Abstract
US Global Aerospace Inc has introduced a range of virus and pathogen filters for aircraft environmental control systems (ECSs) and heating, ventilation and air conditioning (HVAC) systems for hospitals and buildings. With the ability to capture particulates down to 0.05 μm, the company will be targeting the product line at an air industry increasingly concerned about viruses such as severe acute respiratory syndrome (SARS).
This is a short news story only. Visit www.filtsep.com for the latest filtration industry news.
The introduction of the Nanofilters product line has also prompted the firm to change its name to US Global Nanospace Inc.
The Nanofilter range uses technology initially developed by Y2 Ultra-Filter Inc for NASA long-duration space flight applications to provide ultra-fine particulate matter air purification. US Global has integrated porous Nanofilter media into the design, which is then enveloped with an electronic field. The electronic field causes airborne particulate matter to move in a churning motion perpendicular to airflow direction without ionization, thereby enhancing the
London/Van Der Waals force interaction. The company said this results in an air filtration system that efficiently captures bacteria, viruses, smoke, dust, odorants and other particulate matter down to 0.05 μm.
US Global has the exclusive world rights for the Ultra-Filter technology for all aircraft applications worldwide and will offer Nanofilters for long-range commercial aircraft including the Boeing 7X7 series, Airbus A3X0 series and the MD 11.
“The common high-efficiency particulate air (HEPA) filters used in aircraft today do not provide the sub-micron filtration required to protect the public from re-circulated SARS and many other airborne viruses,” said John Robinson, chairman and CEO of US Global Aerospace. “Our Nanofilter is designed to effectively and efficiently filter airborne viruses such as Respiratory Syncytial Virus, a common cause of pneumonia with a particulate size of 0.09 μm. The SARS virus is thought to be a member of the Coronavirus family, which range in size from 0.06 to 0.22 μm. Our Nanofilter is also designed to deliver a 35% reduction in energy consumption and a service life cycle cost one-half of HEPA filters.”
US Global also has non-exclusive rights for commercial applications in Hong Kong and China and is seeking to begin producing replacement HVAC filters for hospitals treating SARS cases there in the coming months.
