Hurricane filter housings offer more than double the performance of any comparable cartridge filter. NSF 61-listed Hurricane filters provide long filter runs, reduced maintenance, energy savings and lower filtration costs with the Combination Centrifugal Separator and Cartridge Filter. Dense particles are separated and discharged in the filters outer chamber, lighter particles are then removed in the inner chamber via High Surface Area cartridge(s) which can be cleaned and reused. The liquids rotational flow impacts the cartridge’s deep angled pleats creating pleat flutter for exceptional particulate loading. The Up-Flow technology automatically purges air from the vessel ensuring that 100% of the media is used 100% of the time.
