The air filter filters various impurities in the air to ensure that clean air enters the engine, so as to make the fuel gas more sufficient and the air system smooth. High quality air filter is an important part to ensure the normal operation of the engine. Shanghai Frega Company provides various high-quality metal air filters, plastic air filters, square air filters, air filter cartridges and accessories, which are widely used in various commercial vehicles, passenger vehicles, engineering machinery, mining machinery, generator sets and other fields. Shanghai Frega adopts high-quality raw materials, exquisite technology and elaborate design to meet the strict requirements of various customers for air filters. It can also be developed and designed according to customer requirements.

Metal air filter is an air filter product with a main frame structure constructed of metal materials, which not only ensures excellent filtration performance, but also has good mechanical strength and weather resistance. The metal air filter products produced by Shanghai Frega can work normally under the conditions of low or high temperature outside, especially suitable for the complex situation of Chinese roads

Shanghai Frega's new Optiair Lite series plastic air filter provides a complete solution for the engine intake filtration field. According to different application fields, the product flow of this series covers 93m ³/ h-2500m ³/ h。 The shell is made of special modified resin material, which has the functions of high light, high toughness, anti-aging, anti ultraviolet, etc

Combined air filter is to combine different filtration characteristics. Such air filter products have larger ash capacity and longer service life. Due to different combination forms, some have the characteristics of coarse filtration, and some have the characteristics of adapting to installation conditions. At present, Shanghai Frega has combined air filters with prefilters, combined air filters with raincoats, combined air filters with air intake systems and other products

The air pre filter is widely used in sites, mines, deserts and other places with high dust concentration. The installation of air pre filter in the air intake system can greatly reduce the dust and impurities entering the air filter, greatly extend the service life of the air filter, provide strong protection for the engine, improve the engine performance, and reduce the maintenance cost. The air pre filter of Shanghai Frega adopts American patented technology, which has the advantages of low flow resistance and high efficiency. We can also provide air pre filters of various flow rates and forms according to customer needs

The intake system is mainly composed of air filter, air flow meter, intake pressure sensor, prefilter, resonator, intake pipe, connecting pipe and other components. Its main function is to ensure that enough clean air enters the engine, ensure that the engine is fully burned, and improve fuel economy. At the same time, it can reduce the noise of the air intake system and improve the comfort of drivers and passengers. The CAE analysis method is adopted in Shanghai Frega, which is fully verified at the early stage of design to ensure the structural rationality and performance excellence of the intake system. In the later stage, strict experimental verification was adopted to ensure the reliability of the intake system. At present, we have developed various intake system assemblies for many well-known OEMs. At present, the company can provide services such as conceptual design, sample production and mass production of air intake system for various models. Applicable models include passenger cars, commercial vehicles, buses, engineering machinery vehicles, etc.
