Gold Cone™ X-Flo (GCX) filter cartridges are the most advanced dust collector filters ever made. They feature proprietary HemiPleat® Gold Cone™ filters that stay cleaner and last longer than conventional pleated filters. Each GCX filter contains 375 square feet of media, offering the industry’s highest air-to-cloth ratio. The innovative design provides a low pressure drop, which means fewer filters are required for a given application. GCX filters were designed specifically for the Gold Series X-Flo dust collector. Used together, you get the most powerful and cost-efficient dust collection system on the market. The system maximizes airflow while minimizing filter change-outs, compressed air usage and energy costs.
