APS X G3 Series
The APS X G3 screw compressor series from Airpress is a modern range of variable-speed compressors, engineered with high efficiency and low energy consumption in mind. These sophisticated machines are equipped with a European-made screw block, an ultra-premium IE5 motor, a next-generation inverter and an advanced AirVision controller. This combination ensures stable, energy-efficient operation and offers convenient control over the entire compressed air production process. The APS X G3 series is the ideal solution for everyday operation in demanding industrial environments.
These screw compressors are perfect for small and medium-sized industrial plants that require a flexible, efficient compressed air source with variable demand. They excel in applications that need precise energy management and performance monitoring, e. g. in workshops, production lines, and storage systems. The APS X G3 compressors are particularly well-suited for industrial pneumatics, where reliability and energy efficiency are paramount.
Advantages of the APS X G3 screw compressor series:
- Highly efficient, factory-fitted screw module — Designed and manufactured in Europe, the screw system with optimised air and oil circuits ensures high reliability and performance.
- Direct drive 1:1 — The screw module is directly driven (without use of gear transmission), which reduces mechanical losses and extends the unit lifespan.
- IE5 permanent magnet synchronous motor — Together with the advanced screw block, it reduces energy consumption.
- Variable-speed inverter (IVR) technology — The compressor can run within wide operating range, i. e. at lower speeds when compressed air demand is low. This reduces energy consumption and minimises mechanical wear by decreasing the amount of the motor starts. Moreover, the IVR technology ensures smooth start-up, reducing component stress and extending the service life of the compressors.
- Optimised total cost of ownership (TCO) — the factory-fitted European-made screw block and other advanced components lead to reduced downtime, longer service intervals, and stable performance.
- Versatile for applications requiring a pressure range from 7 to 10 bar — At 8 bar, the output increases by almost 20%, providing additional savings.
Energy efficiency comparison for the APS X G3 screw compressor series
Assuming an annual compressed air demand of 100,000 m³ at an operating pressure of 8 bar:
| Model | Motor power (kW) |
FAD @ 8 bar (m³/min) |
FAD @ 8 bar (m³/h) |
Energy consumption (kWh/h) |
Air delivery per kWh (m³) | Energy consumption per 1000 m³ (kWh) | Air delivery for 2000 operating hours (m³) |

Savings vs APS 10 X FS (kWh) |
Savings vs APS 10 X FS (%) |
|---|---|---|---|---|---|---|---|---|---|---|---|
| APS 10 X FS | 7.5 | 0.92 | 55.2 | 7.5 | 7.36 | 135.87 | 110,400 | 1,811.59 | 13,586.96 | 0 | 0 |
| APS 10 IVR X G2 | 7.5 | 1.05 | 63 | 7.5 | 8.40 | 119.05 | 126,000 | 1,587.30 | 11,904.76 | 1,682.19 | 14.13% |
| APS 10 IVR X G3 | 7.5 | 1,277 | 76.62 | 7.5 | 10,216 | 97.89 | 153,240 | 1,305.14 | 9,788.57 | 3,798.39 | 38.80% |
Actual energy savings may be even higher, as the above comparison does not account for additional losses due to frequent start-ups of a fixed-speed compressor and the resulting temporary increase in power drawn from the grid. Due to the variable load profile of the installation (number of starts, load fluctuations, variable compressed air demand), it is not possible to precisely estimate these values, which benefits IVR solutions with speed control.
Configurations of the APS-X G3 series
The APS-X G3 series from Airpress is available in three configurations, so you can easily match the compressor to the existing installation and adapt it to your operation conditions:
- Basic (standalone) version (without an air receiver and dryer) – Ideal where the compressor is supposed to operate within an existing installation having a receiver or a central compressed air treatment station.
- COMBI version (with an integrated 270-litre or 500-litre receiver) – Compact all-in-one solution that saves space in the compressor room and simplifies installation. It is perfect for small and medium-sized plants where a clear, easy-to-service compressed air installation is important.
- COMBI DRY version (with an integrated 270-litre or 500-litre receiver and a built-in refrigerant dryer) – A ready-to-use compressed air station that immediately supplies dry, high-quality air to machines and tools, minimising the risk of corrosion, pneumatic failures and production downtime. This most complete configuration is the ideal choice wherever reliability, air quality and tidy compressor room layout matter.
Airpress warranty and service support
Screw compressors from the APS-X G3 series are covered as standard by a 3-year manufacturer’s warranty, calculated from the installation and commissioning date. For users who prioritise long-term operational security, the warranty can be extended up to 5 years, which significantly reduces the risk of unexpected costs related to downtime and repairs.
In addition, the customer can sign a service agreement with the Authorised Airpress Service. This form of cooperation ensures priority support and comfortable day-to-day compressor use. Under the agreement, the customer receives, among other things:
- service response within 24 hours of reporting a fault.
- free replacement equipment for the duration of repair or overhaul, both during and after the warranty period.
Thanks to this, Airpress APS X G3 screw compressors operate reliably, and any service work does not paralyse production, allowing you to maintain continuity of processes in the plant.
