Top-Pleat Pleated Filter Cartridges

Pleated filter cartridges are surface filters for removing hard, non-deformable particles from a liquid stream. They feature a large filter area, a high dirt holding capacity and consequently a long filtration lifetime.

The sharp cut-off characteristics created by the filter media ensures dependable and highly efficient particle removal at the designated micron rating. Pleated cartridges are therefore widely used as particle size classification filters, as well as being utilised as either final filters or as protection for expensive membrane filter cartridges.

Top-Pleat Series

The Top-pleat series is one of the finest ranges of pleated cartridges on market. Consisting of 4 layers of the highest quality filter media, they provide exceptional filter efficiency and lifetime. The constituent filter media has thermobonded fibres to prevent fibre and contaminant release.

The Top-pleat PP is constructed from 100% polypropylene melt blown microfibre media and has a wide range of application suitability. Polypropylene is especially compatible with applications which require filter cartridge sterilisation with caustic soda. They are rated at 95% efficiency at the designated micron rating.

The Top-pleat GF is constructed from borosilicate laboratory grade borosilicate (glass fibre) and incorporates polypropylene pre-filter and final filter layers. Borosilicate is a hydrophilic filter media, providing superior flow and lower pressure drops compared to polypropylene media. The 1 micron version is ideally suited to applications requiring Cryptosporidium and Giardia Cyst removal (certified to NSF/ANSI standard 53 for Cyst reduction). Borosilicate has a natural charge (Z potential) to capture organic matter and retain colloids. Topleat GF cartridges have an efficiency of 99.98% at the designated micron rating.
