New filter medium
It is reported that differential pressure in filtering compressed air and gases is now being reduced by 50%, thanks to a new filter medium. Developed by engineers at Donaldson in Germany UltraPleat filtration technology uses a new structure of coated high-tech fibres that are processed into a pleated filter medium with a high separation efficiency of liquid particles and a huge adsorption capacity for solid particles.
The multilayer structure of the new filter medium was designed so that optimal aerodynamic conditions are achieved, simultaneously providing a filter surface that is over 400% larger by comparison with wound filter media.
For the separation of oil aerosols, an efficiency of ≥99.9% in accordance with ISO12500-1 is achieved. The filter performance data in compliance with ISO12500-1 and ISO12500-3 have also been validated by an independent institute for energy and environmental research.
