Compressed air has been reclassified from Class 2 to Class 3.
This paper examines the background and implications of upgrading compressed air cleanliness from Class 2 to Class 3. It provides a detailed comparison of the key differences between the two classes in terms of particulate matter, moisture content,…
What is the normal vacuum pressure in an air compressor oil tank?
This paper examines the normal range of negative pressure in air compressor oil tanks and its impact on equipment operation. For large compressors equipped with independent lubrication systems, the tank’s slight negative pressure is typically maintained between −50…
Air Compressor Room Operating Procedures
The compressed air room is a critical power‑supply area in industrial production, and its proper use and management directly affect equipment life and production safety. This document provides a detailed overview of the daily operating procedures, environmental requirements,…
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…
What is the nitrogen supply pressure in the cleanroom?
The nitrogen supply pressure in a cleanroom is not a fixed, single value; rather, it is determined through a comprehensive assessment of specific process requirements, the specifications of equipment at each point of use, and pipeline‑system pressure losses.…
