Improving performance of dust collection equipment with spun-bonded, pleated filter elements

This paper will present a case study of an aggressively designed pulse-jet dust collector, which, although adequate for past operating conditions, is now encountering multiple problems. These problems include high air-to-cloth ratio, emissions, inlet abrasion and loss of production. Using pleated filter elements dramatically lower-ed the differential air pressure in this foundry application, in addition to decreasing maintenance requirements and improving filter efficiencies.
