are vital in industries like pharmaceuticals.
CLEAN COMPRESSED AIR FOR SENSITIVE ENVIRONMENTS
UNDERSTANDING OIL-FREE SCREW AIR COMPRESSORS
Why Clean Compressed Air Matters
The repercussions of compressed air contamination in sensitive environments
are profound. Contaminants such as oil, dust, bacteria, liquid water, aerosol, and
dry particulates can lead to:
Lower product quality
Increased product recalls
Unnecessary downtime
Equipment damage
Compliance violations
In sensitive environments, clean compressed air isn't just an advantage; it's a
necessity. This chapter emphasises the importance of clean compressed air and
introduces the critical role that oil-free compressors play in these environments.
Oil-freescrewcompressors,aspecialisedtypeofrotaryscrewcompressors,are
distinguished by their capacity to provide high-quality, oil-free compressed air,
rendering them indispensable in compressed air-purity critical industries.
Designed to mitigate the perils of oil contamination, they strictly adhere to
compressed air quality standards, guaranteeing the production of oil-free,
contaminant-free compressed air.
Oil-free screw air compressors consist of several key components that work
together to efficiently compress air without the use of oil in the compression
chamber. The core structure and principles of operation include:
Rotors: At the heart of an oil-free screw compressor are two rotors, often
referred to as helical screws. These rotors are precision-engineered and
designed with a specific helical shape that rotates in opposite directions within a
closed chamber to compress the incoming air.
Air Intake: Ambient air, containing various contaminants and impurities, enters
the compressor through an intake filter. The filter helps remove larger particles
and prevents them from entering the compression chamber.
Compression: As the rotors rotate, they draw in and compress the incoming air.
Thehelicaldesignoftherotorseffectivelytrapsandsqueezestheair,reducingits
volume and increasing its pressure.
Cooling: During compression, the air can become hot. Oil-free screw
compressors typically use air or water cooling systems to maintain the desired
operating temperature and prevent overheating.
Oil-Free Operation: One of the distinguishing features of these compressors is
their oil-free operation. Unlike oil-injected compressors, there is no oil injected
into the compression chamber to seal, cool, or lubricate the rotors. Instead, they
rely on a combination of tight tolerances and advanced materials to operate
without the need for oil or they use water-injection in place of oil-injection.
Discharge: The compressed air at the desired pressure is then discharged and
madeavailableforvariousapplications.Thishigh-quality,oil-freecompressedair
is ideal for use in sensitive environments and industries with stringent
compressed air quality standards.
Selecting the right air compressor is a crucial decision for any industry. It's not a
one-size-fits-all choice; your selection should align with your plant's specific
requirements. In sensitive environments, choosing an oil-free screw compressor
is often the wisest decision to ensure clean, contaminant-free compressed air.
Factors you should consider when choosing an oil-free compressor
Compressed Air Quality Standards: Understanding the compressed air
quality standards required for your industry.
Air Demand: Determining your plant's air demand and flow rate.
Environmental Impact: Evaluating the compressor's impact on the
environment.
Maintenance Needs: Assessing the maintenance requirements.
Energy Efficiency: Considering the compressor's energy efficiency.
Right Size: Properly sizing your compressor ensures optimal performance
and cost-effectiveness.
Additional Factors to consider
When choosing an oil-free screw air compressor, several other factors come into
play. These factors are crucial for maximising the benefits of oil-free technology:
Compact Design: The compact design of oil-free air compressors allows for
space-efficient installation. In environments where space is at a premium, these
compressors offer a practical solution, allowing you to maximise your
workspace.
CHOOSING AN OIL-FREE SCREW AIR COMPRESSOR
Low Maintenance Costs: Compared to oil-lubricated compressors, oil-free air
compressors typically have lower maintenance costs. This means fewer
expenses on maintenance, repairs, and replacement parts, contributing to
overall cost savings.
Lowest Ownership Cost: While the initial investment in an oil-free air compressor
may be slightly higher, the total ownership cost over the compressor's lifetime is
lower. With energy savings, reduced maintenance costs, and longer-lasting
components, the total cost of ownership is one of the most compelling reasons
to choose oil-free air compressors for your industrial needs.
ELGi AB Series oil-free screw air compressors are specially designed to meet all
these factors that will benefit you and your business to soar.
Oil-free screw air compressors are well-suited for applications that demand the
highest compressed air purity standards and where any level of oil
contamination can have serious consequences. Let us now understand the
advantages of oil-free compressors.
Eliminating the Risk of Contamination: Contamination risks in manufacturing can
lead to lower product quality, increased recalls, and downtime. Oil-free air
compressors prevent oil from entering the compressed air, ensuring peace of
mind for manufacturers, protecting their brand, and reducing maintenance
costs. Oil-lubricated compressors introduce trace amounts of oil, leading to
higher maintenance and replacement expenses. Transitioning to oil-free
compressors minimises these risks and reduces maintenance costs
ADVANTAGES OF OIL-FREE COMPRESSED AIR
Reducing Environmental Impact: Oil-flooded compressors need frequent oil
changes, every 6-12 months, leading to significant oil consumption. Disposing of
this oil requires adherence to environmental guidelines. In contrast, oil-free
compressors don't use oil for compression and need oil changes only every 2-3
years, promoting sustainable manufacturing. Oil-free compressors produce
condensate that can be easily discarded or recycled within the plant, reducing
the environmental impact.
Lowering Maintenance Costs: Switching to oil-free screw air compressors
reduces maintenance requirements. Benefits include fewer components to
maintain, longer intervals between oil changes, no need for costly oil filters,
elimination of oily condensate management, longer desiccant life for
downstream air dryers, and reduced labour and outage costs.
Decreasing Energy Costs: Energy costs represent a substantial portion of air
compressor life-cycle expenses, typically 75%(Source: ScienceDirect).
Oil-flooded compressors have multiple oil filters and separators causing
pressure drops, lower air pressure delivery, and increased energy use. Oil-free
compressors operate efficiently, delivering high-pressure compressed air,
resulting in energy savings and significant cost reductions.
With multiple utilisation to fulfill the demand for clean compressed air, let us now
explore how oil-free air compressors can benefit different industries.

Designed to mitigate the perils of oil contamination, they strictly adhere to compressed air quality standards, guaranteeing the production of oil-free, contaminant-free compressed air. Oil-free screw air compressors consist of several key components that work together to efficiently compress air without the use of oil in the compression chamber. The core structure and principles of operation include:
  • 6. Rotors: At the heart of an oil-free screw compressor are two rotors, often referred to as helical screws. These rotors are precision-engineered and designed with a specific helical shape that rotates in opposite directions within a closed chamber to compress the incoming air. Air Intake: Ambient air, containing various contaminants and impurities, enters the compressor through an intake filter. The filter helps remove larger particles and prevents them from entering the compression chamber. Compression: As the rotors rotate, they draw in and compress the incoming air.

Oil-free screw compressors typically use air or water cooling systems to maintain the desired operating temperature and prevent overheating. Oil-Free Operation: One of the distinguishing features of these compressors is their oil-free operation. Unlike oil-injected compressors, there is no oil injected into the compression chamber to seal, cool, or lubricate the rotors. Instead, they rely on a combination of tight tolerances and advanced materials to operate without the need for oil or they use water-injection in place of oil-injection. Discharge: The compressed air at the desired pressure is then discharged and madeavailableforvariousapplications.Thishigh-quality,oil-freecompressedair is ideal for use in sensitive environments and industries with stringent compressed air quality standards.

  • 8. Low Maintenance Costs: Compared to oil-lubricated compressors, oil-free air compressors typically have lower maintenance costs. This means fewer expenses on maintenance, repairs, and replacement parts, contributing to overall cost savings. Lowest Ownership Cost: While the initial investment in an oil-free air compressor may be slightly higher, the total ownership cost over the compressor's lifetime is lower. With energy savings, reduced maintenance costs, and longer-lasting components, the total cost of ownership is one of the most compelling reasons to choose oil-free air compressors for your industrial needs. ELGi AB Series oil-free screw air compressors are specially designed to meet all these factors that will benefit you and your business to soar. Oil-free screw air compressors are well-suited for applications that demand the highest compressed air purity standards and where any level of oil contamination can have serious consequences. Let us now understand the advantages of oil-free compressors. Eliminating the Risk of Contamination: Contamination risks in manufacturing can lead to lower product quality, increased recalls, and downtime. Oil-free air compressors prevent oil from entering the compressed air, ensuring peace of mind for manufacturers, protecting their brand, and reducing maintenance costs. Oil-lubricated compressors introduce trace amounts of oil, leading to higher maintenance and replacement expenses. Transitioning to oil-free compressors minimises these risks and reduces maintenance costs ADVANTAGES OF OIL-FREE COMPRESSED AIR
  • 9. Reducing Environmental Impact: Oil-flooded compressors need frequent oil changes, every 6-12 months, leading to significant oil consumption. Disposing of this oil requires adherence to environmental guidelines. In contrast, oil-free compressors don't use oil for compression and need oil changes only every 2-3 years, promoting sustainable manufacturing. Oil-free compressors produce condensate that can be easily discarded or recycled within the plant, reducing the environmental impact. Lowering Maintenance Costs: Switching to oil-free screw air compressors reduces maintenance requirements. Benefits include fewer components to maintain, longer intervals between oil changes, no need for costly oil filters, elimination of oily condensate management, longer desiccant life for downstream air dryers, and reduced labour and outage costs. Decreasing Energy Costs: Energy costs represent a substantial portion of air compressor life-cycle expenses, typically 75%(Source: ScienceDirect). Oil-flooded compressors have multiple oil filters and separators causing pressure drops, lower air pressure delivery, and increased energy use. Oil-free compressors operate efficiently, delivering high-pressure compressed air, resulting in energy savings and significant cost reductions.
