Hollingsworth & Vose (H&V) is at Filtration 2008 in Philadelphia, PA this week at Booth 202 promoting its new Nanoweb advanced nanofiber technology for air and liquid filtration and performance barrier nonwoven applications.

H&V’s new Nanoweb technology provides a microporous structure with unparalleled process control and durability. The fiber diameter distribution and layer thickness can be formulated to deliver greater performance across many applications. “H&V’s new Nanoweb Advanced Nanofiber Technology is highly customizable and offers improved material processability and longer life,” said David von Loesecke, vice president and general manager of H&V’s Engine & Industrial Filtration. “It has superior chemical compatibility with no extractables or leachables, achieves advanced efficiency for greater performance with total cost reduction and increases energy savings.”

Applications include liquid filter media (in life sciences, food/beverage and process liquid), air filter media (dust collectors, HVAC, gas turbines and computer disk drives) and performance barrier nonwoven (thermal/acoustical insulation, hypoallergenic bedding, waterproof breathable fabrics, energy storage, etc.).

When added to standard media, Nanoweb advanced synthetic nanofiber results in performance comparable to multi-layer laminates and microfiberglass-containing grades while offering the caliper and pleating characteristics of a standard media. The product is designed to significantly enhance particle capture efficiency at a minimal increase in pressure drop compared to electrospun products.

Also new from H&V is NanoWave, an extended-surface air filtration media that represents a critical breakthrough in synthetics technology. Unlike conventional charged synthetic media that relies on charge and will often lose its efficiency in use, NanoWave mechanical filtration maintains its efficiency for the life of the filter. Compared to glass mat media, its highloft design delivers longer filter life and twice the dust-holding capability. And unlike glass, ultrasafe NanoWave won’t shed fibers during processing, installation and use. NanoWave targets ASHRAE bag or panel filter applications including commercial and residential HVAC, paint spraying, vacuums, auto air, respirators and more.
