At Conwed, we design and manufacture high‑performance nettings and mesh materials that improve durability, efficiency, and consistency in both air and liquid filtration systems. Our pleat support solutions ensure that filter media maintain optimal shape, flow characteristics, and lifespan, even under demanding conditions.
Why Pleat Support Matters
Pleated filters depend on structural stability to deliver peak performance. Without proper support, pleats can collapse, pinch, or restrict airflow — leading to increased pressure drop and reduced filter life. Conwed solves these challenges with scientifically engineered nettings and films that create defined flow channels, prevent pleat deformation, and enhance mechanical stability.
Our Three Core Pleat Support Technologies
Naltex™ Diamond Nettings
Conwed’s Naltex™ diamond‑shaped nettings are a leading solution for both air and liquid filtration applications. Their unique bi‑planar structure creates stable, well‑defined flow channels, preventing pleat pinching and extending the lifespan of pleated filters to maintain consistent filtration efficiency.
Conwed™ Square Nettings
Our Conwed™ square nettings are engineered through a continuous extrusion process, producing integral joints that deliver exceptional strength and rigidity. When further oriented in a secondary process, these nettings become both lightweight and robust, offering reinforcement and containment in complex filter designs.
Their mechanical strength makes them suitable for applications requiring long‑lasting support without excessive weight.
Delnet™ Apertured Films
Delnet™ apertured films offer outstanding flexibility and customization. Created through a specialized combination of extrusion, embossing, and orientation, these films provide extremely thin support layers. By varying the process parameters, an infinite variety of configurations can be created to meet our customers’ requirements.
Built for Harsh and Demanding Conditions
Our pleat support portfolio includes materials engineered to withstand extreme environments, including:
- High temperatures
- Corrosive fluids
- Chemically aggressive atmospheres
This robustness ensures that filter elements maintain optimal stability and performance even in the most challenging industrial settings.
Enhancing a Wide Range of Filtration Applications
Our pleat support materials are designed to optimize efficiency and longevity in liquid and air filtration across a wide range of applications.
Because of the unique mechanical benefits of Naltex™, Conwed™, and Delnet™, filter manufacturers can tailor the exact level of support required for their specific media and performance targets.
