Several technical factors determine which bag is suitable: Temperature: Record the normal operating temperature as well as startup, shutdown and upset-condition peaks. Dust type: Determine whether the dust is fine, coarse, abrasive, sticky, oily, hygroscopic or electrically conductive. Chemical exposure: Identify acids, alkalis, solvents, oxidising agents, moisture and other substances in the process stream. Particle size: Particle distribution affects the choice of media and surface treatment. Bag dimensions: Confirm the length, diameter, top and bottom configuration, sealing method and cage dimensions. Cleaning method: Establish whether the system uses pulse-jet, reverse-air or mechanical-shaker cleaning. Sharing this information helps the filter bag manufacturer in India develop a solution around the actual process rather than simply reproducing the old filter.
