A support cage, also known as a filter cage or baghouse cage, provides the internal support structure for a filter bag, filter sleeve or filter pocket. The cage keeps the filter media fully open during filtration and withstands the mechanical forces generated during filter cleaning.
Damaged, deformed or corroded cages can result in:
Timely replacement of damaged support cages helps prevent these issues.
A venturi is primarily used in pulse-jet dust collection systems. The venturi helps direct the compressed air pulse into the filter bag more efficiently, improving the cleaning of the filter media.
A properly designed venturi contributes to:
For applications involving fine or sticky dust particles, the use of precoating powder may further improve filter cleaning performance.
We supply support cages in various materials:
Available surface treatments include:
The most suitable material depends on operating temperature, humidity, corrosive conditions and mechanical loads.
Support cages are available in different shapes and constructions:
The correct configuration depends on the dimensions of the filter element, the design of the filtration system and the operating conditions.
SOLANA supplies support cages and venturis for a wide range of dust collection systems and filtration units.
We can supply support cages for installations from manufacturers such as:
We can also provide suitable replacement cages and venturis for older or less common installations.
Are the original technical specifications no longer available?
An existing support cage, photographs, dimensions or a technical drawing are often sufficient to identify a suitable replacement.
Yes. The terms support cage, filter cage and baghouse cage are often used interchangeably. They all refer to the internal support structure that keeps a filter bag, filter sleeve or filter pocket open during filtration and cleaning.
A support cage supports the filter bag, filter sleeve or filter pocket and prevents deformation during operation and cleaning. A venturi is a separate component that optimises compressed air flow in pulse-jet systems and improves filter cleaning efficiency.
Damage, corrosion, deformation or broken wires can negatively affect the performance of the filter media. Timely replacement helps prevent premature filter wear and reduced filtration efficiency.
Yes. In many installations, the venturi can be replaced without replacing the complete support cage assembly.
The most suitable material depends on operating temperature, humidity, chemical exposure and mechanical loading. SOLANA can assist in selecting the most appropriate material for your application.
We can help you select the most suitable support cage or venturi for your installation, including situations where the existing cage is damaged or no longer performs correctly.
