Air Filtration

The Importance of Air Filtration

Today, engines are designed and manufactured to generate more power with low fuel consumption and to be noiseless and long-lasting if it is protected, at low emission values.

Engines need high amounts of dry and clean air to produce efficient power for long life.

The engine needs good air filtration due to dust, soot, pollen, water particles and etc. in the air. If quality air filtration is not provided, fuel consumption increases by 30%. 1 gr dust per HP is sufficient for engine parts to wear out and malfunction.

Air Filter Quality and Filtration Properties

Quality Air Filter should be manufactured in technological production processes by using high technology raw materials and materials and tested and approved in advanced laboratories, compact, with optimum filtration area, high efficient, with low pressure difference in air passage, high dust retaining capacity, able to withstand varying temperature and humidity conditions, easy to be disposed and/or recycled.

However, the filters produced under these conditions can be described as good quality.

Filtration Properties


Efficiency refers to the ratio of the amount of retained particles to the total amount of particles. The high efficiency filter is the filter that can retain low-micron particles at the desired life. The efficiency ratio of the air filter in the new generation engines is expected to be 99.50% and above.

Pressure Difference

Pressure difference can also be referred to as resistance against to flow. If the air filter starts to show a high resistance against to flow at the earliest or an early resistance (early clogging) when using, it will block the amount of air that is tried to be sucked by the engine. The filtration material, which must be of high quality, should have a high dust retaining capacity without producing a high pressure difference in both the high efficiency and the expected life.

Resistance to Moisture and Heat Change

Depending on the ambient conditions, the filters are exposed to water, moisture, variable temperature conditions (e.g.: rainy weather, engine and ambient temperatures, etc.). The materials used in the filter must be durable against these conditions and should not lose their function.

Filter Life

Shelf Life : It has a minimum shelf life of 5 years in its package without humidity, at -10 +40 C temperature range, without exposure to water and direct sunlight.

Life Cycle : During air filtration, the filter holds contaminants in the air that is absorbed. This leads to clogging of the filter in time. Therefore, the maintenance and replacement period that the vehicle manufacturers have reported for the replacement of the filters must be observed. If the end-of-life, clogged filter is not replaced, the engine will not be able to draw enough air.

The air filtration system and the filtering element are designed according to the fitting engine, the mounting part, the operation period of the vehicle, the maintenance period and other conditions.

Different designs are applied for cars, light commercial vehicles, public transport vehicles, heavy commercial vehicles; vehicles operating in very dusty environments such as the agricultural sector, excavation and construction sites; and air, sea and rail road vehicles.

Long-term operation in extreme dusty conditions, prolonged exposure to sooty exhaust fumes, and water absorption to the filter lead to early clogging of the filter, in other words, early termination of the life cycle.

  • Poor Quality Air Filtration and Negative Results
  • Only price-oriented poor quality material
  • Design based on insufficient knowledge
  • Poor manufacturing conditions
  • Releasing products to the market without testing due to lack of laboratory
  • Instant cheapness can bring constant expensiveness !
  • Excessive fuel consumption
  • Power loss to the engine
  • Oil consumption and increasing power loss due to rapid wear-off of engine parts
  • Increase of overheating
  • Increase of engine noise
  • Increase of exhaust emission values
