Pressure
Pressure at the tool is what matters
A nominal compressor discharge pressure can be consumed by dryer, filter and piping losses. Select from the lowest acceptable point-of-use pressure backwards.

The actual system problem
Small compressed-air demand can still create a big utility problem.
A compressor that fits the horsepower range is not automatically the right air system. Pressure, demand pattern, moisture, receiver storage, treatment and distribution all shape whether production gets stable usable air.
Moisture
Moisture follows compressed air
Cooling compressed air condenses water. The integrated refrigerated dryer is there to control moisture before it reaches tools, machinery and the distribution system.
Demand
Peak demand needs context
A short high-flow event can be handled differently from continuous demand. Receiver storage, acceptable pressure swing and actual consumption profile belong in the sizing decision.
Integration
Scattered components add installation work
Separate compressor, dryer and receiver packages can make a small installation more complicated. AIRCENTER consolidates the essential package components into one station.
Application fit
Built for compact industrial air systems—not for every plant demand.
AIRCENTER SX is strongest where compressed-air demand sits inside the SX range and the customer values an integrated compressor, dryer and receiver. The final selection should still reflect the actual demand profile, pressure requirement, air quality and redundancy expectations.
Strong fit
Smaller industrial operations
A compact footprint and integrated treatment/storage make the SX AIRCENTER a natural fit for shops and smaller production environments with modest continuous demand.
Strong fit
Point-of-use or decentralized stations
The package can support a localized compressed-air requirement where running an oversized central system or long distribution path is undesirable.
Strong fit
Dry-air equipment support
The integrated refrigerated dryer is useful where moisture reduction is important for pneumatic equipment, machinery and general plant-air reliability.
Qualify another route
Large plant baseload
If measured demand exceeds the SX operating envelope, size the compressed-air system from the actual plant requirement rather than forcing the load into an undersized package.
Qualify another route
Strongly variable demand
Where demand swings widely across the shift, document minimum, average and peak consumption before selecting the SX package and its control strategy.
System-level decision
Critical redundancy
If losing one compressor stops production, include redundancy and storage in the system architecture. A single compact package should not be treated as automatic N+1 coverage.
Select from demand backwards
Do not choose the AIRCENTER SX from horsepower alone.
The SX series spans multiple pressure and capacity combinations. The right model is the one that meets the real air requirement after pressure losses, treatment, duty cycle and storage are understood.
Measure demand
Establish average, peak and minimum compressed-air consumption and how long each condition lasts.
Set point-of-use pressure
Start with the lowest pressure the process actually needs, then account for downstream pressure losses.
Define air quality
Confirm whether refrigerated-dryer air is sufficient or whether the process needs additional filtration or a lower pressure dew point.
Size storage and duty
Use receiver volume, acceptable pressure swing and demand spikes to understand cycling and usable stored air.
Choose model and pressure version
Select the SX 3, 4, 5 or 7.5 only after the required complete-system flow at the selected pressure is known.
Product architecture
Compression, drying and storage in one coordinated package.
The SX package combines the screw compressor, refrigerated dryer and receiver as one coordinated compressed-air station rather than three unrelated components.
Compression
SX rotary screw compressor
The package uses a KAESER rotary screw airend with SIGMA PROFILE rotors, driven by a Premium Efficiency IE3 motor.
Drying
Integrated refrigerated dryer
The dryer uses an electronically controlled condensate drain and cycling shutdown logic tied to compressor status, with continuous operation selectable on site.
Storage
52.8-gallon receiver
Every AIRCENTER SX model listed here uses a 52.8-gallon integrated air receiver.
Control
SIGMA CONTROL 2
SIGMA CONTROL 2 provides automatic monitoring/control, Ethernet connectivity, data logging and optional communications modules.
Technical data
AIRCENTER SX pressure and flow stay tied together.
Flow is shown as complete-system flow at each working pressure in acfm so model selection stays tied to the actual pressure requirement.
| Model | Working pressure | Complete-system flow | Motor | Dryer | Receiver | Dimensions W×D×H | Connection | Sound | Weight |
|---|---|---|---|---|---|---|---|---|---|
| AIRCENTER SX 3 | 125 / 160 psi | 12 / 9 acfm | 3 hp | ABT 4 | 52.8 gal | 23 × 43 × 62 in | ¾ NPT | 61 dB(A) | 628 lb |
| AIRCENTER SX 4 | 125 / 160 / 217 psi | 16 / 13 / 9 acfm | 4 hp | ABT 4 | 52.8 gal | 23 × 43 × 62 in | ¾ NPT | 62 dB(A) | 628 lb |
| AIRCENTER SX 5 | 125 / 160 / 217 psi | 21 / 17 / 13 acfm | 5 hp | ABT 8 | 52.8 gal | 23 × 43 × 62 in | ¾ NPT | 63 dB(A) | 639 lb |
| AIRCENTER SX 7.5 | 125 / 160 / 217 psi | 28 / 24 / 19 acfm | 7.5 hp | ABT 4 | 52.8 gal | 23 × 43 × 62 in | ¾ NPT | 66 dB(A) | 661 lb |
Dryer data: ABT 4 and ABT 8 are listed at a 37 °F pressure dew point and use R-513A refrigerant. Electrical supply, exact installed input power, site protection, ventilation and final option content are defined in the selected proposal and installation documentation.
Efficiency strategy
Efficiency starts with the right pressure and the right size.
The SX package includes KAESER’s SIGMA PROFILE airend and demand-oriented control, but the system-level result still depends on selecting the correct pressure version, controlling pressure drop and avoiding unnecessary capacity.
Compression efficiency
SIGMA PROFILE airend
SIGMA PROFILE rotors are specified as an airend-efficiency feature. Actual facility energy performance still depends on pressure, demand, operating hours and the complete compressed-air system.
Thermal management
Dual-flow cooling
Separate air paths support motor, cooler and control-cabinet cooling while helping keep the package thermally stable and serviceable.
Treatment energy
Cycling refrigerated dryer
The integrated dryer can shut down when the compressor is inactive instead of running continuously by default, reducing unnecessary dryer operation.
System pressure
Pressure discipline
Do not select 160 or 217 psi simply because the version exists. Higher-than-required system pressure increases energy use and can amplify artificial demand.
Sizing
Demand-based sizing
A correctly sized fixed-speed package can be very effective on stable smaller loads. Highly variable demand deserves a comparison against alternative control architectures.
Distribution
Pressure-drop control
Dryer, filters, receiver connection and distribution piping all contribute to the pressure seen at the point of use. Keep the full path in the design.
SIGMA CONTROL 2
Machine control is part of the air-system architecture.
SIGMA CONTROL 2 provides monitoring, multiple control modes, Ethernet connectivity and options for broader plant communication.
Interface
Operational visibility
Traffic-light LEDs and an easy-to-read display provide at-a-glance operating status.
Control modes
Automatic monitoring and control
Dual, Quadro, Vario and Continuous control modes are available on the SX control platform.
Data
Data and updates
An SD card slot supports data logging and updates, while the integrated web server supports browser-based access within the configured network environment.
Connectivity
Plant communication
Ethernet is standard, with optional Profibus DP, Modbus, Profinet and DeviceNet modules for plant communication. Final protocol scope belongs in the selected controls package.
Air quality and moisture control
A refrigerated dryer controls water—but it does not define every air-quality requirement.
The integrated ABT dryer operates at a 37 °F pressure dew point. That addresses moisture for many industrial plant-air duties, while particle, oil aerosol, oil vapour or lower-dew-point requirements may call for additional treatment.
Water
Moisture
Use the 37 °F pressure-dew-point rating as the dryer performance reference, then check the application’s actual moisture sensitivity.
Particles
Particles
If downstream equipment or finished product has a particulate requirement, qualify filtration separately rather than assuming the dryer solves it.
Oil control
Oil aerosol and vapour
The SX is a fluid-injected rotary screw compressor. If the process has a defined oil-content requirement, specify the treatment train and required ISO 8573-1 result.
Drainage
Condensate
The dryer uses an electronically controlled condensate drain. Site condensate collection and disposal still belong in the installation plan.
Dew point
Cold environments
Refrigerated-dryer air at approximately 37 °F PDP is not the same as desiccant-dryer air. Outdoor or very cold downstream piping may require another drying strategy.
Qualification
Process acceptance
For finishing, food, instrumentation or other sensitive applications, define the required air quality from the process backwards and validate the complete treatment arrangement.
Ownership playbook
Compact only helps when service remains accessible.
The SX package uses a removable left cover, accessible service points, a durable enclosure and integrated monitoring. Build the room around those service requirements instead of trapping the package against permanent obstructions.
Access
Keep service access real
Preserve access to the removable service side and do not use the compact footprint as permission to eliminate maintenance clearance.
Cooling
Protect cooling airflow
Ventilation and cooling-air routing are part of compressor reliability. Final room and ducting requirements come from KAESER installation documentation.
Condensate
Manage condensate intentionally
Route compressor/dryer condensate into an approved treatment/disposal system rather than treating it as incidental drainage.
Monitoring
Use operating data
Controller status, alarms and maintenance information should be part of the site’s normal ownership routine, not only checked after a production interruption.
System integration sequence
Measure. Select. Engineer. Commission. Sustain.
AIRCENTER SX is a compact package, but the right compressed-air system still starts with the application and ends with verified point-of-use performance.
Measure
Document current demand, pressure, operating hours, production peaks and critical air users.
Select
Choose the model and pressure version from required usable flow, not from the old compressor’s horsepower.
Engineer
Close electrical service, ventilation, condensate, treatment, piping, storage and service-clearance details.
Commission
Verify operating pressure, dryer performance, cycling behaviour, alarms and downstream pressure at representative demand.
Sustain
Track maintenance, pressure, air quality and demand changes so the air station remains matched to production.
Deployment configurations
Use the package where integration creates a real system advantage.
The same AIRCENTER SX can play different roles depending on plant layout and production risk. The model choice and controls strategy should reflect that role.
Single station
Primary small-shop air station
One integrated package supplies the facility when measured demand and redundancy expectations fit the SX capacity range.
Decentralized
Decentralized production cell
Place a dedicated package near a distant or specialized production area to reduce long distribution runs and isolate local demand.
Supplemental
Supplemental capacity
Use as a deliberately engineered supplemental source where system controls, storage and pressure settings prevent compressors from fighting one another.
Redundancy
Duty / standby pair
For critical operations, a second properly integrated unit can provide redundancy, but sequencing and maintenance isolation must be engineered.
Air treatment
Additional filtration package
Additional filtration can be configured around the required contaminant class and downstream process.
Plant control
System-managed station
Where multiple compressors are present, coordinate sequencing and pressure bands so the compressors operate as one system rather than competing with one another.
Business-case framework
Price the air system—not only the compressor.
For a compact package, installation simplicity can matter as much as machine price. Build the comparison around energy, piping, drying, receiver storage, maintenance, downtime exposure and the cost of pressure or air-quality problems.
Capital
Installed scope
Compare the AIRCENTER against the real cost of a separate compressor, dryer, receiver, drains, interconnecting piping and controls.
Energy
Operating energy
Use actual operating hours and demand profile. Do not assign a generic annual savings percentage to the package.
Pressure
Pressure cost
Estimate the effect of unnecessary pressure and pressure drop using the facility’s actual demand and control strategy.
Risk
Downtime exposure
Include the production consequence of losing compressed air and decide whether redundancy, spare capacity or rental planning is required.
Application data package
Bring the numbers that determine the air station.
The fastest path to the right AIRCENTER SX is a clean demand and site package. Where existing-system behaviour is uncertain, measured demand is more useful than guessing from nameplates.
Air demand
Demand profile
Average, peak and minimum flow; operating hours; shift pattern; major pneumatic users; future expansion.
Pressure
Pressure requirement
Required point-of-use pressure, current compressor pressure, known pressure drops and the most pressure-sensitive equipment.
Quality
Air quality
Required pressure dew point, particle/oil sensitivity, existing filters and any process-specific air-quality standard.
Site
Site utilities
Electrical service, room dimensions, ambient conditions, ventilation, condensate route, piping size and service-access constraints.
