Hydrovane rotary vane compressors are designed for more than 100,000 operating hours. Thanks to only one main moving part and low rotational speeds, mechanical stress is minimized, ensuring highly reliable operation, fewer failures, and long service life even in demanding industrial environments.
HR04–HR07 compressors operate very quietly (from approximately 66 dB(A)), allowing installation directly next to the point of use. This reduces the need for additional compressor rooms, long piping systems, and related installation costs.
Slow vane rotation and low operating temperatures ensure efficient heat dissipation. Combined with an integrated aftercooler, moisture content is reduced, improving air quality and minimizing the risk of equipment damage and process contamination.
Hydrovane compressors are designed for high efficiency even in the standard configuration. The HR07E RS variable speed model further optimizes energy consumption at partial load and can achieve up to 50% energy savings compared to traditional fixed speed solutions.
The simple rotary vane compressor design ensures reliable performance, low maintenance costs, and high adaptability to various industrial applications. HR04–HR07 models are suitable for both constant and variable compressed air demand.
Reliable compressed air supply for continuous production processes, automated lines, and industrial equipment in demanding environments.
Compressed air for assembly, pneumatic tools, painting, and testing processes where stable pressure and uninterrupted operation are essential.
An ideal solution for production, packaging, and transport applications where clean air, reliable operation, and low operating costs are important.
Precise and quiet compressed air supply for laboratory processes, research, analytics, and pharmaceutical manufacturing.
An ideal choice for small production facilities, workshops, and service centers where the compressor is often installed directly at the point of use.
Reliable operation in power facilities, infrastructure systems, and technical rooms with long operating cycles.
