Oil and fuel filter
We offer a wide range of oil and fuel filter to our cooperating distributor around the world. Our filter is more than even a component that has to combine economy and environmental friendliness with high functionality and efficiency. Protection of the engine, easy servicing, a high level of reliability and environmental protection are the key concepts here.
Long service intervals combined with new fully synthetic oils place even more stringent requirements on the oil filter elements. This stretches from the wide temperature range and aggressive oil components to oil aging components.
What the oil filter does
Friction is created when machine parts move in relation to each other. In order to reduce this friction, which causes reduction of efficiency and life of the3 machine, we need to create a lubricating oil-film between the moving parts. It is evident that we need lubricating oil,clean of dirt and damaging particles, in the machine, This is where the oil filter comes in.
Cooling:Absorb and transport heat from friction and engine heat.
Cleaning: Transport (to the filter) the contaminating particles from wear and tear as well as remainders of the combustion process.
Sealing: The rings between liner and piston, simmering etc.
Silencing: Silencing of mechanical noises and the combustion process.

Air filter
We offer a wide range of air filter and cleaner for various application
What the air filter does
Like all vehicle filter, air filter can be easily overlooked and are not replaced until they are completely full with contaminants. To ensure the engine is protected at all times and to prevent premature wear, it is important to maintain regular service intervals.
The air filter removes airborne contaminants such as soot, carbon and abrasives from the air as it passes through the filter.
“ASPIRE” and “DOPU” engine air filter use high-quality filter element to trap the airborne dust and dirt, including particles as small as a grain of sand and provide longer lasting engine protection.
