Cartridge filters: Transforming the field of dust collection

Since their development and introduction more than 10 years ago, cartridge filters have made steady inroads in the dust collection field. At first, cartridge filters replaced fabric filters only in the simplest of applications. Today, with improved design and cleaning techniques, they are being used in higher moisture and higher temperature applications than initially conceived. This article discusses cartridge filter technology and provides application examples for the chemical, pharmaceutical, paint and pigment, and foundry industries.

Cartridge filters are transforming the field of dust collection. They are increasingly used to replace woven and felted filter bags in existing pulse-jet and shaker collectors. In some powder and bulk handling applications, replacing existing bags with cartridges can increase total airflow by 50 percent. This factor, combined with their small size and low cost, have made cartridge filters the preferred choice in chemical, pharmaceutical, and other applications.
