made them easy for users to operate, monitor and
service.
Built for tough construction and maintenance
applications, Chicago Pneumatic said the CPS 11.0
and CPS 11-12 were well-suited to surface drilling,
abrasive blasting and ice blasting, as well as road
work and shotcrete pumping applications.
It said the 12 bar variant was also suitable for
special applications suchas fibreopticcabling, with
the higher working pressure enabling it to push
cabling through longer pipeline distances without
incurringpressure loss.
Thenew electronic control panel was said tooffer
users an improved interface and straight forward
control and monitoring options, as well as making
it simple for operators to quickly start and stop the

the unit has been running at full load.
The company said the newmodels also featured a
175 l fuel tank which themanufacturer said allowed
them to run non-stop at full load for an entire shift
without refuelling. A fullyautomatic step-less speed
regulator also means the engine speed can be
adapted to air demand.
Supply agreements
Engine manufacturers have also been busy
announcing supply agreements with compressor
producers in the light of the strict new emissions
laws in theUS and Europe.
John Deere Power Systems, for instance, said
its PowerTech Tier 4 Final/Stage IV engines would
power three new air compressors from Atlas Copco
– the XAS 750, XAS 1800 andXATS 1050 JDmodels.
It said the XAS 750 compressor would feature the
PowerTech 187 kW PVS 6.8L engine, while the XAS
1800would be driven by the 393 kW PSS 13.5L
engine, and the new XATS 1050 JDwould be
drivenby the 242 kWPSS 9.0L engine.
Atlas Copco and John Deere have
partnered on air compressor solutions
since the 1990s, when Environmental
Protection Agency (EPA) off-highway diesel
engine emissions regulations were first
introduced. Throughout the transitions
between tiers, John Deere said it had
worked closely with the OEM to select
and integrate engines optimised for the
application.
To meet Final Tier 4/Stage IV
requirements in the 93 kW and above
power range, JohnDeere said it configured
an integrated emissions control system
featuring cooled exhaust gas recirculation

ental companies are generally looking for
robust, reliable equipment when investing
in new compressors, as well as flexibility in
termsof runningmultiple toolsandadaptingengine
speeds to air demands.
The sector’s manufacturers are listening, and are
working hard to constantly refine their designs in
order to better serve the industry. While many of
the latest product updates have been developed in
response to strict newexhaust emissions legislation
in Europe and the US, producers have also focussed
on increasing fuel efficiency, extending service
intervals, reducingmaintenance and reducing noise
pollution.
Kaeser Kompressoren product manager Ralf
Herethhighlighted low-emissionsmachinesasakey
consideration for rental companies.
“Facing an increasing number of municipal
environmental zones and corresponding calls for
tender, it is becomingmore andmore important for
rental companies to offer customers appropriate
state-of-the-art equipment,” he said.
The manufacturer has developed a low-emission
Mobilair product range for engines below 19 kW
(compressor models M20 and M27) and for
engines from 85 kW to 265 kW (M114 to M350
models), the former offering emissions
compliance without a diesel particulate
filter, and the latter using a range of
aftertreatment technologies to comply.
“In the course of 2015, Kaeser will present
further new innovative models and will
extend its low-emission Mobilair product
range down to 36kW engine power,” Mr Hereth
added.
Meanwhile, Chicago Pneumatic has also
launched new emissions-compliant portable
compressors in the form of new versions of its 7
bar CPS 11.0 and 12 bar CPS 11-12 models, boasting
EU Stage IIIB-compliant Deutz engines and a new
electronic control panel which the company said
Jenny Products focussed on improving volumes with its latest
launch – the electric-powered J5A-30P air compressor, which it
claims boasts the highest volume in its class
