Although there are only three basic types of baghouses - shaker, pulse, and reverse air – there are hundreds of different styles of bags. Baghouse filters vary in diameter and length from manufacturer to manufacturer, and from model to model with some bags collecting dust on the inside, while others collect dust on the outside. Bags may be placed over a cage, mounted in a plenum, or suspended from a hanger. The one characteristic all baghouse filters share is that they require periodic replacement to maintain top performance. AFF manufactures all styles of replacement filters from a selection of fabrics suited to address specific situations. The company can cross-reference most filters or duplicate your sample to provide an exact match and insure a perfect fit.
