Introduction to Pulse-Jet Filter Bags
How Pulse-Jet Filter Bags Collect Dust
Pulse-jet filter bags are used to remove dust particulate and contaminants from the air in warehouses, plants, factories, foundries, and more. Pulse-jet is one of the most common styles of baghouses you will see across a variety of industries and applications. With this style of baghouse, dust collects on the outside of the filter as clean air exits through the inside of the bag.
How Pulse-Jet Filter Bags are Cleaned
To clean pulse-jet baghouse filters, a blast of compressed air is injected through a blowpipe over each row of bags via a venturi. In a pulse-jet baghouse one row of bags can be cleaned while the remaining rows continue to collect dust particulate. This is known as on-line cleaning.
Construction of Pulse-Jet Filter Bags
Pulse-Jet baghouses are engineered to hold either bottom or top load filter bags and cages. Fabric filter bags used in pulse-jet and plenum pulse baghouses come in a variety of medias and treatments. The type of filter media and treatment that’s best will be dependent on a plant’s application and dust characteristics. To get a free filter recommendation, check out our filter bag media quiz here.
