Extruded diamond mesh (bi-planar) netting features excellent dimensional stability and rigidity because the joint structure is 'welded' together. Polypropylene (PP) is the most common resin in filtration applications due to its inert nature and regulatory approval for both food contact and pharmaceutical applications. Some configurations are also available in polyethylene (PE) or polyester (PBT).
Diamond mesh netting facilitates the flow of fluids or air in filtration applications by serving as a feed spacer between layers of filter media. The bi-planar construction creates flow channels across the filter medium.
The largest application for this flow channel function is with spiral filter elements. The diamond configuration is used in cross-flow applications to provide drainage and as a spacer net. Due to its high profile strand construction it can provide support for the medium with minimal contact with the substrate, which reduces the effects of binding. The flow channel height and depth can be designed for various types of filtration streams and flow rates. While this is commonly used in spiral filter elements it is also used in other membrane-related filtration applications as well.
Extruded polypropylene netting is also available in square (mono-planar) and rigid tubular mesh configurations. For higher temperature applications choose from a variety of Nylon square mesh nets.
