Atlas Copco Extends its Leadership in Oil-Free Air With New ISO 'Class 0' Certificates

    ANTWERP, Belgium, Sept. 3 /CNW/ - Atlas Copco has yet again proven its
world leadership in air-compressor manufacturing - with new ISO 8573-1 CLASS 0
certificates for oil-free air compressors in the centrifugal, tooth, scroll
and water-injected screw ranges. The 'Class 0' rating for these compressors is
the next step in a continuous drive in innovation that began with the
certification of the Z screw compressor range in 2006, the first compressors
in the world to be TUV certified ISO 8573-1 CLASS 0.
    With these latest 'Class 0' certificates, Atlas Copco can offer its
customers a wide range of optimal and efficient compressor solutions capable
of meeting every compressed-air application where high air purity is critical.
    Testing of Atlas Copco oil-free compressors was carried out by the
renowned independent Technische Uberwachungs-Verein (Technical Monitoring
Association, or 'TUV'), using the most stringent test methods available and
simulating realistic industrial environments. Even with such rigorous testing,
the TUV found no traces of oil in the output air stream under any of the test
    "The fact that we can now offer a wide range of Class 0 certified
compressors means that we can help customers select the best and most
efficient compressor technology to improve their productivity and
profitability," says Ronnie Leten, Atlas Copco's Business Area President
Compressor Technique. "It's a strategic choice of Atlas Copco to invest in new
technologies, as this is the best way to help our customers meet their own
targets. And one of the driving forces in Atlas Copco is our commitment to
customer value."

    Importance of 100% oil-free air

    Applications where 100% oil-free air is important include food and
beverage processing, pharmaceutical manufacturing and packaging, chemical and
petrochemical processing, semiconductor and electronics manufacturing, the
medical sector, automotive paint spraying, textile manufacturing and many
    Contamination by even the smallest quantities of oil in such
purity-critical compressed-air applications can result in damaged products or
product batches, high rejection rates and returns, and costly production
downtime and cleanup. Atlas Copco's Class 0 air compressors eliminate the
risks of oil contamination as well as the resulting extra costs, by preventing
oil from entering the production process.
    For Atlas Copco's customers, Class 0 certification means zero risk of
contamination, zero risk of damaged or unsafe products, and zero risk of
losses from operational downtime. Above all, zero risk of ruining a company's
hard-won professional reputation.

    Ranges receiving Class 0 certification

    The Class Zero certification of the Z screw compressors is now extended
with a wide range of oil-free air technologies, including the high-capacity ZH
centrifugal compressors, the ZR/ZT tooth compressors, the AQ water-injected
screw compressors, the SF scroll compressors and the P series of rental
    The ZR/ZT screw compressor range, which was the first in the world to
receive Class 0 certification, is generally the most efficient and reliable
technology for critical applications between 55 and 900 kW.
    With the ZH centrifugal compressor range, Atlas Copco is now able to
offer efficient and certified 100% oil-free air for higher capacity base-load
applications such as the fermentation, air separation and aeration processes
that are important in chemical and pharmaceutical processing. Semiconductor
and other electronics manufacturing, textile production and automotive
applications can now also rely on 100% oil-free air in this capacity class.
    Tooth compressor technology is proven to be the most energy-efficient for
applications up to 50 kW. Here, Atlas Copco's ZR/ZT tooth compressors are
especially essential in food and beverage facilities, pharmaceutical
production and electronics.
    Within the water-injected AQ series, now also Class 0 certified, Atlas
Copco offers an oil-free air compressor which achieves 13 bar. The
water-injected screw technology has proven to be of significant use for
applications such as cosmetics manufacturing, tobacco industry and automotive
    Atlas Copco's SF scroll compressor range delivers pure air for hospital,
dental and medical applications, printing industry, laboratories and dairy
industry processing. These compressors benefit from extremely low noise and
offer high energy efficiency to customers.
    The PT, PTS and PNS rental oil-free portable compressors have recently
also received Class 0 certification, answering industry needs for oil-free air
in applications that are short-term yet purity-critical.
    So whether a company's activities lie in pharmaceutical production, food
processing, critical electronics or other similarly exacting sectors, Atlas
Copco has an oil-free air compressor that can deliver the highest levels of
100% oil-free air - certified - giving customers the ultimate peace of mind.
