Filter pockets are flat textile filter elements used in industrial dust collection and dedusting systems. They are manufactured according to the dimensions, filter medium and finishing requirements of the existing filtration system.
Solana manufactures filter pockets and multi-pocket bag filters in its own workshop in Belgium. With a wide range of filter media available, the construction can be adapted to the type of dust, operating conditions and required filtration properties.
Several common sizes and configurations can be ordered directly through our webshop. Other filter pockets are manufactured completely to customer specifications.
Filter pockets are flat filter elements used in industrial filter housings and dust collection systems. The broader term filter bag is also sometimes used for this type of textile filter element.
Depending on the installation, the filter medium is supported by a frame or another internal structure. Correct dimensions and sealing are important to prevent unfiltered air from bypassing the filter medium.
For reliable sealing, filter pockets can be fitted with a felt cuff, sealing cord or other customised finish.
Filter pockets are used in applications including:
The appropriate filter medium depends on factors including:
Different materials and surface treatments are available depending on the application.
Every filtration system has its own dimensions, mounting system and technical requirements. We therefore manufacture our filter pockets according to the specifications of the existing installation.
We supply replacement filters for systems from manufacturers including:
We can also manufacture custom filter pockets for older or less common filtration systems.
If the original technical data are no longer available, an existing filter pocket, clear photographs or a technical drawing are often sufficient to determine the required construction.
Contact us for technical advice or a custom quotation.
In addition to individual filter pockets, we manufacture multi-pocket bag filters.
In this construction, several filter pockets are combined into a single filter element. This creates a larger filtration surface within a compact construction.
Multi-pocket bag filters are also manufactured according to the dimensions and technical requirements of the existing filtration system.
The choice of filter medium has a major influence on filtration performance and service life.
Depending on the application, filter media can be selected for:
When selecting the filter medium, we consider not only the base material but also properties such as weight, thickness, air permeability, temperature limits and surface treatments.
Our filter pockets are manufactured in our own workshop. Different processing techniques are used depending on the material and construction.
Filter textiles can be cut to size using laser technology, providing accurate dimensions and clean edges.
With suitable thermoplastic filter media, seams can be thermally sealed instead of stitched. This avoids needle perforations in the seam.
When sewing is technically the most suitable method, the construction and seam finish are adapted to the filter medium and application.
During production, we check factors including the dimensions, material selection and finish of the filter elements.
For certain fine or sticky dusts, suitable precoating can help protect the filter medium and facilitate the release of the filter cake.
Depending on the filter material, contamination and condition, used filter pockets and multi-pocket bag filters can in some cases be professionally cleaned or repaired.
A filter pocket is a flat textile filter element used in industrial dust collection systems. The broader term filter bag is also frequently used for this type of filter.
However, filter bag can refer to several different filter constructions. It is also used for tubular filter sleeves and filter bags.
The correct filter construction depends on the filtration system, mounting method and application.
A multi-pocket bag filter combines several filter pockets into a single filter element. This provides a larger filtration surface within a compact construction.
For an accurate replacement, we preferably need the dimensions, existing filter medium, finish, and brand and model of the filtration system.
A technical drawing, clear photographs or an existing filter pocket can also be used as a reference.
The correct material depends on factors including the type of dust, operating temperature, moisture, chemical exposure, required air permeability and cleaning method.
Solana can help select the appropriate filter medium for your application.
Yes. Because we manufacture our filter pockets to order, we can also produce filters for older or less common filtration systems.
If technical documentation is unavailable, we can often work from an existing filter pocket, photographs, dimensions or a technical drawing.
