Air filtration - HVAC
1,6 m wide line producing PA6 nanofiber layer as part of three-layer composite used for HVAC applications. Final pleated gradient filtration media designed to withstand tested per ISO16890 protocol. Nanospider™ production line configured for low basis weight coating at high linear speed.
Air filtration - Gas turbines
Complete production line with two spinning unit capacity, delivered to filter media and final filter manufacturers. Elmarco's turn-key solution included entire technology integration and peripheral delivery. A light nanofiber layer deposited onto cellulose filter media ensures target filtration efficiency at a significantly lower pressure drop with good cleanability.
Nanospider™ electrospinning technology is a patented, needle-free high voltage, free liquid surface electrospinning process. The technology is based upon the discovery, that it is possible to create Taylor Cones and the subsequent flow of material not only from the tip of a capillary, but also from a thin film of a polymer solution. The technology enabled Elmarco to build industrial scale production equipment with out nozzles, needles or spinnerets.
High productivity & scalability
High fiber diameter and web uniformity
Economical operation and easy maintenance
Flexibility in used polymers and substrates
Nanospider™ electrospinning technology allows the production of nanofibers from polymers solved in water, acids or bipolar solvents and is suitable for the production of organic high quality fibers. This versatile technology is easily adapted to a variety of process parameters for the optimization of the specific properties of the produced nanofibers. |
Nanospider™ technology uses simply shaped electrodes, has no parts easily clogged (in comparison to needle-type electrospinning) and is generally mechanically simple. |
The numbers of fibers per machine width is given by the distance of the Taylor cones. Nanospider™ free liquid surface electrospinning lets natural physics define this distance, rather than using individual needles. This allows higher fiber packing density and thus an increased productivity as well as better fiber homogeneity and more consistent web morphology. |
