H&V's new NANOWEB technology provides a microporous structure with unparalleled process control and durability. With this proprietary technology, fiber diameter distribution and layer thickness can be formulated to deliver greater performance across a wide range of applications. Our nanofibers typically range from 0.3 to 0.5 microns in size, but can be increased up to 1 micron.

The nanofiber layer can have a thickness ranging from 15 to 30 microns, and a second layer can be applied with a similar or different polymer. When supplied as a standalone substrate, NANOWEB media has a thickness of 100 to 200 microns. With its controlled versatility, NANOWEB filter media can be supplied as a coating to any nonwoven base, including glass, cellulose, or synthetic fibers, or as a standalone substrate.

Air Filter Media

NANOWEB technology can greatly improve the performance of filter media's ability to remove particulates from airstreams. This improvement can be seen in the air intake streams of dust collectors, gas turbines, motorized vehicle cabins, computer disk drives, HVAC, and high-efficiency filtration.

Various nanofiber layers can be positioned at different locations in the filter media according to the application. NANOWEB media can be positioned upstream before the macro filtration substrate to enhance surface filtration performance, or downstream of the macro filtration substrate to improve depth filtration by capturing particles within the body of the media. The strong nanofiber layer adhesion also makes NANOWEB technology ideal for pulse-cleaning applications.
