Abstract

The air filter systems described herein include one or more pulse collectors and pulse generators aligned along pulse axes. The pulse generators and filter elements may be arranged along a pulse distance as measured from a pulse outlet to a filter element opening. The pulse collectors and the filter elements may have openings with a relationship between them within parameters described herein. The pulse collectors may have a relationship between their hydraulic diameter and their length within parameters described herein. The pulse collectors may include a filter section and a pulse section that meet at a junction along a length of the pulse collector. The pulse sections may have a hydraulic diameter that increases when moving from the junction to the tube sheet opening of the pulse section. The filter sections may have a hydraulic diameter that remains constant when moving from the junction to the filter end opening of the filter section. Filter elements/cartridges used in the air filter systems may have filter media shaped or formed into ovate cross-sections
