How is oil content in nitrogen controlled according to ISO 8573-1:2010?
ISO 8573‑1:2010 primarily addresses compressed air, but its purity class system for total oil content has been widely adopted for the control of industrial gases such as nitrogen. The standard defines oil as the sum of oil vapor,…
Can a screw air compressor be started frequently?
Frequent starting of screw compressors is not recommended. It can cause motor overheating, shorten equipment life, and increase inrush current on the power grid. This article provides a detailed analysis of the hazards associated with frequent starts, their…
What happens if an air compressor is exposed to the sun for a long time?
Prolonged exposure of an air compressor to direct sunlight can cause excessive operating temperatures, accelerating oil degradation and seal aging, which in turn leads to high‑temperature shutdowns, reduced air output, and component failure. This article provides a detailed…
