APS 15 IVR Combi Dry X G3, oil-injected variable-speed screw compressor
The APS 15 IVR Combi Dry X G3 with a 500 l tank is a variable-speed screw compressor designed for high output and low energy consumption. It is fitted with a European screw airend, an IE5 motor in the Ultra Premium efficiency class, a new-generation inverter and the AirVision One controller. Together they keep the unit running steadily and economically and let you control the whole compressed air production process with ease. Built for daily work in demanding industrial conditions.
Advantages of the APS X G3 series screw compressors
- The compressor has a high-efficiency new-generation screw module, designed and manufactured in Europe, which delivers higher flow at lower energy consumption
- The screw module is coupled directly to the motor (1:1 direct drive), so no gearbox is needed. This cuts energy losses and raises compressor efficiency considerably.
- The compressor uses the European AirVision One controller, which monitors the unit in real time. It enables predictive diagnostics, minimises the risk of downtime and makes servicing much simpler.
- Pairing the screw airend with the inverter gives a broad variable-speed operating range (IVR): the compressor can run at lower speeds whenever compressed air demand drops. The result is lower energy consumption and less mechanical wear, because the motor starts less often.
- The total cost of ownership (TCO) is optimised and covers the purchase price, energy consumption, consumables and servicing, and the cost of downtime. In practice this means less downtime, longer service intervals and stable output.
- IVR variable-speed technology gives a soft start that reduces stress, extends service life and saves a lot of energy when air demand varies
- Instead of separate 8 bar and 10 bar models, this series is set to 10 bar by default and can be switched to 8 bar directly in the controller. This gives you more flexibility in matching the compressor to your installation and better working efficiency.

Actual energy savings may be even higher, because the comparison above leaves out the additional losses caused by the repeated starting currents of a fixed-speed compressor and the short-term rise in power drawn from the grid that comes with them. Since every installation has its own operating profile (number of starts, load fluctuations, changing compressed air demand), these values cannot be estimated precisely, which works in favour of variable-speed (IVR) solutions.
Additional advantages
- Optimised energy consumption thanks to the inverter, which automatically adjusts motor speed to the current air demand. This allows energy savings of up to 50% and lowers the total life cycle cost of the unit by 30% over 5 years.
- Quiet operation thanks to a radial fan, which keeps the noise level at 63 dB(A), so you can install the compressor close to the point of use.
- Compact design that makes installation easy where space is limited.
What makes this screw compressor so energy efficient?
- Permanent magnet synchronous motor in the Ultra Premium IE5 efficiency class.
- Inverter with enhanced efficiency, allowing energy savings of up to 50% compared with fixed-speed compressors.
- 1:1 direct drive, which eliminates energy losses at the motor.
Recommended use
The APS 15 IVR Combi Dry X G3 compressor with a 500 l tank is a good fit for small and medium-sized industrial plants that need a flexible, efficient source of compressed air with variable demand. It performs well in applications that call for precise management of energy use and output monitoring, such as workshops, production lines and warehouse systems.
Because the compressor is energy efficient, it suits any application where saving energy matters.
