Water filter cartridges

Filter cartridges:

This technology allows you to change the degree of filtration in a very simple and economical way: all you need to do is remove the filtering fabric enclosed between the two baskets and insert the new tissue. This means that instead of replacing the entire filter cartridge, you can just change the tissue (filter media) very easily and cost-effectively.

PS POLYESTER (PETP) FILTERING CARTRIDGE

PS

The polyester filtering cartridge is composed of a tubular support screen of AISI 316 Stainless Steel (or Duplex or Titanium) with a polyester (PETP) filter tissue. This solution allows to have a filtration range from 1000 μm to 25 μm.

All our polyester tissues are available in the Nanotex™ technology version.


PSML MULTI-LAYER POLYESTER (PETP) FILTERING CARTRIDGE

PSML

The multi-layer polyester filtering cartridge is composed of polyester (PETP) filter tissue fitted between two tubular support screens of AISI 316 Stainless Steel (or Duplex or Titanium). To mechanically protect the polyester filtering tissue, it is fitted a plastic screen externally to the tissue. This multi-layer system allows to have a filtration range from 1000 μm to 10 μm and allows to protect the filtering tissue from wear caused by passage of suction pads.

SS-SSML STAINLESS STEEL FILTERING CARTRIDGES

SS-SSML

The filtering cartridge of AISI 316 Stainless Steel (or Duplex or Titanium) can be composed of a single tubular perforated sheet, or of a filter screen welded to one or between two tubular support screens, all of AISI 316 Stainless Steel (or Duplex or Titanium).
The multi-layer system allows to have a cartridge with high resistance to wear, strong and durable. This solution allows to have a filtration range from 5000 μm to 50 μm.


PCML PLEATED CARTRIDGE MULTI-LAYER

PCML

The Patented multi-layer filtering cartridge is obtained with filter tissue enclosed between two layers of polyester protective screen that gives it rigidity. Realized in 2 variants, with or without internal and external AISI 316 Stainless Steel cylinders, it is available with cleaning system with suction pads or spray nozzles and with a filtration range from 100 μm to 1 μm.

Our filter cartridges are made up of a variety of stainless steel baskets which support the filtering screens acting as filter media.

Screen supports: Our supports consist of baskets or pleated cartridges.

Baskets: Manufactured in-house, baskets are made of sheet metal and are available in a variety of thicknesses (0.8-1-2mm) and materials – such as AISI 316, Duplex (SAF 2205) or Super Duplex (SAF 2507) stainless steel. Developed internally, the manufacturing procedure for the baskets involves laser cutting the sheet metal, punching the pieces while leaving the edges free so as to allow welding after calendaring, and the bending: the result are extremely robust, high quality baskets that can reliably withstand pressure changes in the filtration chamber.

Pleated cartridges: Pleated cartridges are available in different shapes and geometries and can either consist of a polyester support for the fabric and two square-mesh baskets (inside and outside the cartridge) or a polyester support without the external basket.

Filter media: Our standard filter cartridges are divided into two macro categories: polymeric tissues and metallic cloths.

Polymeric tissues: We use polymeric materials such as polyester, nylon, polypropylene with different degrees of filtration to maximize the values of free area. All our polyester fabrics are available in the Nanotex technology version.

Please refer to the table for more information about the available tissues and open area ratios.

Metallic cloths: We can supply filter cartridges, with different degrees of filtration, for demanding applications in terms of temperature or to meet specific customer needs.

A stainless steel metallic wire cloth is the product obtained through the weaving of continuous metallic wires on automatic mechanical looms. The result is a trellis-work formed by WARP wires (i.e. those parallel to the length of the cloth) and by WEFT wires (i.e. those parallel to the width of the cloth).

The metallic cloths are different both for the size of the cloth and for the diameter of the wire used for the weaving, for the number of meshes and for the type of weaving, which can form a plain woven or plain Dutch twilled.
