Donaldson, a leader in filtration technology, has released a new dust collector range with innovative PowerCore® technology. The PowerCore VH series for abrasive dust applications complements the existing PowerCore CP series, which is especially well suited to fluffy and fibrous dust applications. The PowerCore dust collectors handle high airflow, heavy dust loading and challenging particulates and can be fitted into the smallest places. The filter changeout is easy, quick and astonishingly clean compared to traditional filter bags and cartridges. This enables easy and safe maintenance.
In comparison to conventional dust collectors, units that use PowerCore® technology are up to 70% smaller. The core of the technology are the new PowerCore filter packs. The filter packs take proprietary Ultra-Web® nanofibre filter media and form it into flutes that collect particles without depth-loading (See Figure 1). The new Donaldson dust collection technology allows the handling of more air through the same amount of media than conventional filter bags or cartridges and therewith enables extreme downsizing.
The filter packs are light-weight and can easily be handled by one person. While previously replacing a traditional bag filter or cartridge took 10 minutes, the time for replacing a PowerCore® filter pack is reduced to only two minutes (See Figure 3). At the same time the filtration efficiency is considerably increased. Independent lab tests confirm: PowerCore® filter packs provide 78% fewer emissions than standard polyester bags.
All PowerCore® dust collectors include an innovative cleaning mechanism with pulse shaping technology to achieve the strongest cleaning energy and an effective dislodging of the dust from the fluted shape filter packs. The resulting pulse flow effectively covers the entire media pack, improving filter efficiency, keeping pressure drop low and increasing operational life. The dust collectors are available in two ranges, suiting the specific industry requirements, one of which is relevant to cement.
PowerCore CP: The PowerCore CP series is for fibrous and fluffy dust as well as venting and bulk handling applications. The stand-alone CPC dust collectors, which can be ducted to many different installations, have been redesigned to further enhance the ease of maintenance. The CPV (bin vent unit) can be used on silos, conveyor transfer points, conveyor discharges, blenders and mixers. The range is available for volume flows of 1200-27,000m3/hr.
