G 90-355 (VSD)
up to 10 bar(e) / 145 psig

1. Smaller footprints
• Smaller footprint than all competitors.
• Save more installation space, increase capacity in limited
installation space.

2. State-of-the-art screw element
• Atlas Copco designed and patented asymmetric element profile
with high quality bearings offering low wear and increased
reliability.
• The unique profile design provides industry leading energy
efficiency to lower your operating cost.

3. High-efficiency cooler
• Element outlet temperature is optimized, avoid machine shut
down due to element high temperature, increase reliability.
• Stainless cooler bundle avoid corrosion for water cooled
machine.
• Optimized design reduces maintenance cost and increases
reliability.

4. Superior air-oil separation
• Reduction of pressure drops and energy costs.
• Low oil consumption ensures minimal maintenance costs and
long compressor lifetime.
• Optimized design of vessel to reduce the oil carry over, increase
reliability.

5. High-efficiency motor
• High-efficiency (IE3) motor (Class F insulation) adapted to
harshest conditions.
• Long-term stable operation even in harsh environments.

6. Optimal control with the Elektronikon®
MK5 & SmartLink
• Clear icons and intuitive navigation provide you with fast access to
all of the important settings and data.
• Monitoring of the equipment running conditions and maintenance
status..
• SmartLink provides remote monitoring of compressor running
status.

Over 70% of a compressor’s life cycle cost is taken up by the energy it consumes. Moreover, the generation
of compressed air can account for more than 40% of a plant’s total electricity bill. Atlas Copco was the
first compressor manufacturer to introduce compressors with integrated Variable Speed Drive (VSD). With
over 20 years of design and manufacturing experience our VSD technology has reached new heights of
energy savings and reliability. VSD technology reduces energy consumption in systems that have varying
air demand patterns.This reduction in energy consumption not only reduces your energy consumption but
also your carbon footprint to help protect the environment for generations to come.
Why VSD technology?
In almost every production environment, air demand fluctuates depending on different factors (time of the day, week or even month).
Extensive measurements and studies of compressed air demand profiles show that many compressors have substantial variations in
air demand. Only 8% of all installations have a more stable air demand.Tests prove that, even in this case, VSD compressors
save energy.
Profile 1
• 64% of all installations.
• Factory working 24 hrs/day: low
demand at night & high demand
during the day.

Profile 2.
• 28% of all installations.
• Factory working 2 shifts/day,
no weekend work: erratically
varying air demand.

Profile 3.
• 8% of all installations.
• Factory working 2 shifts/day,
no weekend work: typical ‘fixed’
speed application.
