Is there any room for substantial improvement in the industrial safety and relevant environmental technology in dust removal? Connoisseurs on the subject will be sceptical about this question, as they are aware of the fact that there has been no leap in the development for many years, if not even decades.
Together with the chemical fibre industry, one of the worlds leading filter manufacturers, Donaldson Inc., now succeeded in developing a filter media which exhibits a service life which is two to three-times longer compared to that of conventional filter media. This has been made possible by the employment of a new production procedure: the hydroentanglement process permits processing fine polyester fibres to a stable fleece with very small pore sizes and high efficiency for dust filtration.
Compared to the filter fleeces used so far, many more dirt particles can be catapulted onto the smooth surface of the new Dura-Life™ filter media. Therefore the cleaning of the medium is much easier, with lower pressure and smaller mechanical load. Clearly less particles are set off in the depth of the medium, where the removal is only limited and leads to an increase in the differential pressure. The advantage for the user: despite longer service life and higher filter efficiency the differential pressure remains stable. The service life extension does therefore not have to mean higher energy expenditure.
Dura-Life™ extends the service life of the bag and baghouse filters not only by some little percentage, but by two to three times the life-time. Thus also the costs for filter elements are at least halved – the user or service provider has to exchange the filter elements, which is often under strict requirements for industrial safety, only halve so often. Users that do not have Donaldson filter units can also benefit from these advantages, because Donaldson also offers the new innovative Dura-Life™ filter medium for competitor housings.
Users who plan the acquisition of a new dust collector installation e.g. the DALAMATIC™ series, when using Dura-Life™: they can select a smaller unit with the same efficiency as the user benefits from the more favourable “air-to-media” ratio.
With Dura-Life™ Donaldson has once again developed and brought an innovation in industrial filtration to the serial production stage, which offers users genuine cost advantages.
If you are interested in knowing exactly which financial advantages a change to Dura-Life™ technology offers, you can find some calculated examples on the internet site www.duralifebags.com. Furthermore the user can even calculate the cost advantages in Euro and cent, because Donaldson has developed a software tool which determines the considerable saving potentials on the basis of the individual operating parameters. Europe-wide the Donaldson service can be requested to conduct a direct and practise related free-of-charge check on your existing dust collection installation.
