MANN+HUMMEL launches filter media testing at conference

MANN+HUMMEL recently introduced simulation techniques that can be applied to determine the performance of filter media. Replacing time-consuming “multi-pass testing,” they accurately represent the filtration processes in 3-D fiber structures. The company conducted a presentation at the recent World Filtration Conference in Leipzig, Germany.

Comparisons with measurements taken on actual filter media are also available. Initial results indicate that the simulations to a large extent correspond to the actual measurements for all three performance criteria, namely filtration efficiency, pressure loss and particle holding capacity.

MANN+HUMMEL, development partner and original equipment supplier to the international automotive and mechanical engineering industries, is now in a position to calculate the particle holding capacity of oil and fuel filter media.
With the development of new high-performance engines, filter media must constantly meet increasingly demanding requirements, states the company.

Now that the possible options for using paper in certain applications such as gearbox oil filters have been exhausted, the outlook for new synthetic fiber media is extremely promising, the company adds. Simulation programs help to design more quickly and economically the fiber structures of these new filter media which meet the customer’s specific requirements.
