New Donaldson dust collectors: Performance follows shape
The new cartridge dust collector system, the Downflo Evolution (DFE) dust collectors, was displayed at the Powtech 2016 for the first time. While cartridges are round, the development engineers at Donaldson have chosen a new shape. The advantage of this innovation: The pulse cleaning has more filter area on the bottom of the cartridge. The dust can thus freely fall into the hopper. Users therefore benefit from improved cleaning and a lower pressure difference.
Also, the new design of the filter cartridges leads to significantly more compact dimensions of dust collectors and ultimately to an outstanding power density. Depending on the application, it can reduce the number of cartridges compared to usual cartridge filter systems by up to 30 %.
The DFE dust collectors also reach a high performance, because the Ultra-Web filter technology with its nano finest fibres already holds back particles in the sub-micron range. The resulting filter cake can be removed by the automatic, compressed air-saving MaxPulse pulse cleaning system with high efficiency. In addition, the optimized flow of dusty air contributes to the extremely high power density through the filter housing. Easy maintenance is also convincing: the asymmetrical suspension yoke of the cartridge filters can be opened and closed without tools.
The practice-oriented development of the Downflo Evolution dust collectors can be used in a wide spectrum from the pharmaceutical and food industry and the metal, cement and glass processing treatment to plasma cutting technology for volume flow rates from 2500 m3/h up to 150 000 m3/h.
