Examples of our work :

- Cartridge with folded paper media and an outside frame made of expanded metal, a perforated inner metal body, pressed cups or ones pushed out at both ends with and without sealing gaskets. The folded filter element reduces filter surface compared with a smooth filtration element.

- Cartridge with a folded cloth filter media crimped onto the end rings, with a perforated metal inner frame. The advantage of crimping is that sealing is ensured with no need for glue. A continuous weld that sandwiches the folded media between the ring and a ferule also eliminates the need for glue and is easier to apply for small quantities.
