CRAWLEY, England -- May 21, 2013

Edwards Group Limited (NASDAQ: EVAC), a leading manufacturer of sophisticated
vacuum products and abatement systems and a leading provider of related
value-added services, will be supplying 35 new XDS dry scroll pumps to CERN,
the European Organization for Nuclear Research, based on the Franco-Swiss
border near Geneva.

CERN has placed an order for 30 XDS35i dry scroll pumps and 5 XDS10 dry scroll
pumps. Some of these pumps are to replace an existing installation of previous
generation Edwards’ scroll pumps; this upgrade to the newer generation of
scroll pumps will take place during CERN’s scheduled extended shutdown,
(2013-2014). CERN’s Linear Accelerator 4 (Linac 4) test bench already has the
new XDS pumps installed. Linac 4 is 80 metres long and located 12 metres below
ground; construction is almost complete, and beams will begin to be produced
in 2014. The full connection to the LHC injector chain is expected in 2017.
This will double the LHC beam brightness, and is the first step in the project
to increase the luminosity of the Large Hadron Collider during the next
decade.

Edwards’ XDS range incorporates a unique dry pumping scroll mechanism that
provides a robust and clean pumping solution. The XDS offer a completely oil
free vacuum and are hermetically sealed; bearing life is significantly
extended, therefore reducing maintenance and environmental impact. Annual
interventions (repairs, labour and maintenance) for Edwards’ XDS10 and XDS35i
dry pumps are on average three times less than that for oil-sealed pumps.
Minor service requirements can be carried out in-situ, an important benefit
for CERN as their pumps have to be serviced on site. The high reliability of
the XDS pumps was another advantage for CERN.

“We have a long experience with scroll pumps produced by Edwards; their
reliability is in line with our expectation” said Paolo Chiggiato, deputy
leader of the Vacuum, Surfaces and Coatings group at CERN.

“Edwards strives to supply leading edge products for leading edge research and
we are delighted that CERN has chosen to use Edwards’ scroll technology for
their highest profile experiments,” commented Russell Coleman, Edwards’ Market
Sector Manager, R&D.

Edwards are at the forefront of vacuum technology for R&D and lab
applications;the comprehensive range of pumping technologies provides
exceptional performance and high reliability.
