Filter cartridges need to be changed before they become plugged.
Many operating plants schedule a change out of their dust collector filters on an annual basis. Some sites, with difficult to handle materials schedule these changes twice per year.
How often you need to change your filter cartridges will depend on the number of product deliveries that your plant receives. A site that receives six deliveries per day will have to change out their dust collector filters more often than a site that receives one delivery every two weeks.
These filters should also be changed out when the normal built in cleaning cycle, whether reverse pulse jet or shaker, does not adequately clean these filters.
Operating Tip: check to be sure that your compressed air source is clean, dry air - and that the minimum recommended operating pressure is maintained during the entire silo fill cycle.
