Pleat supports are used to create a support structure for the filter media. They keep the media in its intended shape, allowing particles to easily pass through while also preventing any clogging or blockage.
GESSNER with its netting solutions Naltex™ and Conwed™ is a leading supplier for filter elements. Our premium quality nettings are designed to provide superior performance in a range of filtration industries, including automotive, industrial processes, food & beverage, air & liquid. Used as pleat support, membrane support, permeate carrier, flow enhancement, screening layer, and feed spacers our high-performance products are manufactured to withstand extreme temperatures, chemicals and abrasion while still providing maximum filtration efficiency.
Naltex™ & Conwed™ nettings feature a lightweight construction that enables users to achieve greater surface areas without increasing weight or compromising strength and durability. Both materials can be used as pleat supports, providing customers with the necessary support structure for their filter media. This additional layer of protection ensures optimum performance by preventing clogging or blockage from occurring within the filters. With these specialized netting products from GESSNER, customers can enjoy improved results in their filtration processes while also reducing costs associated with waste removal and product contamination.
For 70 years Naltex™ Extruded Netting, our premier diamond net, has delivered high-performance results in environments needing filtration, separation, and protection.
The biplanar configuration of Naltex™ Extruded Netting allows excellent flow as feed water spacers in Reverse Osmosis (RO) applications. Specific strand alignment achieves the turbulence needed to protect and maintain the systems membranes. In addition to RO applications, Naltex can be used in many industrial applications including bags and racks for food processing and plastic mesh for protection and packaging applications.
Naltex™ diamond mesh continues to evolve as our engineers improve the process of extruding through counter-rotating die heads. Over the years we've introduced nets with new resins, varied strand count and cross section, and a range of strand angles, offering customers different looks, feels, strengths and additional functionality. We custom-develop extruded netting to meet your specific industrial performance requirements for demanding applications in the healthcare, filtration and industrial markets.
Our extruded Conwed™ square netting is manufactured through a single-step continuous extrusion process that yields a plastic netting material with integral joints. Our resins and formulations vary depending on the final product application and the performance requirements set by our customers
Conwed™ Square Netting products are manufactured via a continuous extrusion process that yields plastic net featuring an integral joint for stability. In a secondary process, Conwed nets can be oriented to provide a lightweight but high strength netting for containment and reinforcement. We use a variety of resins to meet our customers’ application requirements to ensure superior protection, containment and separation.
Historically, our nettings were supplied by corporations such as SWM International, DelStar Technologies, and Conwed. However, following the 2022 merger of SWM & Neenah to become Mativ, these materials have now become products under the GESSNER umbrella, a brand of Mativ.
