Maximize the performance of your small or mid-sized container-topped dust collector with an AFF oversized filter bag -- the most cost-effective way to increase suction and reduce the amount of dust in your shop. Replace that ineffective 30 micron woven cloth filter bag with our singed felt bag and get enough fabric surface area to exhaust all the air (CFM) without producing back-pressure. Regain maximum fan output and still contain virtually all the finest dust. All bags listed here are rated for twice the fan CFM and will continue providing great suction and very fine dust filtration even after the fabric gets dirty.

American Fabric Filter Co. custom makes bags of all sizes and shapes. Years of experience have taught us that the designs suggested here work best for general applications. For commercial duty applications, we strongly recommend using 12 oz. and 16 oz. felts and making the bag one and two sizes larger respectively. Please call us to discuss your specific needs.
