Quality Control & Manufacturing
Frequently Asked Questions
For electronics manufacturing, the appropriate compressor depends on the required air quality, pressure, flow and application. For critical processes, oil-free screw compressors or oil-free scroll compressors can provide clean compressed air without oil contamination from the compression process. Variable-speed models are also suitable for applications with changing air demand.
Electronics manufacturing can be sensitive to oil contamination. ISO 8573-1 Class 0 oil-free compressors are designed for applications where compressed air purity is critical, including SMT, PCB manufacturing, semiconductor, cleanroom and precision electronics processes.
ISO 8573-1 Class 0 represents the most stringent oil classification for compressed air. It is used for applications where oil contamination needs to be minimized and the compressed air quality is critical to the production process.
In many electronics applications, an air dryer is required to control moisture and achieve the pressure dew point specified by the production process. Refrigerated or desiccant dryers can be selected according to the required dew point, operating conditions and application.
The required pressure dew point depends on the specific production process and operating environment. Typical applications may require approximately -20°C to -40°C, while more demanding applications can require lower dew points, potentially down to -70°C. The correct specification should be determined according to the equipment and process requirements.
Compressor selection should consider required pressure, air flow, peak demand, operating hours, air quality and future production expansion. Providing your current air consumption and operating pressure allows our engineers to recommend a suitable compressor capacity and system configuration.
