What is a filter bag cage? The filter bag cage, also known as the filter cage, is the key component of industrial dust collectors.  It is a skeleton for supporting the filter bag and its quality plays an important role in optimizing filter bag performance and extending the filter bag working life. Filter bags must fit snugly around the cage to keep stretching, preventing wear on the bags, but must also be flexible enough to remove for cleaning.

AGICO is a professional cement equipment and cement plant spare part manufacturer. With our advanced production equipment and testing methods, we provide filter cages that fit most baghouse applications and offer a selection of circular or oval cages depending on customers’ requirements. Many different raw materials, lengths, and configuration options are available. In addition, depending on production needs, we can implement various anti-corrosion treatments on the surface of the filter bag cage, such as electroplating, coating, painting, and so on.

Filter Cage Parts

The filter bag cage is mainly composed of vertical wire, horizontal wire, cage top, cage bottom, cage joint, and cage venturi.

Vertical Wire & Horizontal Wire

Filter cages on the market are mostly consisted of 10, 12, or 20 vertical wires. The number of vertical wires depends on the application purpose and the texture of the filter bag. The filter cage with 20 longitudinal wires is generally used to support filter bags that require strong support, like fiberglass woven bags. As for the cage with 10 or 12 vertical wires, it is more suitable for filter bags with lighter weight.

The existence of the horizontal wire is to enhance the overall stability and support strength of the filter cage. It is equally welded around the circumference of the cage. The spacing distance between two horizontal wires is generally 150-200mm.

Cage Venturi

The venturi is a component used to accelerate the pulsed air in the filter bag for more efficient cleaning. It has a variety of designs that can be applied in all-diameter filter cages. For different applications, it can be made of aluminum, carbon steel, galvanized and stainless steel. Cage venture is optional. Typically, the longer the filter bag, the more important it is to have a venturi.

Cage Joint

Cage joint is a connector between two filter cages for supporting extra-long filter bags. AGICO offers different styles of cage joints for customers to choose from.

Woven Wire: commonly used due to easy installation;

Double Ring: widely used in air manifolds for treating industrial dust and flue gas;

Double Groove: firm connection, strong support, smooth edge, reducing the rate of filter bag damage;
