Vombaur: Textiles for filtration processes
The tubular filters from Vombaur ensure an even filtration process, a homogeneous filter cake and an optimal filtration result.
The heart of every filtration system is the actual filter itself. The filter materials most widely used by Vombaur include textiles, such as round woven tubular filters and woven tapes. As a particularly fine and flexible medium that is permeable to fluid, these materials are often used in the chemical industry.
Quality, safety and environmental aspects have always played a special role in the chemical sector – and these requirements and standards will continue to rise. Filter systems that are used for chemical production must be state-of-the-art. Filtration must be safe, precise and variable with regard to the finest nuances of separation. The filtration product should be gently separated.
At the same time, the durability and longevity of the medium are also important – especially when it is exposed to high mechanical loads, e.g. as a result of frequent backwashing. From microfiltration processes used in the production of pharmaceuticals to oil filtration in petrochemical applications: a high-tech filter medium, such as the seamless round and shaped woven filter media from narrow textile manufacturer vombaur, is required.
Uniform surface properties
The production method employed by Vombaur ensures the tubular filters do not have any seams or beading. They therefore exhibit identical surface properties all around and over the entire length: there are no fluctuations in terms of shrinkage behaviour or material thickness. The defined flow rate is thereby ensured at every point. The level of resilience is extremely high throughout.
The respective process requirements stipulated by customers determine the product development phase. The Vombaur team selects the fabric type, weaving technique, finishing and material of the tubular filters and woven tapes, depending on what the filter needs to achieve.
The high-performance textiles are manufactured from polyester, polyamide, polypropylene, PTFE, metallic yarns and many other high-tech fibres.
