Replacement pleated paper filter cartridge for dust collectors. Cartridges available for mobile, blastroom and cabinet dust collectors. Tried and proven in the Abrasive Blasting Industry. Choose from standard or Ultra-filtration alternatives. Ultra-filtration cartridges have a nylon web sprayed on the paper filter prior to pleating. This allows air to flow through and strengthens the filter paper. Minimizing unnecessary pulsing extends cartridge life. This unit is capped on one end. Talk to your BlastOne area manger for assistance with setting dust collector reverse pulse. Multiple sizes and configurations available.
