What Is a Screw Compressor Air Filter?
A screw compressor air filter is an important component installed on the compressor's air-inlet system. Its primary function is to remove dust, dirt and airborne contaminants before ambient air enters the compressor element.
In a rotary screw compressor, contaminated inlet air can eventually affect the compression element, lubricant and other internal components. Atlas Copco specifically notes that dust and dirt entering the compressor can cause damage to rotors and housings, reduce performance and potentially contribute to compressor failure.
For this reason, the inlet air filter should not be treated as an ordinary consumable.
It is a protective component for the compressor airend and the entire compressed-air system.
Why Is an Air Filter Important in a Screw Compressor?
A screw compressor continuously draws atmospheric air into the compressor.
That atmospheric air may contain:
Dust
Dirt
Fine particles
Industrial contaminants
Textile fibres
Metal particles
Oil mist
Construction dust
Chemical particles
Other airborne contamination
Without effective filtration, these contaminants can enter the compressor.
A properly selected air filter helps:
1. Protect the Airend
The screw compressor airend contains precision-machined male and female rotors. Contamination can contribute to wear and loss of efficiency.
2. Protect Compressor Lubricant
Contaminated intake air can negatively affect the cleanliness and service life of the compressor's lubrication system.
3. Maintain Compressor Efficiency
A dirty or incorrectly selected filter can increase pressure drop. This means the compressor may need to work harder to achieve the required operating conditions.
Atlas Copco highlights the importance of balancing filtration efficiency, filter lifetime and minimum pressure drop.
4. Reduce Unplanned Downtime
A correctly maintained filtration system reduces the possibility of contamination-related compressor problems.
5. Improve Compressor Component Life
Clean intake air helps protect the airend, lubricant, separator and other internal components. Sullair, for example, states that its OptimalAir inlet filtration is designed to protect the airend, oil filter, lubricant and separator.
Types of Screw Compressor Air Filters
Not every screw compressor uses the same filter design.
Common configurations include:
Cylindrical Air Filter Elements
These are commonly found in industrial compressor inlet systems and may have:
Cylindrical filter media
Metal protective mesh
Rubber or polymer end caps
Central opening
Sealing gasket
The attached product is an example of this general cylindrical industrial filter construction.
Panel-Type Filters
Some compressor packages use flat or panel-style filtration arrangements.
Multi-Stage Inlet Filtration
Some compressors use more than one filtration stage. Kaeser, for example, specifies a two-stage, 1-micron air intake filter on certain ASD models.
Pre-Filter + Main Filter
Certain compressor systems can incorporate a pre-filter or filter grille before the primary filter.
Ingersoll Rand's maintenance kits, for example, can include an air filter element along with a pre-filter pad and, on certain configurations, a filter grille element.
Major Screw Compressor Brands That Use Inlet Air Filters
One important point:
The fact that a compressor series uses an air filter does not mean the pictured filter is automatically compatible with that series.
The correct filter must be matched to the specific machine.
The following major screw-compressor manufacturers have documented inlet-air filtration systems or air-filter elements within their compressor ranges.
Brand Screw Compressor Series / Examples Air Filter Evidence
Atlas Copco GA, G series Air filtration is part of compressor design; model-specific filters are available
ELGi EG Series ELGi offers custom-made filters and separators
Ingersoll Rand R / RS Series OEM maintenance kits include air filter elements
Sullair LS Series OptimalAir inlet air filter
Kaeser ASD and other ranges Air intake filtration specified on ASD models
CompAir L Series Lubricated rotary screw compressor range
BOGE C, S, SF and related ranges Compressor designs incorporate intake filtration
Fusheng SA / SA Plus SA Series incorporates air filters as maintenance components
Quincy QGS / QGSV QGS specifies high-efficiency intake filtration
Gardner Denver ESM / VS Series Lubricated rotary screw compressor range
Atlas Copco Screw Compressor Air Filters
Atlas Copco manufactures a wide range of oil-injected rotary screw compressors under the GA and G families.
Its current GA range covers compressor packages from approximately 5.5 kW to 500 kW, depending on configuration.
Examples include:
GA 5.5–11 kW
GA 11–30
GA 15–30
GA 30–90
GA 37–110 VSD+
GA 90–160
GA 160–315
Larger GA ranges
Atlas Copco also publishes dedicated air-filter products for specific compressor groups. For example, its parts catalogue identifies an air filter complete for GA55+–90.
This proves an important SEO point:
Atlas Copco screw compressors use model-specific air filters; the filter should be matched using the compressor model or part number rather than appearance alone.
ELGi Screw Compressor Air Filters
ELGi is another major compressor manufacturer with a large installed base in India.
The EG Series includes:
EG 11–75 kW
EG 90–160 kW
EG 200–250 kW
ELGi describes these as oil-lubricated screw compressors.
ELGi also specifically states that its compressor parts portfolio includes custom-made filters and separators, designed to protect compressors from dust and dirt.
Therefore, customers looking for an ELGi air filter should provide:
Compressor model
kW/HP
Serial number if available
Existing filter part number
Filter dimensions
Photograph of the old filter
Ingersoll Rand Screw Compressor Air Filters
Ingersoll Rand's R/RS rotary screw compressor ranges use dedicated maintenance filter components.
For example, Ingersoll Rand documentation for R Series compressors in the 11–22 kW / 15–30 HP range lists air filter elements as part of maintenance kits.
Certain maintenance kits also include:
Air filter element
Air-oil separator element
Coolant filter
Pre-filter pad
Filter grille element
depending on the machine configuration.
This is particularly important because two compressors from the same manufacturer can require different filtration components.
Sullair Screw Compressor Air Filters
Sullair's LS Series is another major industrial rotary screw compressor family.
The current LS Series covers approximately:
125–350 HP
90–260 kW
100–200 psi
depending on model and region.
Sullair identifies its OptimalAir® Air Filter as a high-efficiency/heavy-duty inlet filter and states an overall efficiency of 99.9% according to ISO 5011 for the current LS Series information.
Kaeser Screw Compressor Air Filters
Kaeser uses inlet-air filtration systems across its rotary screw compressor ranges.
For example, Kaeser's ASD 25, ASD 30 and ASD 40 documentation specifies a two-stage, 1-micron air intake filter.
Examples include:
ASD 25
ASD 30
ASD 40
ASD 40S
ASD 40T
Other ASD configurations
However, the correct replacement element still has to be identified from the exact machine.
CompAir Screw Compressor Air Filters
CompAir's L Series covers a wide range of lubricated rotary screw compressors.
Examples include:
L07–L11
L15–L22
L23–L29
L45–L55
L90–L132
Other L-Series configurations
CompAir states that the L23–L29 range is available in fixed-speed and regulated-speed versions.
CompAir also warns that externally similar components can differ significantly and that incorrect filters can increase pressure loss and energy requirements.
That makes correct filter identification particularly important.
BOGE Screw Compressor Air Filters
BOGE manufactures several screw-compressor families, including:
C Series
C-2 Series
S Series
S-3 Series
S-4 Series
SF Series
Other configurations
BOGE's C Series covers approximately 4–30 HP, while its wider screw-compressor portfolio extends considerably higher.
Older BOGE C-Series documentation also describes a silenced intake filter with a paper filter cartridge designed to separate particles larger than 3 µm.
Fusheng Screw Compressor Air Filters
Fusheng's SA Series is used across industrial rotary screw compressor applications.
The manufacturer describes SA Series machines ranging from approximately 5.5 kW to 220 kW, depending on model/configuration.
Fusheng specifically identifies the air filter as a maintenance component in its SA Series design.
Examples include models such as:
SA+06
SA08XV
SA+11
SA11XV
SA15XV
SA15C+
SA22XV
SA22C+
The exact replacement filter must be confirmed against the compressor model.
Quincy Screw Compressor Air Filters
Quincy Compressor's QGS rotary screw compressor family covers approximately 5–60 HP.
Examples include:
QGS-5
QGS-7.5
QGS-10
QGS-15
QGS-20
QGS-20S
QGS-25
QGS-30
QGS-40
QGS-50
QGS-60
Quincy specifies a high-efficiency intake filter on the QGS range.
Gardner Denver Screw Compressor Air Filters
Gardner Denver manufactures lubricated rotary screw compressors including its ESM/VS range.
Current product information includes:
ESM/VS 7.5–11 kW
ESM/VS 45–55 kW
Other ESM/VS configurations
The manufacturer describes these as lubricated rotary screw compressors designed for industrial applications.
Again, the air-filter element should be identified by machine specification rather than visual similarity.
How to Identify the Correct Screw Compressor Air Filter
This is where most purchasing mistakes happen.
Do not order an air filter only by saying “I need an Atlas Copco filter” or “I need a screw compressor filter.”
Send the following information.
1. Compressor Brand
Example:
Atlas Copco
2. Compressor Model
Example:
GA 37
3. Compressor Power
Example:
37 kW / approximately 50 HP
4. Part Number
If printed on the old filter, provide it.
5. Filter Dimensions
Measure:
Overall height
Outside diameter
Inside diameter
Top opening
Bottom opening
Gasket diameter
Gasket thickness
6. Photograph
A clear photograph of the complete filter and its end caps is extremely useful.
7. Old Filter vs New Filter
If possible, photograph both side-by-side.
Why Filter Dimensions Matter
Two filters can look almost identical but still be completely different.
For example:
Filter A
300 mm height
150 mm OD
80 mm ID
Filter B
305 mm height
150 mm OD
75 mm ID
Visually they may look almost identical.
But the sealing arrangement can be different.
That small dimensional difference can cause:
Air leakage
Poor filtration
Incorrect installation
Excessive pressure drop
Contamination entering the airend
OEM manufacturers therefore emphasize model-specific filtration rather than generic one-size-fits-all components. Atlas Copco explicitly warns that generic filters can make compromises in specifications and potentially increase pressure drop and energy consumption.
Signs That Your Screw Compressor Air Filter Needs Replacement
Look for the following symptoms:
High Filter Differential Pressure
A clogged filter restricts the compressor's intake airflow.
Increased Power Consumption
A restricted inlet can contribute to higher operating losses.
Reduced Compressor Performance
The compressor may struggle to maintain the expected air delivery.
Dirty or Damaged Filter Media
Visible contamination, deformation or damage is a clear warning.
Excessive Dust Around the Intake
A heavily contaminated operating environment can shorten filter life.
Frequent Compressor Alarms
Some modern compressors monitor filtration and may generate service or differential-pressure warnings.
Abnormal Compressor Loading
Changes in compressor loading behaviour can sometimes indicate an intake restriction, although other causes must also be investigated.
What Happens If You Continue Using a Dirty Air Filter?
A severely contaminated filter can restrict airflow.
That can lead to:
Restricted airflow → higher pressure drop → increased compressor loading → reduced efficiency → higher operating cost
At the same time, if the filter is damaged or improperly sealed:
Unfiltered air → contamination entering compressor → accelerated wear → reduced component life → possible downtime
This is why replacing the air filter is not simply a routine housekeeping activity.
It is part of compressor protection.
How Often Should a Screw Compressor Air Filter Be Replaced?
There is no single replacement interval that applies to every screw compressor.
The correct interval depends on:
Manufacturer
Compressor model
Operating hours
Ambient dust
Factory environment
Temperature
Air quality
Filter design
Differential pressure
Manufacturer maintenance schedule
A compressor operating in a clean environment and one operating in a dusty textile, cement, foundry or construction environment should not automatically be treated identically.
Follow the compressor manufacturer's maintenance recommendation and inspect the filter condition regularly.
OEM vs Compatible Screw Compressor Air Filter
There are two common approaches.
OEM Filter
An OEM filter is designed according to the compressor manufacturer's specifications.
Advantages can include:
Known fitment
Specified filtration characteristics
Correct sealing
Known pressure-drop characteristics
Manufacturer-backed specification
Compatible / Replacement Filter
A properly manufactured compatible filter can be a practical alternative when it matches the required:
Dimensions
Filter media
Filtration efficiency
Airflow
Pressure drop
Temperature resistance
Sealing arrangement
Mechanical construction
But “compatible” should never mean “looks similar.”
The filter needs to be technically matched.

Why Buy the Correct Air Filter Instead of a Generic Filter?
The cheapest filter is not necessarily the cheapest solution.
Suppose a compressor runs:
16 hours/day × 300 days/year = 4, 800 operating hours/year
Even a small efficiency penalty or unnecessary pressure drop can accumulate over thousands of operating hours.
The real cost of a filter should therefore be evaluated using:
Purchase price + pressure-drop cost + maintenance cost + compressor-risk cost
rather than only:
Filter purchase price
This is exactly why compressor manufacturers emphasize proper filter specification and pressure-drop control.
Industries That Need Screw Compressor Air Filters
Screw compressors are widely used in:
Textile industries
Pharmaceutical manufacturing
Automotive plants
Engineering industries
CNC machining
Packaging
Food processing
Electronics
Plastic manufacturing
Printing
Chemical industries

What Is a Screw Compressor Air Filter?
A screw compressor air filter is an important component installed on the compressor's air-inlet system. Its primary function is to remove dust, dirt and airborne contaminants before ambient air enters the compressor element.
In a rotary screw compressor, contaminated inlet air can eventually affect the compression element, lubricant and other internal components. Atlas Copco specifically notes that dust and dirt entering the compressor can cause damage to rotors and housings, reduce performance and potentially contribute to compressor failure.
For this reason, the inlet air filter should not be treated as an ordinary consumable.
It is a protective component for the compressor airend and the entire compressed-air system.
Why Is an Air Filter Important in a Screw Compressor?
A screw compressor continuously draws atmospheric air into the compressor.
That atmospheric air may contain:
Dust
Dirt
Fine particles
Industrial contaminants
Textile fibres
Metal particles
Oil mist
Construction dust
Chemical particles
Other airborne contamination
Without effective filtration, these contaminants can enter the compressor.
A properly selected air filter helps:
1. Protect the Airend
The screw compressor airend contains precision-machined male and female rotors. Contamination can contribute to wear and loss of efficiency.
2. Protect Compressor Lubricant
Contaminated intake air can negatively affect the cleanliness and service life of the compressor's lubrication system.
3. Maintain Compressor Efficiency
A dirty or incorrectly selected filter can increase pressure drop. This means the compressor may need to work harder to achieve the required operating conditions.
Atlas Copco highlights the importance of balancing filtration efficiency, filter lifetime and minimum pressure drop.
4. Reduce Unplanned Downtime
A correctly maintained filtration system reduces the possibility of contamination-related compressor problems.
5. Improve Compressor Component Life
Clean intake air helps protect the airend, lubricant, separator and other internal components. Sullair, for example, states that its OptimalAir inlet filtration is designed to protect the airend, oil filter, lubricant and separator.
Types of Screw Compressor Air Filters
Not every screw compressor uses the same filter design.
Common configurations include:
Cylindrical Air Filter Elements
These are commonly found in industrial compressor inlet systems and may have:
Cylindrical filter media
Metal protective mesh
Rubber or polymer end caps
Central opening
Sealing gasket
The attached product is an example of this general cylindrical industrial filter construction.
Panel-Type Filters
Some compressor packages use flat or panel-style filtration arrangements.
Multi-Stage Inlet Filtration
Some compressors use more than one filtration stage. Kaeser, for example, specifies a two-stage, 1-micron air intake filter on certain ASD models.
Pre-Filter + Main Filter
Certain compressor systems can incorporate a pre-filter or filter grille before the primary filter.
Ingersoll Rand's maintenance kits, for example, can include an air filter element along with a pre-filter pad and, on certain configurations, a filter grille element.
Major Screw Compressor Brands That Use Inlet Air Filters
One important point:
The fact that a compressor series uses an air filter does not mean the pictured filter is automatically compatible with that series.
The correct filter must be matched to the specific machine.
The following major screw-compressor manufacturers have documented inlet-air filtration systems or air-filter elements within their compressor ranges.
Brand Screw Compressor Series / Examples Air Filter Evidence
Atlas Copco GA, G series Air filtration is part of compressor design; model-specific filters are available

Other L-Series configurations
CompAir states that the L23–L29 range is available in fixed-speed and regulated-speed versions.
CompAir also warns that externally similar components can differ significantly and that incorrect filters can increase pressure loss and energy requirements.
That makes correct filter identification particularly important.
BOGE Screw Compressor Air Filters
BOGE manufactures several screw-compressor families, including:
C Series
C-2 Series
S Series
S-3 Series
S-4 Series
SF Series
Other configurations
BOGE's C Series covers approximately 4–30 HP, while its wider screw-compressor portfolio extends considerably higher.
Older BOGE C-Series documentation also describes a silenced intake filter with a paper filter cartridge designed to separate particles larger than 3 µm.
Fusheng Screw Compressor Air Filters
Fusheng's SA Series is used across industrial rotary screw compressor applications.
The manufacturer describes SA Series machines ranging from approximately 5.5 kW to 220 kW, depending on model/configuration.
Fusheng specifically identifies the air filter as a maintenance component in its SA Series design.
Examples include models such as:
SA+06
SA08XV
SA+11
SA11XV
SA15XV
SA15C+

Examples include:
QGS-5
QGS-7.5
QGS-10
QGS-15
QGS-20
QGS-20S
QGS-25
QGS-30
QGS-40
QGS-50
QGS-60
Quincy specifies a high-efficiency intake filter on the QGS range.

Current product information includes:
ESM/VS 7.5–11 kW
ESM/VS 45–55 kW
Other ESM/VS configurations
The manufacturer describes these as lubricated rotary screw compressors designed for industrial applications.
Again, the air-filter element should be identified by machine specification rather than visual similarity.
How to Identify the Correct Screw Compressor Air Filter
This is where most purchasing mistakes happen.
Do not order an air filter only by saying “I need an Atlas Copco filter” or “I need a screw compressor filter.”
Send the following information.
1. Compressor Brand
Example:
Atlas Copco
2. Compressor Model
Example:
GA 37
3. Compressor Power
Example:
37 kW / approximately 50 HP
4. Part Number
If printed on the old filter, provide it.
5. Filter Dimensions
Measure:
Overall height
Outside diameter
Inside diameter
Top opening
Bottom opening
Gasket diameter
Gasket thickness
6. Photograph
A clear photograph of the complete filter and its end caps is extremely useful.
7. Old Filter vs New Filter
If possible, photograph both side-by-side.
Why Filter Dimensions Matter
Two filters can look almost identical but still be completely different.
For example:
Filter A
300 mm height
150 mm OD
80 mm ID
Filter B
305 mm height
150 mm OD
75 mm ID
Visually they may look almost identical.
But the sealing arrangement can be different.
That small dimensional difference can cause:
Air leakage
Poor filtration
Incorrect installation
Excessive pressure drop
Contamination entering the airend
OEM manufacturers therefore emphasize model-specific filtration rather than generic one-size-fits-all components. Atlas Copco explicitly warns that generic filters can make compromises in specifications and potentially increase pressure drop and energy consumption.

There is no single replacement interval that applies to every screw compressor.
The correct interval depends on:
Manufacturer
Compressor model
Operating hours
Ambient dust
Factory environment
Temperature
Air quality
Filter design
Differential pressure
Manufacturer maintenance schedule
A compressor operating in a clean environment and one operating in a dusty textile, cement, foundry or construction environment should not automatically be treated identically.
Follow the compressor manufacturer's maintenance recommendation and inspect the filter condition regularly.
OEM vs Compatible Screw Compressor Air Filter
There are two common approaches.
OEM Filter
An OEM filter is designed according to the compressor manufacturer's specifications.
Advantages can include:
Known fitment
Specified filtration characteristics
Correct sealing
Known pressure-drop characteristics
Manufacturer-backed specification
Compatible / Replacement Filter
A properly manufactured compatible filter can be a practical alternative when it matches the required:
Dimensions
Filter media
Filtration efficiency
Airflow
Pressure drop
Temperature resistance
Sealing arrangement
Mechanical construction
But “compatible” should never mean “looks similar.”
The filter needs to be technically matched.

Why Buy the Correct Air Filter Instead of a Generic Filter?
The cheapest filter is not necessarily the cheapest solution.
Suppose a compressor runs:
16 hours/day × 300 days/year = 4, 800 operating hours/year
Even a small efficiency penalty or unnecessary pressure drop can accumulate over thousands of operating hours.
The real cost of a filter should therefore be evaluated using:
Purchase price + pressure-drop cost + maintenance cost + compressor-risk cost
rather than only:
Filter purchase price
This is exactly why compressor manufacturers emphasize proper filter specification and pressure-drop control.

Frequently Asked Questions
1. What is a screw compressor air filter?
A screw compressor air filter is an inlet filtration component that removes airborne contaminants from the air before it enters the compressor's compression element.
2. Why is an air filter important in a rotary screw compressor?
It protects the compressor from dust and other airborne contamination and helps maintain proper compressor performance and component life.
3. Does every screw compressor use the same air filter?
No. Air filters vary according to compressor brand, model, airend, airflow requirement, dimensions and filter design.
4. Can one air filter fit multiple screw compressor models?
Yes, in some cases the same filter specification may be used across multiple models, but this must be confirmed through a part-number or dimensional cross-reference.
5. Can I identify the air filter only from a photograph?
A photograph can help identify the filter, but it should ideally be combined with the compressor model, part number and dimensions.
6. What brands of screw compressor air filters are available from MK Compressor?
MK Compressor handles multi-brand compressor spare-part enquiries including Atlas Copco, ELGi, Ingersoll Rand, Sullair and other brands, subject to model and availability.
7. Is the filter in the attached image suitable for every screw compressor?
No. The image shows the general cylindrical filter construction, but exact compatibility cannot be established from appearance alone.
8. How do I order the correct screw compressor air filter?
Send the compressor brand, model, kW/HP, existing filter part number and clear photographs. If the part number is unavailable, provide accurate filter dimensions.
9. What are the signs of a clogged air filter?
Common signs can include increased inlet restriction, reduced performance, higher pressure drop, service alerts and potentially increased energy consumption.
10. Can a compatible air filter be used instead of an OEM filter?
Yes, provided the replacement filter is technically equivalent for the specific compressor application. Compatibility should be based on specifications, not simply physical appearance.
11. How often should I replace my screw compressor air filter?
The interval depends on the compressor manufacturer's maintenance schedule and the operating environment. Dusty industrial environments may require more frequent inspection or replacement.
12. Can MK Compressor help identify an unknown compressor filter?
Yes. Providing the compressor brand, model, part number or clear photographs helps MK Compressor evaluate the correct spare part requirement.
13. Does MK Compressor supply air compressor spare parts in Ahmedabad?
Yes. MK Compressor is based in Ahmedabad and lists air filters and other compressor spare parts among its product categories.
14. Do Atlas Copco, ELGi, Sullair and Ingersoll Rand use different filters?
They have their own model-specific filtration specifications and parts. Therefore, the correct replacement should be selected according to the exact compressor model and part number rather than brand name alone.
15. What information should I send to get a filter quotation?
Send:
Brand + Model + HP/kW + Part Number + Filter Photo + Dimensions
For example:
Atlas Copco GA 37 VSD – 37 kW – Air Filter – Photo Attached
This gives the supplier enough information to check the correct application.
