PORT WASHINGTON, N.Y.–(BUSINESS WIRE)– Pall Corporation (NYSE:PLL), a global leader in filtration, separation and purification, has been authorized by Eurocopter, the world’s number one helicopter manufacturer, to sell the Centrisep engine advanced protection system (EAPS) directly to EC135/635 helicopter operators. Until now the environmentally sustainable system has only been available to the operators via Eurocopter Germany. Pall Aerospace will display the EC135 Centrisep EAPS at the Farnborough Air Show, July 19-25 (hall 1, stand C129) in the UK.

The EC135 is the helicopter of choice for police and helicopter emergency medical services (HEMSs) worldwide. The virtually maintenance free, “fit and forget” Centrisep EAPS helps enable 24/7 availability and rapid launch of the helicopters. The systems can be fitted on new build helicopters or retrofitted on existing helicopters as per the instructions in Eurocopter service bulletin EC135-71-028. To order, contact Centrisep@pall.com.

“With the Pall Centrisep system, I simply remove a few small covers and I am quickly ready to fly,” commented an EC135 operator in Germany. “Without engine intake protection, it took much longer to prepare the helicopter for flight, especially on unprepared landing zones.”

“Pall’s Centrisep EAPS is the filtration standard for peak helicopter engine performance. The EC135 version has been specially designed to match the aerodynamic profile of the helicopter. The system is an excellent example of Pall’s ability to partner with OEMs to customize filtration solutions for their individual equipment needs,” said Jim Western, president, Pall Aerospace.

PORT WASHINGTON, N.Y–(BUSINESS WIRE)– Pall Corporation a global leader in filtration, separation and purification, will showcase economical and eco-friendly products and systems for the photovoltaic (PV) industry at Intersolar North America in San Francisco. The products are designed to help increase yield and reduce reworking times in solar cell manufacturing.

Purification of the process gases utilized in solar cell production has become critical to enhancing yields and conversion efficiency. Pall will feature two new media for its Gaskleen® purifier assemblies. The AresKleen™ HCLP media is highly effective in removing trace moisture down to < 15 parts per billion (ppb) levels from HCl gas used in the formation of trichlorosilane, a key ingredient in the production of polysilicon. Silane, also involved in making polysilicon as well as amorphous silicon PV cells, frequently contains trace siloxane and moisture. AresKleen SIP medium reduces these detrimental contaminants to sub-ppb levels. All Pall purifiers have integrated, highly efficient particle filters.

“The Pall Maxi GasKleen purifier with SIP material was evaluated by CVD Equipment Corporation and was found to lower dopant metal contaminants (As, P, Al and B) in a low grade silane line, resulting in improved silicon-epitaxial layers with impurities in the parts per trillion atomic (ppta) range,” said Karlheinz Strobl, VP of business development, CVD Equipment Corporation. “We, therefore, find the Pall Purifier to be eminently capable of achieving below ppb levels of these contaminants in hydrogen, argon and silane process gases utilized in silane epitaxial film deposition.”

Pall will present its fully automatic Water Reclaim System for recovering over 90% of deionized water used during silicon ingot shaping. The system efficiently and economically removes the resultant silicon fines without the need for chemical additives, providing essentially particle-free water for cost-effective recycling. A major supplier of shaping and grinding tools for the solar industry highly recommends this reclaim system.

Another exhibit will highlight Blowback Filtration Systems for the protection of CZ ingot puller vacuum pumps. A display of innovative filters and uniquely designed housings for chemical and water filtration will round out Pall’s showcase at Intersolar. The systems and products provide long-term service without the interruption of frequent change-outs, increasing uptime and reducing maintenance costs for solar cell producers.

PORT WASHINGTON, N.Y.–(BUSINESS WIRE)– Pall Corporation (NYSE: PLL) today announced that the Company has been contracted by the city of Calexico, California, to deliver four Pall Aria™ mobile water treatment systems supplying a total of up to four million gallons of potable water per day. The Pall systems were implemented following an earthquake that disrupted the city’s water supply.

“Pall is very pleased to provide the city of Calexico with a solution that helps meet its potable water needs during this unfortunate disaster,” said Jeff Seibert, president, Pall Water Processing. “Pall Aria systems in trailers or containers can be deployed immediately in response to emergencies. In the case of Calexico, we mobilized in less than a day and began producing water within hours after arrival.”

“The Pall systems have helped alleviate a very difficult situation,” said Victor Rodriguez, supervisor of Calexico’s water treatment plant. “Our normal production volume was reduced significantly due to the earthquake, and the systems have helped us meet our critical needs until the existing municipal system can be restored to full operation.”

Pall Aria systems require minimal manpower for operation and maintenance. They significantly reduce the use of consumables, such as cleaning chemicals, scale inhibitors, and cartridge filters. The systems housed in trailers or large containers enable municipalities, troop units and ships at sea to boost water production on a permanent or temporary basis.

In October 2009, two Pall Aria mobile water treatment systems were deployed as part of “Operation Padang Assist,” the Australian government’s humanitarian response to earthquakes in Indonesia. Two water sources established by the Australian Department of Defence on the beach of Padang used the Pall systems to convert sea water into potable water for up to 75,000 households.

Pall Aria systems are capable of producing drinking water from almost any raw water source within about an hour. Each system comprises complete, automated and integrated microfiltration systems, and in some cases, reverse osmosis systems as well. Using state-of-the-art hollow fiber membrane technology, the systems transform contaminated water into water that is free from harmful bacteria, cysts, and particles.

“The relief efforts following the earthquakes in both Calexico and Padang illustrate the Pall Aria system’s ability to produce clean water virtually anywhere utilizing any feed source,” Mr. Seibert said.

Pall is a leader in membrane technology solutions for municipal development, industrial water applications, and emergency relief. The Company provides water treatment systems for large and small municipalities and industrial customers around the world. In addition to serving the $6 billion municipal water market, Pall’s filtration technology is increasingly becoming a critical step in treating water for a wide range of applications. This includes intake and process water for food, beverage, chemical, oil, gas, power and semiconductor production, among others. Pall’s technology helps to ensure a greener future by enabling businesses to conserve and reuse water, and to restore wastewater to environmentally safe levels before discharge.
