Ahlstrom line increases filtration capacity
Cummins sells noise control subsidiary
Ahlstrom is to redirect capacity on one of its current nonwoven lines to make it available for filtration materials.
Cummins Inc is to sell Universal Silencer Inc (USI) to the Stirling Group. USI, which currently forms part of the Cummins Filtration business, provides noise and emissions technology for large diesel and turbine engines, compressors, blowers and other air movement equipment.
The 4.5 m wide line currently manufactures medical, apparel and a variety of other industrial nonwovens. The project aims at freeing up additional capacity in order to produce materials using waterbased chemistry destined for the transportation filtration markets.
News from McIlvaine The market for cartridges for liquid purification will climb to US$21 billion in 2012 up from US$15 billion in 2007, says McIlvaine’s Cartridge Filters: World Markets report. Carbon filters will reportedly lead the market, taking US$6,904 billion in 2007 and US$10,165 billion in 2012. They are followed by membrane and metal cartridges. The residential market in Asia will lead the way with growth to over US$2 billion by 2012 up from US$1.3 billion this year. McIlvaine says that there are more than 10,000 companies manufacturing cartridge filters worldwide, with smaller numbers of media manufacturers. A number of large companies such as GE have entered this market place and consolidation for companies such as Pentair have also created large players in the field. Nevertheless, the market is fragmented by geography, application, and product types. In its Fabric Filter and Elements World Markets report, McIlvaine predicts that fabric filter revenues will increase at 6% per year over the next five years. This huge growth rate will be due to the switch from electrostatic precipitators to fabric filters. Power and cement plants are now required to achieve greater than 99% dust removal and the fabric filter is considered to be the most efficient device for particulate control. www.mcilvainecompany.com
“This line has an excellent track record of producing high quality products for the nonwovens industry utilising water based chemistries, and we are confident it will be able to do so for the filtration industry,” said Randal Davis, senior vice president, filtration at Ahlstrom. The new capacity will be available in the first quarter of 2008. www.ahlstrom.com
The newly formed Stirling Group will include other key members of USI’s management team including current general manager Randy Eppli.
“We believe this is a very good day for the future of the Universal Silencer business, customers and employees,” said Eppli. “USI has a strong foundation in acoustics, filtration and emission control solutions for our customers, and our new investors are very supportive of investing in this foundation for the long-term growth of the business.” www.cummins.com
