We produce filter bags in sewn and welded versions according to your specifications, from:
We manufacture mesh filters with an O-ring made of metal or elastomer; with a flange made of polyamide, polypropylene, or stainless steel and a base; and with a metal flange without a base.
A welded mesh filter offers significant advantages over other filter bags, particularly for mesh sizes from 1 μm to 500 μm.
Welding allows filter fabrics of the same or different structure to be joined securely without the use of adhesive.
The result is a stable, load-bearing seam that minimizes the risk of pinhole perforations.
In addition, this creates a completely tight seam, preventing particles from escaping.
This method ensures long service life and high reliability of filtration performance, particularly in demanding industrial applications where absolute tightness combined with the longest possible service life is essential.
Filter bags and mesh filters are essential components across various industries, ensuring efficient filtration of solids and particles.
Here, filter elements play a crucial role in purifying liquids and removing particles to ensure product quality and safety.
They are frequently used in the filtration of beverages, sauces, oils, and other liquid products.
In the pharmaceutical industry, the highest purity standards are essential to ensure the quality and safety of manufactured products.
When manufacturing pharmaceuticals, it is essential to exclude contamination and maintain a sterile environment. Special filter inserts made of materials such as polypropylene, polyester, and PTFE are used for this purpose.
These materials are characterized by their chemical resistance and fine pore structures, which reliably retain particles and microorganisms. The mesh filters prevent unwanted substances from entering production and ensure that products meet the strict requirements of pharmaceutical guidelines.
The chemical industry uses filters in a wide range of processes to ensure purity and efficiency. These include the filtration of chemicals, solvents, and reaction products that frequently occur in production. Mesh filters remove unwanted particles, solids, and contaminants, improving the quality of the end products.
A wide range of filter fabrics, such as polypropylene, stainless steel mesh, or PTFE, makes it possible to tailor filters to the specific chemical properties of the substances involved. This ensures that the filters withstand the aggressive properties of many chemicals and remain durable.
In the paint and coatings industry, mesh filters and special filter bags are specifically used to ensure high quality end products. During the manufacturing process of paints and coatings, it is essential that particles, lumps, and other contaminants are reliably removed.
Thanks to their fine-mesh structure, industrial filter bags ensure that only the desired particle sizes pass through. These industrial filters offer additional flexibility by enabling easy handling and quick cleaning. This results in smooth surfaces and even color distribution, meeting the industry’s high quality standards.
Filter bags and mesh filters are indispensable components in industry, ensuring efficient filtration across a wide range of applications and thereby improving product quality, safety, and efficiency across numerous processes.
Production takes place in several stages, beginning with the development of prototypes to verify functionality and efficiency. After successful testing, small batches are produced to ensure practical suitability under real-world conditions. Once validation is successful, large-scale production follows to meet industry demand on a large scale.
Prototype development involves selecting suitable materials, designing the filter structure, and adapting it to the specific requirements of the industry. Tests are also carried out to evaluate performance under various conditions.
In small-batch production, successful prototypes are manufactured in limited quantities and tested in industrial environments. This phase makes it possible to identify any weaknesses and further optimize the filter elements.
Following successful small-batch testing, large-scale production begins to meet industry demand. Manufacturing uses efficient production methods, with strict quality controls ensuring that every filter bag produced meets the highest standards.
These filter elements are made from stainless steel mesh 1.4301 or 1.4571, with mesh sizes ranging from 1 μ to 2000 μ.
All components, as well as every development and production step, undergo continuous testing to guarantee the proven quality of “made by Lechleiter”.
