Neenah Filtration develops medium for engine air filters

1 min read

German filter media specialist, Neenah Filtration has developed a 100% cellulose-based GESSNER medium for engine air filters in passenger cars which has up to double the dust holding capacity at high face velocity.

Decreasing space under the hood and the increasing volumes of air needed by engines today mean that highly specialised filter media with high dust holding capacity (DHC) are required.

Decreasing space under the hood and the increasing volumes of air needed by engines today mean that highly specialised filter media with high dust holding capacity (DHC) are required. Neenah Filtration’s A006D medium consists of 100% cellulose and has a special paper media design, both of which give the filter medium an increased lifetime.

The company says it offers higher efficiency compared to media with similar air permeability by up to 99.84% based on its flatsheet testing according to ISO 5011. In addition, there is up to 100% increase in dust holding capacity at higher flow velocities with only a slightly higher thickness compared to standard media. The final touch is the company’s latest resin technology, and the medium is available with flame retardancy according to DIN53438.

The Neenah Filtration team will be showcasing its media at Filtech, taking place 8–10 March in Cologne, Germany and FiltXPO, taking place 29–31 March in Miami, Florida, USA.
