Investing in Quality Filter Cages and Venturis for Long-Term Savings and Performance


Filter bag cages and venturis might not always steal the spotlight, but they are the heroes behind efficient and reliable dust collection systems. Neglecting the importance of these components can lead to a cascade of operational and compliance issues in your facility. At, we understand the critical role played by filter bags, cages, and venturis in maintaining a top-notch dust collection system working perfectly. Let’s delve into why investing in quality components like these is a smart decision for your industrial operations.

The Crucial Role of Filter Cages

Filter cages might seem like simple components, but they are essential for the proper functioning of your dust collection system. When filter bags don’t fit snugly onto the cages or when cages are not replaced when needed, it can compromise the entire system. Neglected filter bag cages are often the root cause of many operational problems in industrial settings.

Cage Types

The purpose of a baghouse cage is to provide support for filter bags to stay open during the dust collection cycle.



Common Cage Styles

Common baghouse cage styles include rolled top (top load baghouses) and split collar (bottom load baghouses). Options include galvanized steel, stainless steel, or epoxy coated. Cages can also have integral or drop-in venturi for improved bag cleaning.

One key feature is the precise fit between the filter bags and the cage, ensuring proper adhesion and a long service life. Quality filter cages are built to withstand cleaning cycles, bag changes, abrasive materials, high temperatures and many other environmental conditions they might encounter.

Additionally, filter cages should withstand the pressure exerted by the filter bag during the particulate collection cycle. They are also engineered to provide uniform support along the entire length of the filter cloth.

Regardless of design, each cage should adhere consistently to its specifications. This includes maintaining the correct diameter, total length, and other tolerances. The technologies we employ at ensure your cages are made to spec, ensuring a proper fit between the filter bag and the cages and resulting in optimal cleaning performance. Our dust collector cages can be made to fit existing collectors from any baghouse manufacturers such as Astek, Gencor, Flexkleen, Mikropul, Wheelabrator, etc. We can also manufacture uncommon and specialized cage designs as required.

Understanding the Significance of Venturis

In some pulse jet collectors the venturi, or diffuser, plays a pivotal role. Its function is to accelerate compressed air at the center of the cage, optimizing the cleaning of bag filters. Venturis are made in a variety of materials including aluminum, carbon steel, galvanized and stainless steel.

Venturi Design

The venturi design changes the distribution of the cleaning pressure in the vicinity of the filter bag mouth, effectively reducing the energy consumption as well as reducing the dust emission concentration of the baghouse.
