Sinter filters are used in systems with the pneumatic conveying of fine powders and bulks materials in the plastics and chemical industry. GORE® SINBRAN® filter elements are made of PTFE and PE. They are also suitable for use in systems, which have to be cleaned frequently. They can be cleaned wet or dry. A easy to clean flange connection prevents moisture penetrating the cavities between the filter plate and the filter. This new flange connection has resulted in a simplified design of filter plate. Surface filtration prevents the product penetrating into the depth of the filter, ensuring that it remains easy to clean.
