The role of the air filter<\/h2>
An essential part of the engine, the air filter removes dust and other impurities from the air before they reach the vehicle’s intake system.<\/strong> In other words, it maintains good air quality, which is essential for fuel combustion. By blocking these contaminants, it also protects the rings, pistons, liners and turbo from premature wear and extends the life of your engine. <\/div>\r\n<\/div>\r\n\r\n\n\n
\r\n
\r\n
\ud83d\udca1 The more powerful an engine is, the more air it requires. For example, in one year, a truck will absorb 2,600,000 m3 of air! As the amount of air consumed increases, so does the risk of contamination and the air filter is vital to the engine.<\/strong> With this product, you maintain the performance of the engine system and protect its parts. That is why at HIFI FILTER\u00ae we pay particular attention to the manufacture of our air filters.<\/div>\r\n <\/div>\r\n

What are the different types of air filters?<\/h2>

The dry air filter<\/h2>

Dry air filters are the most commonly used.<\/strong> They are installed in a housing and come in the form of a cartridge or a panel. Depending on the model of your vehicle, this box may contain an additional protection: if the main filter fails, a safety filter will temporarily retain the dust. This protects the engine parts until the air filter can be replaced quickly.<\/p>\r\n

How does an air filter work in practice?<\/strong> The operation is simple: the contaminated air passes through a pleated cellulose medium. This retains the particles and the purified air reaches the intake system. Each HIFI FILTER\u00ae model is adapted to your vehicle and offers an adapted filtration threshold.

\u201c<\/span>\u26a0\ufe0fDepending on the age of your vehicle, the housing of a cartridge filter will be different.<\/strong> Axial sealing cartridge housings are frequently installed on older vehicles. On newer vehicles, radial sealing air filter housings are mainly used.\u201c<\/span><\/div>\n

High efficiency air filter <\/h2>
This air filter combines two filter media in a single housing to ensure optimal filtration. The main cartridge, equipped with an expanded filtering surface, retains up to 99.97\u202f% of impurities while maintaining a high airflow<\/strong>. Additionally, the integrated post\u2011filter acts as a safety barrier: it captures remaining particles if the main cartridge becomes saturated or if it is damaged. This design provides long\u2011lasting protection for your engine and ensures optimal performance.<\/div>\r\n <\/div>\r\n

\r\n

The oil bath filter<\/h2>

This type of air filter is mainly installed on older vehicles.<\/strong> Here are the details of how it works: the air, loaded with particles, passes through a central tube to reach an oil pan. Thanks to the viscosity of the oil, the impurities are captured. The air flow continues to a filter mass (made of metal, PPI foam or cocolatex), which is responsible for retaining the oily residues.<\/p>\r\n

With an efficiency of 95%, an oil bath filter is not suitable for modern machines<\/strong>. Why not? The increased performance of these machines is accompanied by an increase in their sensitivity to contaminants. It is therefore essential to install a filter with a higher efficiency.<\/p><\/div>\r\n <\/div>\r\n

When should I replace my air filter?<\/h2>

An air filter can only guarantee optimal protection for your vehicle if the maintenance interval is respected.<\/strong><\/div>\n <\/div>\n<\/div>\n\n
\r\n
When replacing an air filter, rely on the manufacturer’s recommendations or on the clogging indicator (mechanical or electrical) if there is one<\/strong>. According to the manufacturers’ recommendations, change your filter every year. On a mechanical indicator, if its piston turns red, replace your filter. If the indicator is electrical, change your filter when an orange light appears on your dashboard indicating a problem with the air filter.\r\n\r\nFor oil-bath filters, the oil should be changed, cleaned and replenished ideally every 50 hours. <\/div>\r\n<\/div>\r\n\r\n\n\n

In a very dusty environment, your air filters will become saturated more quickly and need to be replaced more often.<\/strong> But how do you know when a filter is dirty? If the filter is clogged or worn out, the quantity and quality of the air delivered will be reduced<\/strong>. As a result, the engine will not be supplied with enough air and combustion will be impaired. If this happens, there are several symptoms that can alert you:\r\n
