INTRODUCTION

4. Traditional rotary screw air compressors, while foundational to numerous
industrial operations, have historically posed several environmental challenges.
This chapter examines the impact of conventional compressor systems on the
environment and highlights the necessity of adopting greener technologies to
mitigate these effects.
Energy Consumption and Emissions:
One of the most significant environmental concerns associated with traditional
air compressors is their high energy consumption. Being one of the largest
energy users in industrial settings, these compressors contribute substantially
totheoverallenergyfootprintofbusinesses,leadingtoincreasedcarbondioxide
(CO2) and other greenhouse gas emissions. The reliance on fossil fuels to
generate the electricity that powers these units further exacerbates their
environmental impact.
Oil Contamination:
Oil-lubricated air compressors, common in many traditional setups, can pose a
riskofoilcontamination.Oilvaporsandaerosolscanescapeintotheatmosphere
or end up contaminating the compressed air supply, leading to potential health
risks for workers and environmental pollution. Additionally, the disposal of used
oil and oil filters must be managed carefully to avoid harming the environment.
Noise Pollution:
The operation of traditional air compressors can also contribute to noise
pollution. Older models, in particular, tend to operate at higher decibel levels,
which can affect the well-being of employees and disturb surrounding
communities, especially in densely populated or quiet areas.
THE ENVIRONMENTAL IMPACT OF TRADITIONAL AIR COMPRESSORS

5. UNDERSTANDING ROTARY SCREW COMPRESSORS
At its core, a rotary screw air compressor is a marvel of engineering designed to
provide continuous, high-quality compressed air. It operates on a simple yet
effective principle: two meshing helical screws,known as rotors, compress air as
it moves through the compressor. This design allows for a steady flow of air,
making it ideal for extensive industrial use where consistent air supply is critical.
The ELGi Advantage
What sets ELGi’s rotary screw air compressors apart is not just our innovative
design but our commitment to pushing the boundaries of what’s possible in air
compressor technology. ELGi focuses on creating compressorsthat are not only
powerful but also efficient and environmentally friendly. Features like variable
speed,two-stagetechnology,andefficientmotorsareespeciallyenergy-saving.
With ELGi’s Air~Alert, customers can also monitor their compressed air system
efficiency 24/7 and prevent breakdowns and failures.
Oil-Free vs. Oil-Lubricated: A Choice for Every Need

AB Series - WATER-INJECTED 11-110KW

6. Oil-lubricated compressors, on the other hand,areknown for their durability and
efficiency, making them suitable for more demanding industrial environments.
Despite involving oil in the compression process, ELGi’s designs ensure a low oil
carryover and thus minimal environmental impact, combining high performance
with eco-friendly operation. Here is the ELGi Series product line making a
difference:
EG SERIES SCREW AIR COMPRESSOR
EQ SERIES SCREW AIR COMPRESSORS 11 – 22 kW
EN SERIES SCREW AIR COMPRESSORS 2.2-37 KW
As the global emphasis on environmental sustainability grows, the air
compressor industry has seen a significant shift towards green technologies.
These innovations aim to reduce the environmental impact of compressed air
systems while enhancing efficiency and reliability. ELGi is at the forefront of this
transition, introducing cutting-edge solutions that redefine what it means to be
both powerfuland eco-friendly.
The Drive for Sustainability:
Sustainability in air compressorsrevolvesaroundreducingenergyconsumption,
minimising emissions, and ensuring compressed air purity. ELGi tackles these
challenges head-on by integrating green technologies into its compressor
