American Fabric Filter (AFF) offers custom-designed cartridge overbags that help prevent dust from bridging across the filter pleats, as well as help keep the cartridge from blinding. These custom overbags are also designed to make pulse-type cleaners more effective, and are manufactured from high-quality nylon monofilament. Adding a bungee cord in the hem allows for quick and easy installation. The overbags are reusable, and custom sizing ensures a perfect fit. AFF offers free design assistance and quotes.
