Filter sleeves, also known as filter bags, are tubular filter elements used to separate dust and fine particles from air streams in industrial dust collection systems.
SOLANA manufactures custom-made filter sleeves in its own production facilities in Belgium. Dimensions, filter media and finishing details are tailored to the application, dust characteristics and existing filtration system.
• Own production and processing facilities in Belgium
• Short lead times for custom-made and replacement filters
• Suitable for both current and older filtration systems
• Wide range of filter media and finishing options
• Production based on drawings, specifications or existing samples
• Technical advice on material selection and design

Filter sleeves are used in a wide range of industrial dust collection and air pollution control systems, including:
We stock a wide range of filter media and can supply solutions for various operating conditions, including selected materials for food-processing and ATEX applications.
The correct filter medium depends on factors including temperature, type of dust, moisture, chemical exposure, air permeability and cleaning method.
Every filtration system has its own dimensions, mounting method and cleaning principle. We therefore manufacture filter sleeves according to the exact specifications of the existing installation.
We supply replacement filters for systems from manufacturers including:
We can also manufacture filters for older or less common installations for which standard replacement filters may no longer be readily available.
If technical documentation is no longer available, an existing filter sleeve, clear photographs or a technical drawing are often sufficient to determine the required construction.
The correct finish is essential for secure mounting and effective sealing inside the filter housing. We manufacture filter sleeves in a wide variety of configurations.
Depending on the filtration system, the bottom can be manufactured with:
Other configurations are available on request.
The top of the filter sleeve can be finished with:
Filter sleeves can also be fitted with support rings along their length to keep the sleeve open during operation.
We manufacture filter sleeves for different filter cleaning systems:
The cleaning principle influences factors such as airflow direction, orientation of the filter medium and the required construction and finish of the filter sleeve.
During production, we check the dimensions, material selection and finish of the filter sleeves.
Our extensive range of filter media allows us to select the construction according to the required filtration performance, air permeability and service life.
For certain sticky dusts, precoating powder can be applied to the filter medium. A suitable precoat helps protect the filter and facilitates the release of the filter cake.
Depending on the filter medium and its condition, used filter sleeves can be professionally cleaned or repaired.
Correct installation and sealing are important for reliable operation of the filtration system. SOLANA can also install or replace filter sleeves on site.
More information is available on our Installation and Maintenance page.
The terms filter sleeve and filter bag are often used interchangeably for tubular textile filter elements in industrial dust collection systems.
However, the term filter bag can also refer to other textile filter constructions, including filter pockets and multi-pocket bag filters.
The correct construction depends on the filtration system, mounting method and application.
For an accurate replacement, we preferably need the diameter or circumference, length, top and bottom finish, filter material, filtration-system brand and model, and operating conditions.
A technical drawing, photographs or an existing filter sleeve can also be used as a reference.
The correct material depends on factors including operating temperature, type of dust, moisture, chemical exposure, required air permeability and cleaning method.
SOLANA can help select the appropriate filter medium for the application.
Depending on the material, contamination and overall condition, used filter sleeves can sometimes be professionally cleaned or repaired.
We assess whether reuse is technically and economically appropriate for the particular application.
