cold start in frosty weather and in case of high oil viscosity).

The opening pressure of the bypass valve is strictly regulated by the vehicle manufacturer.

TOTACHI VALVE RELIABLE OPERATION GUIDE:

We strictly follow specifications of car manufacturers.
We use reliable designs that can provide the required valve capacity for each modification.
For the best assembly tightness, we use different high-quality materials depending on the valve design: metal with corrosion-resistant coating, metal with rubber coating, and special polymers.
We provide original assebly quality.

ENCLOSURELESS FILTERS – CARTRIDGES

In addition to conventional non-serviceable filters, there are even more high-tech filtering systems in the form of a replaceable cartridge.

They are easy to distinguish since they do not have a metal enclosure. Such a filter is installed directly into the enclosure, which is an integral part of the car engine.

The main enemy of any filter is pressure drop. When a filter becomes clogged, the upstream pressure of the filter material becomes much higher than the downstream one. This is called pressure drop. If the drop is high enough, the filter material may collapse.

This is where the bypass valve comes into play. The bypass valve allows oil to bypass the filter if it is clogged. This prevents the collapse of the filter, but the oil itself is no longer filtered.

A check valve or anti-drain valve prevents oil from draining or pumping back into the oil pan. In some cases, a check valve prevents the oil level in valve train components from dropping when the engine is turned off. This can help to prevent dry starts and bearing damage.

The main advantage of a filter cartridge is that the manufacturer’s valve system remains unchanged, and the cartridge itself is noticeably cheaper. Cartridge filters are also more environmentally friendly due to their ease of recycling and/or disposal as compared to filters with enclosures.

In most cases, a cartridge filter is installed in a vertical position. In this case, the filter can usually be opened and inspected without the need to drain the engine oil. This gives you an easy way to check for impurities, debris or other problems with your engine oil.

In terms of performance, both cartridge filters and oil filters with enclosures provide equally high filtration efficiency.

But cartridges have a drawback, since such filters are more difficult to replace, as in addition to the filter itself, the O-rings are also replaced. And the installation location is often in a hard-to-reach place.

ADVANTAGES OF TOTACHI FILTERS

TOTACHI FILTERS HAVE
THE FOLLOWING PROS:

High filter rating;
High filter adequacy;
Low flow resistance;
Increased dirt capability;
Long service life, exceeding the requirements of OEM equipment manufacturers to service intervals

When is it necessary to replace the oil filter?

The oil filter needs to be replaced during each oil replacement. The replacement interval is indicated by the manufacturer in the vehicle’s service book. Typically, a service interval for a passenger car is 10-15 thousand kilometers.
