Following are our stock filters:

The air filters designed and produced by SL Filter are mainly applied for passenger cars, heavy duty vehicles, construction machinery, and agriculture machinery. These filters provide the engines with clean air to operate with optimal efficiency and extend their working lifetimes.
If the air adsorbed by engines does not meet the filtration precision requirements, for example, there will be dust impurities and alumina in the air. This will cause premature wear on the cylinder barrel and piston ring, negatively affecting engine performance and service life.

Our oil filters purify the engine oil by filtering out metal debris, carbonized particles, and other impurities. The oil filter ensures clean running to protect parts and extend the working life of the entire engine.
In order to ensure high impurity filtering efficiency, SL Filter adopts high performance composite filter paper, which can protect the engine more effectively. The seals of our oil filter has very good sealing performance and can effectively protect the engine even at long-time high temperature or low temperature environment. Our oil filter bypass valves meet the strict testing standards, which makes sure the engine keeps a stable oil supply when the filter element is blocked.

During the fuel storage or filling process, there are always some impurities and water will be mixed into the oil supply system or engine cylinder, and they will cause damage to the fuel-system components. Before the fuel enters the fuel pump, it is the fuel filter that helps to filter out the impurities and ensure the normal operation of the oil supply system.

SL Filter provides various gasoline filters for cars and diesel filters for construction machinery, and we have different solutions for different models of cars. For example, some of our diesel filters adopt filter paper as the filter element, but also some adopt wool felt or high polymer material as the filter element. These designs are made to meet different water filtering requirements.

With more than 20 years of experience in the development and production of high-quality filters, we fully understand the ins and outs of the operation of various types of equipment that are compatible with our products.
