Reducing CO2 emissions

An effective solution: engine intake air filters made of high-performing nonwovens

One of our key goals at Freudenberg is to create, energy-efficient concepts for the automotive industry. Just one example of this commitment is Freudenberg Sealing Technologies development of LESS (Low Emission Sealing Solutions): a unique, comprehensive solution that reduces emissions in passenger cars and commercial vehicles through more effective seals. As part of the global Freudenberg Group, Freudenberg Filtration Technologies also helps to reduce CO2 emissions in the automotive industry with our range of fully synthetic micronAir engine intake air filters.

Using micronAir to boost energy-saving potential

Increased pressure drop in engine intake air filters leads to increased amounts of energy required to achieve the same level of performance. When air filter resistance is increased as a result of dust build-up, more fuel is required. This in turn increases CO2 emissions. In this respect, standard filters are intrinsically inefficient – unlike micronAir filters. Due to their progressively structured high-performance filter media, fully synthetic micronAir filters are characterized by both excellent filtration properties and energy values.

micronAir engine intake air filters achieve a large dust-holding capacity with significantly less pressure drop over their entire operational life. This means:

  • Pressure difference only increases slowly
  • Pressure losses are significantly reduced
  • Less fuel is needed for the same performance
  • CO2 emissions are minimized
