New Dust Collector Design Shapes Improved Performance
“Form follows function.” Until a few years ago, this design maxim was still of secondary importance in filtration technology. Bag filters and cartridge filters in a round shape were the standard in dust filtration.
The housing and cleaning methods matched this traditional shape of filters. In recent years, however, there has been a clear trend towards application-oriented solutions which are based on innovative shaping.
The Downflo® oval dust collector with its oval cartridges was a crucial step in the improvement of filtration performance. This was followed by the PowerCore® technology, which set entirely new standards, both in shaping and in housing design, and allowed for a significantly more compact system design.
These dust collectors are up to 70 % more compact than conventional dust collectors. Changing the filter pack also takes only one fifth of the time in a direct comparison.
Increased cleaning performance with lower differential pressure, easy handling and maintenance.
These objectives are achieved with the latest development, the DOWNFLO® EVOLUTION (DFE) dust collector. The Donaldson engineers have developed a filter cartridge with the shape of a rounded triangle.
These “triagonal“ cartridge filters with Ultra-Web® filter media guarantee perfect airflow conditions and the filter cakes can be removed effectively using the automatic, compressed air-saving “MaxPulse” pulse cleaning system.
In addition, the new design of the filter cartridges results in significantly more compact dimensions for the dust collector and thus in an outstanding output density.
Depending on the application, the number of cartridges can be reduced by up to 40 % in comparison with conventional cartridge filter systems. The ease of maintenance is just as convincing. The quick release fasteners on the “triagonal” cartridge filters can be opened and closed at a touch without any tools.
The DOWNFLO® EVOLUTION dust collector was developed in accordance with practical needs and permits use in a wide spectrum of applications, from the pharmaceutical and food industries through metal and glass processing to laser cutting technology for volumetric flows from 2,500 to 150,000 m3/h.
The use of innovative materials and technologies and the implementation of a flow-optimised shape results in sustainable, economical solutions for a wide range of dedusting tasks and allow tailormade customer solutions of the system‘s technology.
The prerequisite for this is a comprehensive range of innovative filter media and filter elements – supported by a high-performance after sales service.
