CompAir DH compressors deliver certified 100% oil-free air according to ISO 8573-1 Class 0 (2010) and are completely silicone-free. There is no oil anywhere in the compression process, eliminating contamination risks and ensuring safety for food, pharmaceutical, electronics, and other sensitive industries.
The water-injected screw stage enables very low operating temperatures (below 60 °C) and near-isothermal compression. No internal aftercooler is required, reducing pressure losses and energy consumption while improving overall system efficiency.
The single-stage direct-driven compression element without gearbox, belts, or oil systems significantly reduces the number of moving parts. Fewer components mean lower wear, higher reliability, and reduced maintenance costs over the entire service life.
Regulated-speed (RS) models precisely adapt compressed air production to actual system demand. Without unloaded running cycles, they provide stable pressure and can reduce energy consumption by up to 35% in suitable applications.
Balanced axial and radial forces reduce bearing loads and ensure long compressor element life. There are no oil filters, separators, oil pumps, or complex seals, simplifying maintenance and lowering total cost of ownership.
DH compressors are equipped as standard with the advanced Delcos XL controller and iConn remote monitoring system. The system enables real-time monitoring, data analysis, predictive maintenance, and improved availability and energy efficiency.
CompAir oil-free screw compressors provide 100% clean compressed air according to ISO 8573-1 Class 0, which is essential in food and beverage production. From filling and packaging to conveying and process control – without the risk of product contamination.
Air quality is critical in pharmaceutical production. CompAir oil-free compressors provide stable, clean, and certified compressed air for pharmaceutical manufacturing, packaging, laboratories, and support processes.
Manufacturing electronic components requires extremely clean and stable compressed air. CompAir oil-free compressors prevent contamination of sensitive components and ensure reliable SMT line and production process operation.
In the automotive industry, oil-free compressed air is used for painting, robotic systems, assembly, and production line control. CompAir solutions provide high availability and energy efficiency.
Chemical and process plants require a stable and clean compressed air source for valve control, instrumentation, and manufacturing processes. CompAir oil-free compressors reduce contamination risk and improve process safety.
Reliability is essential in the energy sector. CompAir oil-free screw compressors are used in power plants, energy stations, and auxiliary systems where high availability and clean compressed air are required.
