The material to be collected determines the filtration technology. During industrial production processes e.g. mechanical material treatment, thermal processing or painting and finishing, air pollutants of different kinds arise.

The system requirements - quality and quantity, the physical-chemical nature and the aggregative condition determine the appropriate system.

The airflow quantity, the emission rate according to each process, the airflow velocity and the airflow direction are the most important factors which have to be considered when planning the installation.

To find the optimum filtration method with all possible advantages, a systematic realization of the project is necessary to get maximum industrial and operational safety, clean air and pollution control.

The SINBRANŽ filtration technology

Recent developments in air filtration systems utilizing sub-micron membrane technology are particularly well suited to improving plant air quality in laser and plasma cutting applications. Increasing air quality health standards require a system solution to the hazardous sub-micron dust generated by laser and plasma cutting in order to maintain a safe and clean working environment.

Developed to meet the rigorous European manufacturing facility air quality standards, SINBRAN is a new, highly efficient filtration material, which is especially appropriate for filtration of dust created during laser and plasma cutting applications. The material is composed of a rigid substrate and a PTFE membrane laminated on the surface. This combination allows for a new approach in filtration technology, offering the advantages of both rigid body filtration and membrane filtration effect.

SINBRAN filter material is made up of two main components, the supportive substrate and a membrane layer on the outside. The rigid body of the filter material consists of sintered polyethylene. It is highly porous, allowing the cleaned air to penetrate without high pressure loss. The material is capable of withstanding high mechanical stress, thereby protecting the membrane from mechanical impact, which is most important during cyclic cleaning of the filter surface.

The active filtration layer is a GORE PTFE membrane, which is laminated on the surface of the rigid body structure. Due to its sub-micron porous structure a nearly complete surface filtration can be achieved, which is the goal of particle filtration. Even the smallest particles are prevented from permeating the filter body. It has been proved by emission measurements that residual dust concentrations on the clean gas side are lower than 0.1 mg/m3.

Considering the percentage of certain particle sizes removed, the following results were achieved with the SINBRAN filter:

This high efficiency is especially important in laser and plasma cutting applications, where 100% of all particles are smaller than 10 micrometers.

It has been proved that in comparison with conventional filters SINBRAN achieves lower differential pressure in the filter media, resulting from the high level of surface filtration. Conventional filter elements are based on the depth filtration principle, accumulating dust inside the filter media. With SINBRAN, the separated particles stay on top of the membrane and are not able to enter the filter body. This guarantees easy dust removal and high online cleaning.
