CARTRIDGES
With our 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.
POLYESTER (PETP) FILTERING CARTRIDGE
The polyester filtering cartridge is composed of a tubular support screen of AISI 316 Stainless Steel or SAF 2205 with filter tissue, generally in polyester (PETP). 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.

MULTI-LAYER POLYESTER (PETP) FILTERING CARTRIDGE
The multilayer filter cartridge with polyester tissue is composed of a polyester filter medium (PETP) mounted between two baskets in stainless steel AISI 316 or SAF 2205, which mechanically protect the filtering tissue.
To mechanically protect the filtering 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 for cleaning the fabric itself.

STAINLESS STEEL FILTERING CARTRIDGES
The filtering cartridge of AISI 316 Stainless Steel or SAF 2205 can be composed of a single tubular perforated sheet that makes up the basket, or of a filter screen welded to one or between two tubular support screens, all of AISI 316 Stainless Steel or SAF 2205.
The multi-layer system allows to have a cartridge with high resistance to wear, strong and durable.
This solution is available with a filtration range between 5000 microns and 50 microns.
High resistance of the filtering baskets: each filtering basket is obtained from steel sheet suitably punched with 8mm x 8mm and 2mm thick square mesh (68% free area), the flaps of the punched sheet remain full to be welded together after calendering. In this way, the basket has a continuous welding bead that joins it to obtain a strongly robust basket along its entire length.

STAINLESS STEEL FILTERING 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, SAF 2205 or SAF 2507 stainless steel.
They can be composed of a metallic filter screen welded to one tubular support screens, all of AISI 316 Stainless Steel or SAF 2205. 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.
FILTERING MEDIA
Our standard filter cartridges are divided into two macro categories: polymeric tissues and metallic cloths.
POLYESTER (PETP) FILTER TISSUE
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.
The filtering fabrics are of 2 types:
Single layer
For single layer fabrics refer to the table for more information on the available fabrics and the percentage of free area.
Multilayer
Multilayer (ML) fabrics are filtering fabrics obtained with a particular design which makes the filtering media much more mechanically resistant.
The fabrics of the ML series have a high permeability and thanks to their construction characteristic they create a highly draining filtration cake.
The fabrics are indicated with abrasive solids and in the presence of high-pressure differences on the filter medium.

METALLIC SCREEENS
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.

FILTER BAGS & COVER BAGS
The filter bags we use are made of polypropylene and / or polyester felt and nylon mesh, they are designed for the filtration of water, drinks and non-hazardous liquids in general and are therefore widely used in particular in the treatment of water for drinking use and industrial, in the food sector and in the chemical and petrochemical industry.
It is possible to wrap the filter bag externally with an OilRepellent™ tissue bag which acts as a safety barrier to keep the oily contaminated spills from the bag.
