Leaf Filter

For several decades, Sefar is the leading supplier of covers, bags and candles for all types of horizontal and vertical pressure and vacuum leaf filters, such as Cricket, Diastar, Kelly, Tamaris, Miningtech  Moore, Outotec and others. Leaf filter bags are developed in close cooperation with leading equipment manufacturers as well as directly with end users, paying attention to the specific requirements of the filter equipment and separation application.

 

Fabrication solutions

 

Finished bags and covers for leaf filters from Sefar are equipped with options that significantly simplify the installation of the products. Most of our products have welded seams, which ensure minimal product loss since there are no stitching holes.

 

A newly developed closing system (patent pending), for the mineral industry especially, facilitates the installation of leaf filters which reduces operational expenses and the risk of leakages.

 

Sefar has developed dedicated yarns and filter media to withstand strong alkaline process conditions at operating temperatures up to 110 degrees Celsius. Our multichannel bags feature highly uniform dimensions thanks to an automated fabrication process from cutting to welding and channel sewing on a special sewing automate. Special thread is used for sewing and a highest-class fabric allows for smooth installation and perfect tightness on the collector.
