Airpol SR scroll compressors are designed as a component of compressed air systems in industrial sectors with higher air quality standards, such as medicine and biotechnology. These compressors provide a source of completely oil-free air, which is ensured by a special scroll stage design.

The oil-free compressed air production technology in Airpol SR means significant reduction of operating costs. There is no need to change compressed air filtration elements (oil filters, separators) or to dispose of the generated condensate.

Airpol scroll compressors ensure high quality compressed air and efficiency tailored to specific requirements and various applications. Their multi-module design with motors ranging from 2.2 kW to 7.5 kW allows you to select the ideal and reliable solution for your compressed air system.

Oil-free compressed air
Airpol scroll compressors provide 100% oil-free compressed air. With the scroll stages used, there is no contact between the metal surfaces of the compression scrolls during the compression process, so there is no need for oil lubrication in the compression chamber. This also translates into easier and cheaper operation of the compressor due to elimination of the need to filter compressed air in the form of installing oil filters, separator, which would require periodic replacement. In scroll compressors, the air obtained is completely oil-free.

Quiet compressor operation
Low sound intensity level of Airpol oil-free scroll compressors results both from low rotational speed of compression scrolls and from the applied sound-proof enclosure. Inside the casing is lined with a sound absorbing material with an estimated sound absorption capacity of 80%. This makes Airpol scroll compressors suitable for installation in virtually any working environment, according to their intended use.

Long service life and reliability
Modern design of the scroll stage means increased service life, lower vibrations of the oil-free scroll compressor and reduced pulsations of compressed air. The scroll compression stage is largely constructed with components that do not move and are completely symmetrical, which has a beneficial effect on balance, low compressor vibration and low noise levels. Compression is continuous, resulting in small pulsations of compressed air. The rotor is mounted on oversized roller bearings to ensure long, reliable operation.

Microprocessor control
The control system based on Siemens microprocessor controller allows for easy and clear monitoring of the compressor status and quick setting of working pressure (within the range of settings permitted by the manufacturer). It ensures a fully safe and automatic operation of the compressor. It protects against, among other things, excessively high temperatures of compressed air, inappropriate parameters of power supply or compressor overload. The controller also enables remote monitoring via a web browser or via a mobile application, which is available for Android and iOS systems. The remote connection gives the possibility to collect some diagnostic information from the controller and allows to view the duplicated operator panel.
