Camfill Farr has introduced a big round filter (BRF) that combines ease of operation and service with superior reliability and a three- year warranty. The new reverse air dust collector uses a simple but effective design that minimizes the number of moving parts, reducing wear. In addition, the dust collector's cleaning system is self- contained and requires no plant compressed air. According to the company, its BRF is ideal for high-volume collection of dry dusts generated during powder and bulk handling operations.
